Hi Niradhip,
In regards to your query I would suggest you to you set minimized form's WindowState property to Normal or Maximized.
Like:
frm.WindowState = FormWindowState.Minimized
I hope this helps.

I have an MDI app;
This app has 2 forms Form1 and Form2
Form1 has a ComboBox, ComboBox1, which is bound programmatically to a database;
Form2 has a textbox that should display the combobox selection in Form1.
Essentially, what I would like working is:
In the Form1 Button1_Click event,
Dim f2 as New Form2
f2 = new Form2
f2.TextBox1.Text = Me.ComboBox1.SelectedItem.Text
But this does not work.
So I used a Shared variable to retrieve the value of the combobox selection and use that as the value for the textbox in Form2.
Public Class Class2
Private Shared meetName As String
Public Sub New(ByVal mName As String)
meetName = mName
End Sub
'Assign Combobox selection to the variable, used in the constructor
'Provide access to NameOfMeet Property
Public Shared Property NameOfMeet() As String
Get
Return meetName
End Get
Set(ByVal value As String)
meetName = value
End Set
End Property
End Class
In Form1 Button_Click event:
Dim obj As Class2
Try
'Instantiate Form2
Dim f2 As New Form2
f2 = New Form2
obj = New Class2(Me.ComboBox1.SelectedText)
‘While I have instantiated the Class2 (obj), I have not used it anyplace. Is this right?
f2.TextBox1.Text = Class2.NameOfMeet
f2.Show()
Catch ex As Exception
MsgBox("Error: " & ex.Message)
End Try
End Sub
With this code, I get the following display in the Textbox in Form2 (where I would like the ComboBox selection from Form1 to display) ..
“System.Data.DataRowView”.
Your help is appreciated.
Thanks,
Gymnast

It has to do with how you are loading items into your ComboBox control. You must be binding to a DataSource. You may have to set the ComboBox.DisplayMember and ComboBox.ValueMember and then reference the ComboBox.SelectedValue instead of ComboBox.SelectedItem. Perhaps researching these will point you in the right direction.
Hope this helps.

What's the difference between image and picture ? A picturebox will show an image. I'm not really sure what you're asking for, it seems so straightforward. To show something in your app you add it to the form that is shown.

Well thanks for that. I'm obviously far too stupid to click your original bloody link. I really do need you to copy that post down just in case I missed some subtle nuance. I mean, what's the point of clarifying your original post when it's much easier to post the same old crap and hope that the telepathic helpers happen to stumble on your jumbled, inane ramblings. I'm now going to boil my head to remove the despair you've caused.

With the introduction of Vista, my previous VB script code that registers a dll using regsvr32 now fails.
So I've scanned the blogs on the subject and found that calling shellexecuteex will get round the access (elevation) issue.
I found the following code and modified it to call regsvr32
#include <windows.h>
#include <shellapi.h>
int __cdecl main(int argc, char **argv)
{
if (argc == 3) {
SHELLEXECUTEINFO sei = { sizeof(sei) };
sei.fMask = SEE_MASK_FLAG_DDEWAIT;
sei.nShow = SW_SHOWNORMAL; // added 27 Nov
sei.lpVerb = argv[1];
sei.lpFile = argv[2];
ShellExecuteEx(&sei);
}
return 0;
}
so at the Command prompt I type
'executable name' regsvr32 ddlname
and get the following error message (well words to that effect)
"unknown file type. File needs to be associated via Control panel".
If I typed
'executeable name' open filename it works fine and opens the <filename>.
How / what is missing when I run regsvr32 using shellexecuteex?
many thanks,
ian</filename>

I am working in C++/CLI with Windows Forms and I want to have my compiled html help point to a topic specific to where the mouse is pointing (like as a menu item) but I can't seem to determine which control the mouse is hovering over.
private: System::Void FrmMain_HelpRequested(System::Object^ sender, System::Windows::Forms::HelpEventArgs^ hlpevent)
{
Point pt = this->PointToClient(hlpevent->MousePos);
Control^ requestingControl = dynamic_cast(sender);
Control ^ctrl = this->GetChildAtPoint(pt);
Control ^ctrl2 = this->ActiveControl;
if( File::Exists(this->helpProvider->HelpNamespace ) == true)
{
Help::ShowHelp(this, this->helpProvider->HelpNamespace);
}
}
ctrl is the form itself and crtl2 is the last active mdichild in my application.
requestingControl returns the form (same as ctrl)and not the item the mouse is over.
Hope someone can help

I work in vb.net, and each control has it's own Help_Requested event...which fires when you click on the control (the textbox or label or whatever...) while you have the help mode activated. Perhaps it is similar in your language.
Hope this helps.

Got worked out. Here is my final code.
for each ( ToolStripMenuItem ^tmpMS in this->menuMainForm->Items )
{
for each ( ToolStripItem ^tmpCntl in tmpMS->DropDownItems )
{
if (tmpCntl)
{
if ( tmpCntl->Selected )
String ^tmpCntlName = tmpCntl->Name;
OpenHelpForMenuItem(tmpCntlName);
}
}
}

Hi,
I have one remote method (http) which is placed on server (particular machine).
say http://swserver/MMServer
Now I want to check whether that server's method/service is available or not.
Help me out.
Thank you.

There's no other way to do it other than to try and call it. If it errors out, it's down.
You can PING the machine, but that only tells you if the TCP/IP stack is working. It doesn't tell you if the service your method is in is running. There's no way to tell that other than trying to call it.

Did you even open the link? There's an onus on you to actually do some of your own research yourself.

Hi all,
I need a datagridview cell of containing multiple datagridview cell.If it is possible then pls tell the way of code.

If I understand your question correctly, you want what is known as heirarchical data grids.
In maybe version 1.0 this was supported. But in the 2.0 framework on it does not.
The only way to get that working is to either a) write your own heirarchical datagridview or b) buy one.

I'm dynamically populating a tree as the user selects nodes. Prior to clicking on a node, parent nodes actually have no children and after click, they get populated. This results in expandable nodes not having the "plus" sign next to it until after you click on it. Anyone got any ideas on smart ways to make every node have a plus sign, whether it has a child or not?
Thanks,
Jeff

Easy. Give every node a "dummy" child. When a node is expanded, you check the children of the node for the "dummy" child node. If it's there, remove it and populate the children as you see fit.
