Just for a follow-up. I think it has worked for now. But I won't know until tomorrow. It didn't create an install file, but an application file. Hopefully this will be sufficient.
Thanks again

Great attitude mate, u sound like a complete MVP 
1. The guy has not even completed a single app 1000 comp installation will be a bit less.
2. I think Bill Gates runs to his customers with a floppy disk in his hand (for may be Windows XP).

Hi guys, I need your help in preventing multiple instances of the same window from opening in an MDI parent child window application ? Its urgent ...thanks ...
|
|
|
|
|
What is the question, where are you stuck?
|
|
|
|
|
My question is simple and straight..I want to prevent multiple instances of the same child window from opening i.e. only one instance of a window should open up when i select a certain menu option from the main menu. I hope i made myself clear this time..!!
|
|
|
|
|
One way can be:
use frm.ShowDialog();
This way, unless you have not closed the current child form, you cannot open anyother.
This might be a quick fix for your problem. If you don't want this you might have to google intensly
|
|
|
|
|
yeah..I have tried that approach, but as u say, i was not able to to open up any other window until i closed this one..but tht should not happen in an MDI windows application ..right ?
Can Dispose() method help in this case?

MDI Parent forms contain a collection of it's children (this.MdiChildren). Before you open a new instance of a form you could check this collection if your form exist and simply activate this instance.
|
|
|
|
|
Can you elaborate a bit more...thanks
|

I found the solutions mate:
Form2 frm = new Form2();
if (MdiChildren.Length != 0)
{
for (int i = 0; i < this.MdiChildren.Length; i++)
{
if (this.MdiChildren[i].GetType().Name != "Form2")
{
frm.Show();
frm.MdiParent = this;
}
}
}
else
{
frm.Show();
frm.MdiParent = this;
}
PS: you will have to modify this the above is real quick and dirty.
You will have to check this for each and every form you open.
Cheers.

Can you fire an event inside of an event that is already executing?
|
|
|
|
|
|
Is there anything special you have to do to get this to work because the event inside the executing event is not firing?
|
|
|
|
|
It is possible that you are not firing the event properly, can you pass me the code.
|
|
|
|
|
This is the code:
protected void btnNext_Clicked(object sender, EventArgs e)
{
switch (m_teststage)
{
case "STEP1":
hidMode.Value = "STEP2";
break;
case "STEP2":
hidMode.Value = "STEP3";
break;
}
m_teststage = hidMode.Value;
FormatPageChange();
}
private void FormatPageChange()
{
if (m_teststage == "STEP2") InitialiseDMRGrid();
if (m_teststage == "STEP3") InitialiseTestGrid();
SetPanelVisibility();
SetButtonVisibility();
SetValidatorsEnabled();
}
private void InitialiseDMRGrid()
{
WebGridHelper m_webgridhelperDMR = new WebGridHelper(wgDMR, "", "ID");
wgDMR.PrepareDataBinding += new DataSourceEventHandler(wgDMR_PrepareDataBinding);
wgDMR.InitializeDataSource += new DataSourceEventHandler(wgDMR_InitializeDataSource);
m_webgridhelperDMR.SortColumns += new SortColumnsEventHandler(m_webgridhelperDMR_SortColumns);
wgDMR.InitializePostBack += new PostBackEventHandler(wgDMR_InitializePostBack);
}
If I click the Next button the event fires but when it gets to the InitialiseDMRGrid method it goes in but does not fire the events inside.
|
|

I think the problem is:
You are "adding" the events on button click and not "firing" them. They will fire when they are suppose to fire.
Your code will add the events to, for eg:
wgDMR.InitializeDataSource += new DataSourceEventHandler(wgDMR_InitializeDataSource);
and when the DataSource in initialised then this event will fire. (I guess you have defined the event handlers somewhere else, because I can't see the event handlers for any of the above events.)

I see what I am doing wrong now. Thanks for your help.

This is not good approach by firing an event inside the already firing event.
