I am really sorry for not elaborating the scenario. Below are the details. Steps resulting error 1. I. Open TextPad / MS Word, II. write text III. Copy the content in the clipboard 2. I. Run the C# Application II. Call the method 3.Causes Runtime eroor at Clipboard.SetDataObject(oldData) line ; 4. Error Details : System.Runtime.InteropServices.ExternalException : The requested clipboard operation failed. Code : private void PasteImg(RichTextBox richTextBox1, string imageFileName) { //Copy the previous clipped data IDataObject oldData = Clipboard.GetDataObject(); #region Pasting the image if("" == imageFileName) imageFileName = @"c:\\JayShared\\music.bmp"; Bitmap myBitmap = new Bitmap(imageFileName); // Copy the bitmap to the clipboard. Clipboard.SetDataObject(myBitmap, false); // Get the format for the object type. DataFormats.Format myFormat = DataFormats.GetFormat (DataFormats.Bitmap); // After verifying that the data can be pasted, paste if(richTextBox1.CanPaste(myFormat)) { richTextBox1.Paste(); } #endregion Pasting the image // //paste back the previous clipped data to the clipboard Clipboard.SetDataObject(oldData); //.......... **Error occurs here.........** // }

I posted a link containing all references to articles on codeproject that have to do with XP Visual Styles. I wasn't trying to be a smart ass; I suggest you read some. Any remotely useful information on my blog will be removed immediately. Judah Himango

Unfortunately, no methods exist for what you want to do. I can't really come up with a way to do it either. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

Dear Heath, Thanks for the tips. I will keep in mind for future postings. I tried sending EM_SHOWSCROLLBAR message by P/Invoking SendMessage, But It did not work in my case. However, I could solve the problem by P/Invoking GetSystemMetrics, CreateRectRgn, SetWindowRgn. I am pasting the code for future reference. private const int SM_CXVSCROLL = 2; // [System.Runtime.InteropServices.DllImport("user32")] public static extern int GetSystemMetrics(int nIndex); // [System.Runtime.InteropServices.DllImport("gdi32")] public static extern int CreateRectRgn(int X1, int Y1, int X2, int Y2) ; // [System.Runtime.InteropServices.DllImport("user32")] public static extern int SetWindowRgn(int hwnd, int hRgn, bool bRedraw); public void HideVerticalScrollBar(RichTextBox rtb) { //get scroll bar width int scrollbarWidth = WinApi.GetSystemMetrics(SM_CXVSCROLL); // handle of the region int handleRgn = WinApi.CreateRectRgn(0, 0, rtb.Width , rtb.Height); //change the width of the rtb rtb.Width += scrollbarWidth; //set window region WinApi.SetWindowRgn(rtb.Handle.ToInt32(), handleRgn, true); } Regards, Jay.

Actually, I was referring to how you let the UITypeEditors and what-not "do their job". That was the point I was trying to make. :) Microsoft MVP, Visual C# My Articles

I have done something like this, but I tackled it from the other side. I basically recreated the PropertyGrid's behaviour in my own control, and let the editors/convertors do there work. top secret AdvancedTextBox

Hi Heath, Thanks a lot for sparing your valuable time to solve the problem. Warm Regards, Jay.

Dear Heath Stewart and Gonzalez, thanks a lot for the solution and guidance, it solves the purpose. I am pasting my complete Demo code.This can be helpful to another developers //For running the sample code paste the following in button click event private void button1_Click(object sender, System.EventArgs e) { string strImageToRTF ="";// string to hold rtf code //create the file where rtf code has to be written string strfileName = "ImageInRTFfile.rtf"; FileStream MyStream = new FileStream("c:\\" + strfileName, FileMode.Create); System.IO.StreamWriter MyWriter =new System.IO.StreamWriter(MyStream,System.Text.Encoding.Default); // //Prepare image object from image file Image img = new Bitmap(@"c:\myimage.bmp"); // //get the RTF string from the method ImageToRTF strImageToRTF = this.ImageToRTF(img); // //write the generated RTF string into the file MyWriter.Write(strImageToRTF); // //close Stream Writer and File Stream MyWriter.Close(); MyStream.Close(); // } // // // Method to get the rtf code string from the image object private string ImageToRTF(Image img) { RichTextBox rtf = new RichTextBox(); Clipboard.SetDataObject(img); rtf.Paste(); return rtf.Rtf; } // // Thanks and Regards, Jay.
