Ok, I'm not a hardcore programmer so I don't do programming very much. I do know how to program I just don't do it much so the problem is I am currently using VB 4.0 I only have this one project to do and so I don't want to spend a bunch of money to buy the latest version so here's my problem:
How do I get the computer to automatically resize pictures in a picturebox using VB 4.0? In VBA the picturebox has a property called "PictureSizeMode". You set that to Resize and the computer will resize the image to the size of the PictureBox at runtime but how do I do it in VB 4.0?

No idea here. You can't even find the docs on VB4 anymore. I started using VB5 back in 1997 and can't find the docs on that either.

I am trying to open a textfile and manipulate it, then display the result in a textbox on Form1. At some point, I want to open Form2 and have the same data from the textbox on form1 displayed automtically in a textbox on form2. I have code written for everything except linking the two textboxes.
How do I do this??

After you've created an instance of Form2 you can manipulate its child objects like you do with any other object. So just set the TextBox's Text property and then call Show(). Assuming that you want to do that somewhere in the Form1 class the simplest example looks like this:
Dim MySecondForm As Form2 = New Form2()
MySecondForm.TextBox1.Text = Me.TextBox1.Text
MySecondForm.Show()

I have a large text file to process in VB6. The file is 11 gig. It is a dump from a mainframe database that I need to clean up (remove trailing spaces from fields etc) before it is loaded into a SQL database. The file has some characters in the data that are interpreted as EOF by VB (these characters will be removed during the clean up) so I can not process the file line by line because the result is incomplete. I can open the file in binary and process it in chunks but LOF is only a long so I run into an overflow error.
I am looking for ideas about how to perform this task.

I thought about how to do it in VB 6 but the only solution I came up with would incorporate Win32 API calls for the file I/O operations. So how about doing it in VB.NET? I mean what you describe does not sound too complicated. You could install the .NET SDK, write the source code with the editor of your choice and finally compile it into a console application. If you want to give it a try feel free to ask if you run into any trouble.
Best regards

Use a splitter program to split the files into small segments, and load them in binary mode. After cleaning, use the splitter program to join the segments. A very good tool that does splitting and merging and more is Total Commander (www.ghisler.com).

Hi,
I am trying to figure out how to set the http proxy server for a webbrowser control. I basically want to have a webbrowser control on a form and let the user specify the URL they want to access (text box), and also select a proxy server from a list of available ones. Any ideas on how to achieve this?
thanks

VB doesn't use the same format for an array that C++ does. VB uses OLE SAFEARRAYs.

The following comes from MSDN Q207931
HOWTO: Pass Arrays Between Visual Basic and C
It is common to call from Microsoft Visual Basic a function in a DLL not specifically intended for Visual Basic, such as Windows API functions. Since the C function expects the address of the first element of the array, you can accomplish this in Visual Basic by passing the first element of the array by reference.
For example, the following is the prototype of a C function that returns the sum of long integers in an array. The first parameter is a pointer to the array and the second provides the number of elements in the array.
long AddLongs_Pointer(long *plArrayOfLongs, long lElements);
The Visual Basic version of the function declaration looks like this:
Declare Function AddLongs_Pointer Lib "MyDll.dll" (FirstElement As Long,
ByVal lElements As Long) As Long
To call the function, use the following code:
Dim MyArrayOfLongs(0 to 10) as Long
Dim lTotal as Long
' Insert code here to initialize the elements of the array
' Calling the function
lTotal = AddLongs_Pointer (MyArrayOfLongs(0), UBound(MyArrayOfLongs) + 1)

Hi,
I need to grab the window title bar from open application windows (any form eg. IE or notepad or any application) and look for a specific word "error".
However, I cannot seem to find any VBscript commands to grab the window title. Can anyone help?
Functions like GetWindowText(), GetWindow(), etc could not be used in my VBscript executable.

In VBScript alone, it can't be done. You'll have to write an external COM component that VBScript can instantiate and use, using WScript.CreateObject, that will do this search for you.

In that case, could you kindly enlighten me further on what is the object to call upon? What is the object which I am supposed to create in order to reference to the get the title bar of all the open windows?
Thank you!

What you call the object is up to you, because you must write the component that will do this search. There is no object that will do it for you.

Hmm actually i mean wat is the component I need to declare like CreateObject("Shell.Application") is the component Shell or others? I had tried Shell but Shell only can get the title bar from IE or folders windows, else it does not read. However, I have to get the title bar from an open application window. Any idea what is the component to use?
Thanx a great deal.

One more time: You have to write the component! There is no component that will do this for you!

Notepad just edits text files. Are you talking about opening and reading the file, or are you trying to the the contents of the Notepad window?
Notepad doesn't put any locks on the files it opens, so use standard file methods to open and read it.
Reading the Notepad window will be much more difficult to do in VB because now your trying to read the memory of another process, something that is "mostly" forbidden in Windows.

Hello !!
I'm very new to VB programming and I would like to call a function I've written inside a dll. The function must receive a pointer to a Byte Array. So I suppose I have to declare something like that in VB:
Public Declare Function MyFunc Lib "MyDll.dll" (ByRef Data As Byte)
Ok, that's work fine but later when I want to call the function and send parameter, this doesn't work:
Dim arrData(0 To 1) As Byte<br />
arrData(0) = SomeData<br />
MyFunc(arrData)<br />
But this doesn't work: comple error ByRef argument type mismatch.
And I tried other things but nothing works... Sometimes the program compile and call the function but if I debug my dll, I can see that the data that is sent is not correct....
Any idea of how I can do that ?
Thanks

hi all,
how to show color palette in vb.net not color dialogbox
Waiting for u r replies.

If you don't want to use the Color Dialog or 3rd party controls, you're going to have to custom draw this, possibly using GDI+. How this is done will depend heavily on how you want it to look. I suggest doing to research on Code Project and/or other sites, searching for "Color Picker".
