This is very simple. You shout not Dim a NEW instance of your Form1 because it should already open. Instead call the controls on the already open Form:
Form1.MenuItem1.Enabled = True

Ok, I believe this is called a custom UITypeEditor. What I am trying to do is have a Property that can Expanded and show two Sub-properties for that one. An example of this is the "Size" Type which has an x and y properties.
I want to use this to define a Color gradient.
Example:
BackColor
StartColor
EndColor
ForeColor
StartColor
EndColor
Can anyone point me in the right direction?

I have a vc++6.0 dll(ATL COM), a method in the dll takes a Variant(of type VT_DISPATCH) parameter as input. I am using this dll in vb.Net by imptlb process. The problem is that I am unable to pass the VT_DISPATCH type to my method. I am trying to use DispatchWrapper class as per MSDN but it gives unsupported interface error. Can any one help me out, its a bit urgent. I face the same problem in c# too. A solution in c# or vb.Net will do for me  ).
IDL Method Signature
====================
Compress([in,out] VARIANT* DocumentObject, [out,retval] short* retVal);
DocumentObject is of type VT_DISPATCH.
vb.Net code snippet
====================
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
Dim Comp As New XMLCOMPRESSIONLib.JNIXMLCompressionClass()<br />
Dim XmlDoct As New Xml.XmlDocument()<br />
Dim XYZ As Short<br />
<br />
XmlDoct.Load("C:\DEXML\asdfa.xml")<br />
XYZ = Comp.Compress(DispatchWrapper(XmlDoct)) <br />
MessageBox.Show(XmlDoct.InnerXml)<br />
End Sub
I get error "Interface not supported" when I call compress with dispatch wrapper tyepcast.

Dim i As Integer
For i = 0 To lst.Items.Count - 1

dim a as label
dim a as new label
dim a as new label()
Can I use a.text immediately after one of the 3 dim ways?
Or should I have to add a line "a=new label" before using a.text in the first dim way"dim a as label"?
I hope you know my means.
Thanks.

After the first "dim", a is still nothing so you can't use a.text immediately. You can do so after the other two "dims", however. The recommended way is:
dim a as label = new label()
which is equivalent to the second and the third dim.
|
|
|
|
|
But in fact,I see such dim :
dim form1 as form2(form2 is an user-defined class)
and the app uses "form1.param1"(param1 is also defined in class form2) immediately,not use new pointer first.

Does anyone know how to use the post method to get through two urls to screen scrape information from the second url?
ie - i need to post some values to get to the first url. Then to get to the second url i need to post a second set of values. It's the second url where i need to screen scrape information from. (Note i need to go through the first url in order to get to the second one)
I can get it going in VB6 but not .NET.
Any code, help or suggestions would be truly appreciated.

Here's[^] an MFC article that might point you in the right direction. I've used WebResourceProvider to do exactly what you want to do.

Actually it was the "web scraping" thing that caught my eye at the home page. When I clicked the link I realized I'd enter the black hole.

Are you trying to press enter in the textbox and have your form post-back to the server? I'm sorry, I didn't understand the question.

I was wondering if someone could tell me how to be able to use the default system icons? I set up a Toolbar and an ImageList, and wanted to be able to use the default Windows icons for new file, save, save all, etc. I know the default icons are stored in shell32.dll, but I'm not sure how to proceed. Any help would be appreciated!

I have a program called IconView which can extract icons from shell32.dll . I can't remember where i downloaded it from. If you want it, I can e-mail it to you.

I found the program with a search on Google. Thanks very much for the response.

Hi all
This is my first post in this forum 
Just a small question. Say test = Boolean.
In C# i can do if (test) to do an if.
Can I do If test Then this in VB.NET? Does it have same function? I cant test this as it is part of code generation, but it does compile fine
A simple yes/no appreciated
