The control is dropped on a designer at runtime

Ohh, now I understand.

Youre control is in design mode, or not?
Don't think that the event's are fired in this mode.

Sorry for not realy helping.

Hello,

this.Dispose();

This is not going to work, because you are Disposing the form wich holds the reference to your new form.

Osama123 wrote:
this.Close();

Same here, because the Close method calls the Dispose method.

Osama123 wrote:
frm.Enabled=true;
frm.Visible=true;

This is normaly the default setting, so you shouldn't need it.(But it's not wrong)

Osama123 wrote:
this.Dispose();
this.Close();

You should use this.Hide() instead.

Hope that helps.

All the best,

try this.Hide() instead of close and Dispose.

In the closing event of frmmdi use Application.Exit().

Hope this satisfies ur needs...

You won't get very far making a thumbnail of a wav file because it contains no image elements - it is an audio format.

Generating Text bitmap from Graphics

azusakt6-Dec-06 22:48

Hi, All.

My application have to generate a text bitmap. The text string is inputted by user, and will be drawn on a panel witin a fixed region. so the string is auto wrapped with multi-line.

I would like to save the display text into a bitmap file (same as the preview with auto wrapped). Does anyone know how to do ? Could you please provide me some examples ? Thank you so much !!

Hello,

Do I understand it write, that you have the Text allready in your panel and make a bitmap (like screenshot) from the panel?

Martin

azusakt7-Dec-06 15:08

7-Dec-06 15:08

yes, correct.

I have already used the drawString to draw text on Panel. But don't know how to generate a bitmap.
Here is my example code for drawing the string:

<br />
string txt = "AbcdefgHigklmnopqrstuvWxyz.AbcdefgHigklmnopqrstuvWxyz.***(AbcdefgHigklmnopqrstuvWxyz)@#!!!) (AbcdefgHigklmnopqrstuvWxyZ)ZZZZZZZ";<br />
StringFormat drawFormat = new StringFormat();<br />
<br />
drawFormat.FormatFlags = StringFormatFlags.DisplayFormatControl;<br />
drawFormat.Trimming = StringTrimming.Character;<br />
drawFormat.LineAlignment = StringAlignment.Near;  // start from top line<br />
<br />
g.DrawRectangle(Pens.Red, new Rectangle(100, 100, 200, 500));<br />
g.DrawString(txt, f, Brushes.Black, new RectangleF(100, 100, 200, 500), drawFormat);<br />
<br />

Hello,

You could use the CreateBitmap Method of the panel class.

All the best,

Use the DrawToBitmap method to draw the control on a Bitmap.

You can use the DialogResult object. Any messageBox always returns a DialogResult that contains the name of the button that was pressed (clicked.

<br />
DialogResult result = MessageBox.Show("Write the question u want to ask here", "write the title (caption) of the message box", MessageBoxButtons.YESNO, MessageBoxIcon.Question);<br />
<br />
if(result.toString() == "Yes")<br />
    //Do something cz the user clicked yes<br />

Note: if you are using asp and creating a web application as u stated u can't use the message box directly without referencing to its name space,

you should add the reference: using System.Windows.Forms

hope it helps,

use the add reference and add it
u can use the add reference following these steps:

click on the Project in the main menu,
--> go down to the add reference
--> stay in the .Net tab and scroll down till you find the System.Windows.Forms
--> select it and then click add

now u should be able to use the message box by just writting MessageBox.show(.......)

good luck
