I had this one about 2 years ago...
I had put some code inside my "form1" and found that the code ran, but the form seemed to never appear.
If you put a DoEvents after the show, then a Msgbox, you'll see what's happening... Your form is actually loading, but the program is exiting after the form.show method.

If you want to load the form and not exit "Main" until you close the form try using the ShowDialog method of the form instead of the Show method. I think that's what you are looking for.

Re: Display a form in Sub Main()

Thanks Alot!

It finally worked as Benjamin Liedblad said.

I would like to thank all of you who spared your precious time for me.

How to get the command line argument of the other processes in VB using Win32 API?

I've tried ToolHelp functions, Process & Thread functions, WMI, but still can't know how to get the command line argument information of existing processes (not the current process).
It seems that win32_process in WMI could do helps, but the commandline property only works under WinXP/Windows 2003, for Windows 2000, this property does not exists.
Can any one tell me some idea ?
If you could add the example code here, that would be nice !
Thanks.

Do or do not, there is no try.

serialization problem

ok here is the problem I am making a game and the variables work as follows they have a var class which includes the data and a wrapper class which has built in save and load functions which is binary serialization and the var class is accessed through properties now the problem happens when I try to load the var in this case a map it says the object type cannot be converted to the target type
here is some code

I know all the class = new class stuff is wierd but I have to do that if i dont the debug says that the "object reference is not set to an object" when I try to access the variable this I believe is because a class is a reference type not a variable at least until you use new which this maybe the source of my problem but structures cannot have starting values which then will return "object reference is not set to an object" when I try to access the varaibles

Hi there

Being too cheap to go out and buy it before learning VB.NET, I downloaded the 2005 Beta1 of Visual Studio. I wrote some programs, and now I've bought 2003 Standard. I've tried to downgrade the code so much as my GUI (controls, etc.) are all back, my code is (mostly fine) and there's no build errors. However...there's been a few issues that I need some help with.

Private Sub form1_closing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing

It seems that the older framework doesn't support this, but does anybody know of an alternative that will work?

***

Dim connectme As New Net.Sockets.TcpClient()<br />
      Dim server As String = "1.1.1.1"<br />
      If connectme.Connected = True Then //<br />

Property connected as Boolean doesn't exist in this older framework? Anyone else know how to check?

***

For this one, I'm using NotifyIconEX, and with the EXACT same code, the EXACT same controls, references, etc. When I try to set notifyicon1.visible = True, I get "Object Reference not Set to an Instance of an Object".

***

For some reason, whenever I startup this program, Main.vb (the primary form), is ALWAYS blank, even though I have everything set up in the designer. This NEVER happened in VS.NET 2005. I have yet to figure out how to get around this.

***

All of these worked PERFECTLY prior to the code conversion. If anybody could give me ANY advice, it would be GREATLY appreciated.

Hello,

In Visual Basic .Net 2003, you can handle the Closing event with:

Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing

End Sub

I am not sure of the problem here... You should check to see if the startup object is the Main.vb (right click your project inside of the solution explorer, and then select properties. You should see "Startup Object:" with a combobox that has your startup object.). Another thing that could be wrong is that the "Visible" property on each control is set to false.

I hope this helps,

Hi there

Thank you very much for your code sample, I shall try it this evening.

With regards to the second thing, I have tried BOTH of what you said. I don't even get a title for main.vb...just an empty window with an icon...I've narrowed it down to a certain form but it still makes no sense...

Thanks again,

multiple objects in datagrid

VB 6.0

I'm trying to create datagrid type control (5 rows 10 cols) that is connected to an access database table. The data is being pulled from several different tables to feed the main table. A combo box is used to query the data from the different tables.

i.e.
Col 1: plain text, user entry
Col 2: combo box tied to table (user list)
col 3: combo box tied to table (state)
col 4: checkbox weither is active or not
col 5: another combo box from another table
etc.

Data grid may not be the right thing to do. So far I haven't found any reference to this except in vb.net (can't get pass the database connections It's ok if I'm using 1 table with 6 fields). I can creat this form in MS Access but how do I recreat it in VB6.0?

I think you would get a better response in the Visual C++ Forum because it at least allows you to embed assembly code inside functions.

If you're jumping from VB to assembler, I suggest you may well need an intermediate step. You've got my vote for confidence tho.

Microsoft used to publish an excellent book on the subject, I don't know if it's still around, but it's worth having a look on Amazon and also ebay. Sorry, I forget the title, but if you google Microsoft Press assembler, I'm sure you'll find it.

Nope. That's the Intermediate Language that all managed languages compile into.

Assembly Launguage is pretty much a dead art form under Windows. I think Microsoft stopped selling its Macro Assembler about 4 years ago. It's still available as an MSDN Subscriber download though.

What your refering to is actually here[^] on Amazon. There are other titles listed on that page that still cover the topic.

Like I said, in Windows it's a dead art. It's EXTREMELY tedious, but in speed critical code, it can be worth to time to write the machine code by hand for the best possible optimization.

Mind you, the only Visual Studio language that lets you write machine code in-line is C++. None of the managed languages will let you do this.

Dim frmstring As Object = "From2"
Dim frm As Form = frmstring

What do you think those two lines should do? First you assign the string "From2" to the object variable frmstring. Then you want to assign this string into the Form variable frm. This doesnt make sense and is the cause of the error.
