Hello,
I have a main form that contains many form. When i am trying to close the main form by the X control box button, the onformclosing event of the child forms are launched before the main form event (onclosing) are launched.
How can i capte the X button closing in the mainform first?
best regards,
dghdfghdfghdfghdgh

The main form is closing it's children first. This is logical. I am not sure if you can do anything about it.

You can check the FormClosingEventArgs in FormClosing. Allows you to cancel closing the form. I don't really know if the child forms will stay open, but it sounds logical that they will.

You can turn on double buffering,
this.SetStyle(
ControlStyles.AllPaintingInWmPaint |
ControlStyles.UserPaint |
ControlStyles.DoubleBuffer,true);

If you use F2 to rename the file in the solution Explorer, I think it will rename the class for you. Yo ucan also right click on the name and rename it via the refactor menu. Finally, you can just do a global search and replace.

My winform is controled by other software. It use windows api function "sendmessage" send the windows message to my form. The function need 2 parms "form's classname & form's title".
so i must change the classname to specific name like "myForm".

No, you don't need to do that. SendMessage takes a HWND, you can FIND the hwnd based on name or title, using different APIs.

Only works on a "modern" IDE. VS 2003 didn't have the fancy refactoring - this was introduced in 2005.

Which is why I also said 'search and replace' :p

Override CreateParams, and set the class name yourself. Not sure if it will give you an exact name though, but it's worth a try.

Hmm. Doesn't work.

If you want to use SendMessage to send something to a window, do what was mentioned above.
Maybe inherit a NativeWindow, and set the caption to something like "My Special Window". Then you can use FindWindow("My Special Window") to find the handle of the window you want to SendMessage to. All you need to do then is override WndProc in the NativeWindow.
Have a look at FindWindow on pinvoke.net.

3rd party specific questions should be asked on the appropriate site - in this case Infragistics. You are more likely to get help there - provided you have a legitimate version of the controls.

hi
i want to create new Measuring Unit from Main units (like : meter,kilo gram,...) by formula, for example i want to create new unit from this formula :
unit1 = (1.25 * Meter) / 100
or
unit2 = ((1.25 * Meter) / 100) + 91
but i don't know how to do, do i need Regex ? if yes, can u give me a useful articles or sources ?
thanks.

I have no idea where you expect to need regex here, do you want to pull numbers out of a string ? Do you want people to type in the formula ? In both those cases, yes, some form of string mashing is required. Is that what you meant ?
