Does not matter. The connection type is dictated by what your sending back and forth, not the number of connections...

Nope. It won't be a problem at all.

They both work about the same. Neither one is easier than the other. Like I said, the choice is determined by WHAT your transferring, not how...

None! The .h header files are C++ headers, not Visual Basic.NET. VB doesn't know what to do with C++ syntax. You'll have to rewrite the header files with the stuff you need and convert the code from C++ to Visual Basic, by hand!

Besides, you don't need the header files anyway. All the socket programming API's have been wrapped in the System.Net.Sockets classes in the .NET Framework. The top of the .Sockets classes starts here[^]. You can search CodeProject for articles on 'sockets' as well as searching the rest of the web for examples.

Overflow checking

Is there a way to stop overflow checking at runtime in VB.NET? I have one math calculation that must behave like another system, it could generate a number > 2 billion (<4) which then needs to go into a signed 32 bit integer. I don't want to disable it for the entire program though, just at one spot.

Thanks,
Sean

Can't do that, it's all or nothing.

You can get around this "feature" your describing by doing you calclations in a Long type (64-bit) integer, then shifting the bits to the left by 32 bits then back to the right by 32 bits.

Dim longInt As Long = 3564530340
Dim shortInt As Integer = (longInt << 32) >> 32

Since your trying to simulate the performance of another system, you'll have to be very specific about it's behavior in overflow situations. This is because not all systems store numbers in the same format and not all systems share the same behavior in the same situation. Provide an example of the results to make sure you get the correct behavior in all circumstances.

This may not be the direct application for you to use. But you can give this a try... You can modify the configuration file and install it

Hi,

How to create, Edit and Load help file for each control. Or I would like to know how to write help file for my application for each control.

Any help will be appreciated.

Thanks,

You need not write saperate help files for each control,
what you can do is create 1 help file which has help info
about all controls in your app, and in the control property
provide different help keywords.

I am trying to put a header on each of my columns in my data grid. I have the columns already there, but with a different name from when I made the data relations. For example on column one it has "fldEmployeeId". I just want "Employee ID". I am getting an error while trying to run it. It is telling me that

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dllAdditional information: Index was out of range. Must be non-negative and less than the size of the collection.

The error is on the first line in this part of the code.

What am I doing wrong? I have a total of 6 columns. Any suggestions.

dgPayrollInfo.GridColumnStyles(0).HeaderText = "Employee ID"
        dgPayrollInfo.GridColumnStyles(0).Alignment = HorizontalAlignment.Center        
dgPayrollInfo.GridColumnStyles(1).HeaderText = "Payroll ID" 
       dgPayrollInfo.GridColumnStyles(1).Alignment = HorizontalAlignment.Center        
dgPayrollInfo.GridColumnStyles(2).HeaderText = "Pay Date" 
       dgPayrollInfo.GridColumnStyles(2).Alignment = HorizontalAlignment.Center       
 dgPayrollInfo.GridColumnStyles(3).HeaderText = "Gross Pay"  
      dgPayrollInfo.GridColumnStyles(3).Alignment = HorizontalAlignment.Right        
dgPayrollInfo.GridColumnStyles(4).HeaderText = "Withholding" 
       dgPayrollInfo.GridColumnStyles(4).Alignment = HorizontalAlignment.Right        
dgPayrollInfo.GridColumnStyles(5).HeaderText = "Net Pay" 
       dgPayrollInfo.GridColumnStyles(5).Alignment = HorizontalAlignment.Right

Thank you,

You need to create the GridColumnStyle first, then added it to the GridColumStylesCollection. Just indexing a GridColumnStyleCollection, like your doing, will not create a new column.

    Dim newGridColumnStyle As New GridColumnStyle
    newGridColumnStyle.HeaderText = "Employee ID"
    newGridColumnStyle.Alignment = HorizontalAlignment.Center
 
    dgPayrollInfo.GridColumnStyles.Add( newGridColumStyle )
    .
    .
    .

I am finishing up the deployment package for my first VB.NET application. Is there a way I can add the VB redistributable to my startup project so that it will automatically install before my application, if it isn't already on the target machine?

Thanks!

Dave Kreskowiak6-Apr-04 11:15

6-Apr-04 11:15

No because your VB.NET app won't even launch without the .NET Framework already installed.

You'll have to install the framework during your app's installation. Search CodeProject and www.GotDotNet.com for articles on Bootstrapping Setup.

OK - I downloaded the dotnetfx.exe file and the Bootstrap example. I think I have those correct, but in one of the MSDN article on this, it says that "The following line of code launches a silent install of Dotnetfx.exe:

dotnetfx.exe /q:a /c:"install /l /q"

Nowhere does it say where this code goes, or how it is called. This is my first VB.NET applicationm and things like this are very frustrating. Can anyone tell me how to implement this command? I am trying to put this application on a CD snd set it up so that the install begins automatically when the CD is inserted in the target computer, or the CD is inserted and the user clicks on "Startup" in the "Run" dialog box.

Thanks!

Dave Kreskowiak7-Apr-04 5:55

That command goes inside the Bootstrap sample. i haven't seen the code for it yet, mainly because I've deployed the .NET Framework to all of my client machines so I dont have to worry about this problem...

I'll check into the bootstrap sample and let you know...
