MySQLMove PivotWizard Adds SQL,CSV, MS Access Support and Chart Creation

If you haven’t been following along, MySQLMove is a tool that started out as a way for MySQL developers to do things the free tools to manage MySQL did not manage well. One of these things was the PivotWizard, which originally allowed MySQL developers, who do not have access to a pivot related function, to accomplish so here. As time went on, it became the most popular part of this software. The early versions of the PivotWizard were crude and did just the basics of pivoting data. I first added SQL support. Now I have added Microsoft Access and CSV file support, in addition to MySQL and SQL Server Database support and also have given you the ability to choose from 50+ different chart types to be able to look at your data in different ways. A lot has changed so I am going to go through it again, step by step.

You can download it here. Be sure to remove the old version if you installed it as the default MS install package can be buggy that way about removing it. Below is the directions on how to use the PivotWizard.

When you open MySQLMove you will see the following:

image

Click on the “Pivot Wizard”.

You will then see the screen to allow you to specify your connection type and parameters. If you choose MS Access you can use mdb or accdb file types and can specify if you use a password for it not. If you choose MS Access or CSV, a file dialog box will appear and ask  you to browse to the path your file is located at. If you choose CSV, it MUST be a comma delimited file and you should have a header row to define the columns. (Incidentally I should note that as long as your CSV files are located inside the same directory (folder) you specified in your connection you can join separate files in a query just as if you were joining two SQL tables like so:

SELECT *FROM [Orders.csv] a
INNER JOIN [Employees.csv] b on b.[ID] = a.[Employee ID]

No need for tools like PowerShell, other applications or confusing syntax.)

If you choose MySQL, be sure to precise on your casing of words. For this example, we will check the box for SQL Server and fill in its connection parameters.

I suggest you click on the Test button and verify all is well. I will check it for you before you leave the following screen but may as well get that out of the way now. If you get any of this information incorrect, you can’t proceed until it is fixed.

Once this is done, click the “Next” button.

image

You will then be asked to type or copy and paste a query based on this connection into the textbox. If you chose CSV format in the earlier screen this information will be filled in for you. After  you enter the query, you must click the “Parse” button. This will verify your connection is correct and your statement compiles. If it does, you will be told via message box how many columns you have to work with and then you will click “Next” to proceed. If it does not compile correctly, you will be informed and you will have to fix the statement to be able to proceed. (Please don’t email me about those kinds of issues. I really don’t have time for that.). You might also see a prompt letting you know it compiled with errors. As long as the issues aren’t fatal, you will be allowed to proceed and a report will be given to you letting you know what the problems were. Below the query box, you are asked to identify what you want Excel to call your report. Since this is the raw data, I called it “Raw Data”. This field is not mandatory. You might also notice the “?” mark icon. On the previous version, I attempted to have you directed to links to the MySQL Facebook group to answer common questions. That was a miserable failure. Instead in this edition, I have placed a tooltip that when you hover over the icon, it gives an explanation of what is going on.

Once this step is completed click the “Next” button.

image

Here you will pick what columns you will want to appear as the rows in your pivot report. You can select multiple columns as rows, just be sure they are related somehow. Once selected you are allowed to choose a name for the field. Excel will use that name instead of the field name in your report. Click the “Next” button to continue.

image

You will then be asked to choose “data” for your report. In this case I have chosen to see how many Order_IDs exist for each salesman (see the last screen). Use the arrows to choose your fields (you can have more then one, and you can reuse the same field if need be.) and select a grouping to be applied. Click the “Next” button to continue.

image

You will then be asked to choose the columns you want to represent in your pivot report and how you want the data grouped. If  you notice we choose to see Order_Date twice in our columns because we want it grouped by Quarter and inside that quarter, by Day of Week. I add a column to your original query with the same name and data with a “_1” after it. So now we have asked to see how many orders our salesman did, divided into quarter and inside that quarter by Day of Week. Play with it, you will get the hang of it. Click “Next” to continue.

image

Here you choose the type of chart to represent the data you have requested and in Chart Title have given Excel the information it needs to call your sheet and chart name what you want. Hopefully the images of the charts you see will assist you in making the choice of charts that you want. Click the “Next” button to continue.

image

Finally, at the end. Now you can give your pivot report a name for Excel to use for your pivoted data (or not if you don’t care) and then click the “Finish” button. Be patient, it takes a few second for Excel to show you your work. Just as a word of caution, I tried to anticipate anything you could do wrong in naming your charts and reports. If something you should happen, you will get a notice of what the problem is but it will allow you to still see what you have produced. It just will not give the worksheet name you tried to give it.

You can see the sample we produced here.

The next version of this software will allow you to save templates of different reports and allow you to create more then just one query. The next version will allow you to store multiple connections, multiple querys and pivot reports and charts specific to each query, each produced into the same Excel Workbook. Keep an eye on here and on the MySQLMove Facebook page for updates.Again you can download the install package for MySQLMove here.

Well that about covers it. Well not quite. I have been asked if I would be willing to do a custom version of this for a specific person or company. The answer is of course, yes. Also if you have bugs you have seen please let me know. Just email me at kellyjmartens@hotmail.com and I would be happy to help.

Save Control Settings with vb.net

What’s this you say? A new blog entry? If you haven’t completely deserted me …. well I don’t know what’s wrong with you! Smile jk. But anyway here is the latest. I am working for a national hotel chain in Memphis, TN. I got married, moved to New Jersey and am we are now separated. Yes it is a long story and no I am not going to bore you with the details!

Before I go any further, I actually write very little in vb.net anymore. The language is awesome. It’s just that very few people want that skill set now and if you want to be employed you need to write in C#. It’s just the way it is. However in this particular task, I found vb.net to be the tool of choice here. The reason is there is no C# equivalent to VB’s implicit ‘once only’ variable initialization within loops. I am not sure why that is but that is the case here. This code snippet is ideal when you want to allow the end user to dictate how a given control is to look or operate. Yes in my example I am using an Infragistic control so if you copy and paste this do NOT email me complaining about broken references please! I hope you find the code useful and thank you for showing up! Smile

Show All Forms In A Project with C#

This will list all forms or other types you specify that are in your particular Visual Studio project. It is a continuation of redoing code I have previously done in vb.net for C#. It can come in handy when documenting your code during your project. If it’s a form, do a certain set of actions, a class then do another set of actions and so on.

You can find the vb.net version here. There were some changes made from that version.

Have a great day!

static void GETALLFORMSINPROJECT()
       {
           System.Reflection.Assembly myAssembly = System.Reflection.Assembly.GetEntryAssembly();
           Type[] Types = myAssembly.GetTypes();
           foreach (Type myType in Types)
              
          {
               if (myType.BaseType == null) continue;

               if (myType.BaseType.FullName == “System.Windows.Forms.Form”) MessageBox.Show(myType.Name);

               //else { MessageBox.Show(myType.Name); }      
               
           }              
        }

Check if SQL Database Exists with C#

Good Morning! I wanted to give a shout out to another blogger who linked to us yesterday here. It was so nice of him you know? Just amazing, the generosity of some folks out there!

Today’s code was a rewrite of the vb.net code here but using C#. One thing of note is that the Using keyword has a completely different meaning in C# so thus has been removed. It wasn’t really needed anyway.

Anyway, so make it a great day!

public Boolean testDatabaseExists(string server, string database)
        {
            String connString = (“Data Source=” + (server + “;Initial Catalog=master;Integrated Security=True;”));
            String cmdText = (“select * from master.dbo.sysdatabases where name=\'” + (database + “\'”));
            Boolean bRet;

            System.Data.SqlClient.SqlConnection sqlConnection = new System.Data.SqlClient.SqlConnection(connString);
            System.Data.SqlClient.SqlCommand sqlCmd = new System.Data.SqlClient.SqlCommand(cmdText, sqlConnection);
           
            try
            {
            sqlConnection.Open();
            System.Data.SqlClient.SqlDataReader reader = sqlCmd.ExecuteReader();
            bRet = reader.HasRows;
            sqlConnection.Close();
            }
            catch (Exception e)
            {
            bRet = false;
            sqlConnection.Close();
            MessageBox.Show(e.Message);
            return false;
            } //End Try Catch Block
                      
           
            if (bRet == true)
            {
                MessageBox.Show(“DATABASE EXISTS”);
                return true;
            }
            else
            {
                MessageBox.Show(“DATABASE DOES NOT EXIST”);
                return false;
            } //END OF IF

           
        } //END FUNCTION

Write DataTable to an MS Word Table Efficiently with C# using a Dynamic Type

This is a C# adaptation of the code I wrote to write a datatable to a Microsoft Word document table for vb.net . But that doesn’t really begin to tell the story here. In vb.net we have been accustomed to being allowed to leave parameters empty when automating the creation of a table in Microsoft Word. C# has not permitted me that luxury which to be honest is probably a better code practice. So prepare to meet the Type.Missing object! In addition the default item that we learned to love/hate in Visual Basic for Applications (VBA) code years ago also is not used in C#. Finally in declaring the range object for the table it became an opportunity to use the new dynamic reference type keyword, which was designed for such situations. Check out this video on the subject which is quite excellent.

http://channel9.msdn.com/Shows/Going+Deep/Inside-C-40-dynamic-type-optional-parameters-more-COM-friendly/player?w=512&h=288

For these reasons you will see key differences between the two sets of code. Don’t forget to import Microsoft Word as a COM reference and do your import statements. As always feel free to comment or email. Have a great day!

using Office = Microsoft.Office.Core;
using Word = Microsoft.Office.Interop.Word;

public void CreateWordTableWithDataTable(DataTable dt)
        {
            int RowCount = dt.Rows.Count; int ColumnCount = dt.Columns.Count;
            Object[,] DataArray = new object[RowCount + 1, ColumnCount + 1];
            //int RowCount = 0; int ColumnCount = 0;
            int r = 0;
            for (int c = 0; c <= ColumnCount – 1; c++)
            {
                DataArray[r, c] = dt.Columns[c].ColumnName;
                for (r = 0; r <= RowCount – 1; r++)
                {
                    DataArray[r, c] = dt.Rows[r][c];
                } //end row loop
            } //end column loop

            Word.Document oDoc = new Word.Document();
            oDoc.Application.Visible = true;
            oDoc.PageSetup.Orientation = Word.WdOrientation.wdOrientLandscape;
           
            dynamic oRange = oDoc.Content.Application.Selection.Range;
            String oTemp = “”;
            for (r = 0; r <= RowCount – 1; r++)
            {
                for (int c = 0; c <= ColumnCount – 1; c++)
                {
                    oTemp = oTemp + DataArray[r, c] + “\t”;
                  
                }
            }

            oDoc.Application.Selection.Tables[1].Rows[1].Select();

            //gotta do the header row manually
            for (int c = 0; c <= ColumnCount – 1; c++)
            {
               oDoc.Application.Selection.Tables[1].Cell(1, c + 1).Range.Text = dt.Columns[c].ColumnName;
            }

            oDoc.Application.Selection.Tables[1].Rows[1].Select();
