• Visual Basic Where to look to find the list of all Visual Basic events...

  I have a looked in books as well as on-line and I can't find a list of all the possible events for Visual Basic and Windows Forms. Thanks, Claude.

• Windows Forms Importing text files

  Greets all, I have several comma-delimited files that we buy from a supplier that need to get into our database. Since we have to do some formatting to the data we already have an app that does this however it takes a VERY long time to do this.   So far the problem seems to stem from avoiding duplicates. Ex. If I get a list of  ...Show All

• Visual Studio How-to: create a custom tool that runs directly against a model file

  The T4 engine that ships with the DSL tools gives you a flexible way to generate text output based on the contents of a model by running a custom tool against a template.   However, in a production environment, you may not want a user of your designer to have access to the template. You might prefer the user experience to be more like that provided by the Microsoft dataset generator, where the custom tool runs directly against the model file, rather than against a template.   This is very easy to do using the May release of the DSL tools.   1) Create and test your template as normal, but then put in a placeholder ...Show All

• Visual C# What determines DateTime.Today.ToString() output?

  I have the situation where in a simple console application, DateTime.Today.ToString() returns .. "2/9/2005" on one machine and ... "2.9.2005" on another. (the date separator is changed). It's important that I get the date in the first format (slashed), and change my code everywhere is a challenging task. I'm looking for a configuration solution to this problem, not a code solution. Does anyone know what determines the format of the ToString function Regional settings don't seem to make an impact, even after a restart. Both machines are running W2k SP4  and  .NET 1.1.4322 Many thanks, Mike Zemek ...Show All

• .NET Development Exception: DataTable internal index is corrupted: '5'. on ...

  Hi, I have a problem with bindingsource component in framework 2.0. I have a combobox bound to a bindingsource which is also bound to a dataset with 2 related tables and a datagridview bound to the same bindingsource. What I want to do is : When the selectedindex property of my combobox changes, the corresponding cell value must be changed in the datagridview. But although the value in bindingsource changes, datagridview does not display the new value. That value is displayed after I move the mouse over that cell and make it invalidate its region manually. Another error I caught is the one that you can see as the subject of my po ...Show All

• .NET Development DataAdapter.Fill() is necessary?

  Hi all, In ADO.NET 2.0, there's a new method called DataTable.Load (DataReader) method, so is it necessary to use DataAdapater.Fill(DataSet) anymore I think all developers don't mind to write a few more line to change .Fill() to .Load() if the performance can be improved greatly after moving from DataAdapter to DataReader (as DataReader is native and fastest approach in retrieving record). Thanks, In MSDN doc, it says: The Fill method retrieves rows from the data source using the SELECT statement specified by an associated SelectCommand property. Also SqlCommand calls ExecuteReader() to retu ...Show All

• Windows Forms Control.Enabled=False - becomes ugly. Why?

  And it is incredibly difficult to do something about it. Eg. combobox don't respond correct on Paint and BackgroundPaint event. I like the old VB60 look - it is much better then today’s solution. I have found out that deep into the control class is the gray value stored and set. Why not let us (developer) control what colour to use when enabled is false I have seen some nonsense explanation why the solution is selected. One was that Microsoft was not willing to spend the money needed to fix it. Another one was that this was a good solution! Microsoft – are you going to fix this problem When will we receive the fix ...Show All
