create a backgroundworker for saving the data.
Before calling the RunWorkerAsync() method show your image.
In the BackGroundWorker_RunWorkerCompleted Method you can hide the image again.
You use the BGW (backGroundWorker) to prevent a freeze of the form
If you use a _RunWorkerCompleted-method (reporting the progress) you can even change the image into another image!

Hi,
Using SourceGrid, unable to use "CopyPasteSelection" from ContextMenuStyle enum....
I am using SourceGrid to display my records, with editable cell. I have a requirement to copy/paste existing row in new row. But here this grid has been little bit customized for some purpose. We are using another class file to doing this, and this class generates the object of Grid. Now this is the problem here, I am not getting the enum item to set the "ContextMenuStyle".
I can set SelectionMode like this :
this.Selection.SelectionMode = GridSelectionMode.Row;
but unable to set ContextMenuStyle :
this."ContextMenuStyle:NOT ABLE TO FIND THE ENUM IN THE LIST TO SET" = ????
Please someone help, or give some idea to resolve this Issues. I am not sure that this been affected by customization.
Thanks in advance.
Kind Regards: Madhusudan

i have a splitcontainer on my mdi-parent form,
i want to use the right panel (panel2) as the mdi client area
i tried the following code:
childform.MdiParent = this;
childform.Parent = this.splitContainer1.Panel2;
childform.Show();
I can now select the client window inside the panel and drag it.
but the border of the client window still appears like it is not active. 
what am i doing wrong?

Apparently, the MdiClient control (which contains MDI children) is docked to fill the parent window. What I have done in the past is create a regular Splitter[^] (not a SplitContainer) and dock it to one side of the main form (left in your case), next to the panel you want to resize. That way you get a resizable panel docked to the side, with the MdiClient control covering the rest of your window.
I hope this helps!

 thanks, but i think you missunderstood my problem, there is no problem with the docking and i can select the child window, drag it it all works.
only the active mdi child window doesnt look like it is active:
this is what i mean with a window being active or not active:

just something with the appearance...
i can't show you a screenshot at the moment (working on a different computer now)
but thanks anyway.

I think your problem lies in setting the Parent property to be different than MdiParent. I have never verified it, but I assume that when you set the MdiParent property of a form, if that parent is an MDI container, the actual parent of the MDI child is the MdiClient window (see this article[^]) in the parent's client area.
When you change the parent of the MDI child, something probably is not right.
Anyway, if you could show us a screenshot, we could get a better idea of what you want to achieve.

 i am very sorry but i was the one who didn't understand...
i tried your first response
and it works now (and it's a simple solution  )
the double buffer in the example program (article) is slowing things down on my pc,
so i didnt use that one (especially when the application is maximised)
thanx
|
|
|
|
|
I am glad I could be of help
The article link was mainly to give you some information on the MdiClient control. The double buffering is not required
Have a nice day!

It doesnt have a "Font" property, so AFAIK, the Style can't be changed..
You CAN do the following though...
private void button1_Click(object sender, EventArgs e)<br />
{<br />
toolTip1.BackColor = Color.Black;<br />
toolTip1.ForeColor = Color.Yellow;<br />
toolTip1.SetToolTip(this, "Booya!");<br />
}
|
|
|
|
|
But the tooltip cannot been found in ToolStripItem.
Maybe I can get it by reflection,my purpose is to change the fontsize. how to do it ?
thank u!
|
|

Don't think you can do font size :/
I was doing tool-tips for an inventory in a game I was making, and the best I could do was making a semi-transparent form that appears relative to the mouse X/Y co-ords on Mouse_Over :/
Soz :/

Hi friends,

Hi Vijay,
Please know that the detault checkBoxes in DataGridView does not have any property to check whether the checkbox is in Checked/Unchecked state. However, on the basis Value property we can check the state in the following manner:
BEGIN CODE
Dim flag As Boolean = False
flag = Me.DataGridView1.Rows(3).Cells(9).Value
If flag = True Then
MsgBox("State is Checked")
Else
MsgBox("State is UnChecked")
End If
END CODE
Hope this helps .

I am trying to use .NET delegate to make the form responsive while doing data retrieval.
The form contains lots of controls including a tabcontrol with tabpages.
When i Click the Search Button to retrieve the data, i invoke the LoadRecord Delegate and the RetrieveRecord Method was called, but when i click the next Tab Page the form hangs. Can anyone help me with this?
Heres the codes..
frmBase
Code Snippet
Private Delegate Sub LoadRecordDelegate()
Private LoadRecord As LoadRecordDelegate
Protected Sub ExecuteRetrieveRecord()
LoadRecord = New LoadRecordDelegate(AddressOf RetrieveRecord)
LoadRecord.BeginInvoke(LoadCallBack, LoadRecord)
'Retrieving
End Sub
Protected Overridable Sub RetrieveRecord()
'Override this
End Sub
Private Sub LoadCallBack(ByVal result As IAsyncResult)
LoadRecord.EndInvoke(result)
'Done Retrieving
End Sub
frmMyForm
Code Snippet
class frmMyForm
Inherits frmBase
Protected Overrides Sub RetrieveRecord()
Me.SearchRecord(ReferenceNumber)
End Sub
Private Sub SearchRecord(RefNum as String)
'Some Codes to retrieve information based on the RefNum
'Populate the controls(textboxes,comboboxes,etc.)
End Sub
private sub BtnSearch_CLick
mybase.ExecuteRetrieveRecord
end sub
End Class

Hi,
seems to me you are making illegal cross-thread calls, i.e. accessing Controls by a
thread other than the one that created the Controls.
You can try this in .NET 1.x, or in later .NET versions provided you disable the
cross-thread checkking. Anyway it is the wrong way of doing things, it normally results
in a non-responsive or hanging GUI.
The right way to access Controls from an arbitrary thread is by using Control.InvokeRequired
and Control.Invoke; there is documentation and lots of examples everywhere.

first: all questions on the forum are urgent.

You start to print, request data and than print the data?
Is that your problem?
