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.

Thanks Christian,
I would also like some more help from u.
can i paste any object on the Richtextbox i.e. if i paste a form or a panel on a richtextbox and enter text on the Richtextbox the text should not go behind that panel / form. Is that possible .
OR is there any way to insert a table on the RichTextBox as we insert the table in MS-WORD.
Waiting for Reply.....
Regards,
Pramod.

No, in every case, you're talking about a control you will need to create yourself.

Now i have a Main richtextbox placed on a form and i try to create a table using forms and placing Richtextbox on the Forms. Each form looks like the cell of the table,
Now the problem is that i have to print the contents of the Richtext in each forms in the tabular form

you can insert table in the same way i told you in draw rectangle or if you want more elegant way you must deal with RTF syntax and i think this way Ms word work -Not sure- RichTextBox have Rtf Property which you can set to rtf for example the following code will draw table with one row and three cells
{\rtf1\fbidis\ansi\ansicpg1252\deff0{\fonttbl{\f0\fnil\fcharset0 Times New Roman;}}
\viewkind4\uc1\trowd\trgaph108\trleft-108\trbrdrt\brdrs\brdrw10 \trbrdrl\brdrs\brdrw10 \trbrdrb\brdrs\brdrw10 \trbrdrr\brdrs\brdrw10 \clbrdrt\brdrw15\brdrs\clbrdrl\brdrw15\brdrs\clbrdrb\brdrw15\brdrs\clbrdrr\brdrw15\brdrs \cellx2952\clbrdrt\brdrw15\brdrs\clbrdrl\brdrw15\brdrs\clbrdrb\brdrw15\brdrs\clbrdrr\brdrw15\brdrs \cellx5904\clbrdrt\brdrw15\brdrs\clbrdrl\brdrw15\brdrs\clbrdrb\brdrw15\brdrs\clbrdrr\brdrw15\brdrs \cellx8856\pard\intbl\ltrpar\lang3073\f0\fs24 Cell 1\cell Cell 2\cell Cell 3\cell\row
\pard\ltrpar\fi-108
\par }
this things you see are rtf syntax of the table
for its Specificationlook at Rich Text Format (RTF) Specification, version 1.6[^]
to see this things in action create new appliction put rRichTextBox and textbox or hardcoded this syntax in string variable in somewher in your application write
<br />
richTextBox1.Rtf=textBox1.Text;<br />
or richTextBox1.Rtf=yourStringVariable;
this will draw the table
i hope this help you but i think that if you make your application automate MS-Word may it will be easier
NOTE SORRY FOR THE WIDTH OF TEXT BUT I DIDN"T NOW HOW TO CONFIGURE IT

You can work around this by draw rectangle in Bitmap and then copy it into clipboar and paste it in Richtext box
some thing like the following code
Bitmap bm=new Bitmap(26,14);
Graphics g= Graphics.FromImage(bm);
g.DrawRectangle(Pens.Red,0,0,25,13);
g.FillRectangle(new SolidBrush(Color.Yellow),1,1,24,12);
Clipboard.SetDataObject(bm,false);
IDataObject rect=Clipboard.GetDataObject();
if(rect.GetDataPresent(DataFormats.Bitmap))
{
richTextBox1.Paste();
}
bm.Dispose();
g.Dispose();
you have to handle mouse events of richtextbox to create the bitmap and copy and paste it

I'm pretty sure you cannot do that in C#. You should search a Win32 DLL and use it with PInvoke or DllImport.
try here www.pinvoke.net

hi all,
How am I open Excel File page on windows Form?.Is there a library to Load Excel file and read it using C#?
thanks in advance.

Why dont you at least try to use the search[^] function?
You'll find plenty of hits which basically seperate into those who use automation and others that use Ado.Net. Which one is better depends on your requirements.

Hi :
How can I darg-drop item to a WebBrowser control ?
I created an application written by C#,it includes two forms , one form
includes a TreeView control , the other includes a WebBrower control and a
TextBox control, now we call them as Form1 and Form2.
First , I try drag a item to the TextBox control,(I have set TreeView for
drag well ) I set
"this.textBox1.AllowDrop = true;" then add Events and write these methods:
this.textBox1.DragOver += new System.Windows.Forms.DragEventHandler
(this.textBox1_DragOver);
this.textBox1.DragDrop += new System.Windows.Forms.DragEventHandler
(this.textBox1_DragDrop);
this.textBox1.DragEnter += new System.Windows.Forms.DragEventHandler
(this.textBox1_DragEnter);
Run this application,and drag item from TreeView which in Form1 to TextBox
which in Form2,the TextBox 3 Events (DragOver,DragDrop,DragEnter) is done
well.
But when I want drag item to the WebBrower,I can not find DragEnter Event and
others Events related to "Drag-Drop",so I can not drop Item to WebBrowser.
Also I have tryed set WebBrowser's Document.DesignMode="On",but can not drop
too.
Then I Write a HTMLBody's ondragenter Event ,but this ondragenter() can not
trigger.
So I think it must be solved by COM knowledge.
Can any one give my some suggestion,
because my COM knowledge is poor, if anyone give me an all solved code ,I
will be very appreciated.Thanks very

I'm looking for feedback if the following makes sense:
- I declared an Interface IDocument:
public interface IDocument
{
bool IsDirty { get; }
void Save(System.IO.Stream stream, bool resetDirty);
void Load(System.IO.Stream stream);
}
A Helper class implementing the Open/Close/Save/SaveAs/AskForFilename UI should work wiht the document(s) through this interface.
I'm a bit uneasy with the Load/Deserialize design: DeSerialize returns an objec. This makes sense but:
- I can't have a static Load method in the interface
- doesn't allow to implement "Revert"
So I did implement Load the following way:
public void Load(System.IO.Stream stream)
{
System.Xml.Serialization.XmlSerializer ser =
new System.Xml.Serialization.XmlSerializer(typeof(RTDocument));
RTDocument loaded = ser.Deserialize(stream) as RTDocument;
Root = loaded.Root;
}
Is this exceptionally stupid? Some better way?

Yeah, I arrived at that point, too.
I *think* it can be does by constructing a generic Document Manager just using the typeof(document).
Q: is it possible to override the default "[Serialize]" imlementatìon?

Sure - inherit from ISerializable and then override the GetObjectData(SerializationInfo info, StreamingContext context) method. You may also need to supply a special constructor for your class (protected MyClass(SerializationInfo si, StreamingContext context)) - MSDN has conflicting info on this (see ISerializable[^] and Custom Serialization[^])
