All controls in c# inherit System.Windows.Forms.Control.
You can create such a control that draws a specific thing when you call the procedures you add to it. The question is how to draw onto the control? The answer is the System.Drawing.Graphics Class. Get the associated Graphics to you control with CreateGraphics and do your drawing, the control changes it's (visual) contnents afther a refresh.
I hope you understand...because is a rough world out there...

i have downloaded new Message from outlook into my local folder i have problem in displaying it in winforms(C#)
|
|
|
|
|
There is string in the statement.
For example, SQL statement in C#.
strSQL="Select * "
" from TB1";
|
|
|
|
|
strSQL="Select * " +
" from TB1";
|
|
|
|
|
Another way is
strSQL="Select * ";
strSQL+=" from TB1";
|
|
|
|
|
strSQL = @"Select *
from TB1";
works as well. It's useful for putting long formatted strings in code.

You can specify the version of the runtime required by your application in configration file in requiredRuntime element you can specify which versions of the common language runtime that your application supports in supportedRuntime
elment look at startup Element[^]
requiredRuntime Element[^]
supportedRuntime Elemnent[^]

I'm importing a COM interface definition into C#, and I came across a method that has a parameter:
[out, iid_is(riid)] void **ppvInterface
This parameter is used to pass a COM interface reference out to the caller, which in this case will be managed code. The use of void**, is, I believe, due to the fact that the interface reference passed to the caller may be either IDispatch or IUnknown.
I know how to deal with cases where the base interface (between the two) that the interface is derived from is known - make the argument be of type object, and then add a MarshalAs attribute, specifying either UnmanagedType.IUnknown or UnmanagedType.IDispatch. But what should be done when the interface could be derived from either one?
TIA!

Recently I design a custom comboBox control,this control includes two forms.The one of the forms is inherit from the namespace that System.Windows.Forms.ComboBox,When active DropDownEvent,The second form will be shown.But the focus is moved on the new form.
However,I want keep the focus still on the main form.
Will you help me,please? Thanks.
MSN:tomatoboy78@hotmail.com ，you can email to me.;)

From what I understand you have two forms : a mainForm, and a "dropDownForm". When you press the drop down button you wish to show the dropDownForm but keep focus on the mainForm. If you do that the dropDownForm will not be visible (only if you make it allways on top, whitch is not a good thing, let's say you switch to an other aplication...in this case you will see the dropDownForm). I recommend you to forward all the focus actions you wish to keep onto the mainForm from the dropDownForm.
I hope you understand...because is a rough world out there...

Is there anyone can help???
I am trying to get and set the content of some page items those have
a particular associated xml element. And this is what I tried:
InDesign.Application indesign;
Type t = Type.GetTypeFromProgID("InDesign.Application", true);
indesign = (InDesign.Application)Activator.CreateInstance(t);
InDesign.Document doc = indesign.ActiveDocument;
InDesign.PageItems items = doc.PageItems;
System.Collections.IEnumerator enu = items.GetEnumerator();
while (enu.MoveNext())
{
// this is ok, giving System.__ComObject
// which is useless information
MessageBox.Show(enu.Current.ToString());
// but this is not, giving InvalidCastException
// What object type is it meant to be ????
PageItem i = (PageItem)enu.Current;
MessageBox.Show(i.Id.ToString());
}
I also tried doc.AllPageItems, but it gave me the same exception.
Thank you for any help.

I have Visual C++ lib file, but I also want to use C# to write my program. How can i do? Can I use Visual C++ *.lib into C#?
Second problem:
Is it same the writen methods with Visual C++.NET & Visual C++?
|
|
|
|

Nop, you can't use .lib on c#, but, you can use Interop and call functions in a DLL.
Second, Visual C++.Net can compile projects made with Visual C++, but Visual C++.Net can compile managed C++ programs also.

The best you can do is to write a mixed-mode wrapper around the classes in the library and then use that wrapper from C#.

No, VC++ .NET generates IL, VC++ code is compiled to machine code.

Hi All,
I Have two RichTexBoxes on a form vertically one above the other.
Now i want to draw a rectangle on the Richtextbox like we draw in MS-WORD.
This rectangle should allow the user to enter text within it.
and if the rectangle is dragged by holding one of it's end the size of the rectangle should increase. if the size of the rectangle increases more than the Richtextbox's size the rectangle should be continued on the next Richtextbox.
What i want to achieve is the same that we do in MS-WORD.
I dont know whether it is possible or not.
Please help me out,
Waiting for reply
Rgards,
Pramod

Nope, you can't do it. A richtextbox is a box for text only. You'll need to create your own control to draw text and graphics, and to control the input area like this.

OR is there any way to insert a table on the RichTextBox as we insert the table in MS-WORD.
Waiting for Reply.....
