I have a windows form with several richtextboxes. I have created a button which fires the fontDialogue to change the style of the selected font.
When I select the text to be changed and then click the button to change the font style the richtextbox control loses focus. However the style still gets applied to the tex that was selected.
The problem I have is when changing the font style of text within another richtextbox the previously selected text from the first richtextbox changes also.
How can test to see which control has text selected?
Here is the button event trigger:
private void btnFontStyle_Click(object sender, System.EventArgs e)
{
if(this.fontDialog1.ShowDialog() == DialogResult.OK)
{
foreach(Control ctrl in this.pnlMain.Controls)
{
if(ctrl.GetType() == typeof(System.Windows.Forms.RichTextBox))
{
if (((System.Windows.Forms.RichTextBox)ctrl).Modified)
((System.Windows.Forms.RichTextBox)ctrl).SelectionFont = this.fontDialog1.Font;
}
}
}
}

It would appear that you have a design flaw in your application. Both RichTextBox's will maintain their own Selection's whether they have the focus or not. Since your code is interating through all the controls on the form and changing the RTB's that have been modified, your code is applying the new font to all the RTB's that have been modified, not the one that last had the focus!
If you insist on having multiple RTB's on the form that the user can edit and change the font on, you'll have to implement a flag on your form that holds a reference to the last RTB to have the focus. Handle the GotFocus event of all your RTB's and set this flag pointing to the one that got the focus. Then, in your button click event, you'll know which RTB had the focus last without having to iterate through all the controls on the form.

Thanks for the input. I was going to do that but thought it would be unecessary to have code for each control. Thought there might be a generic method I could use.
I appreciate your help

It is. You can have one handler function that handles the same event for mutiple controls. If you look in the "Windows Form Designer generated code" section, you'll see that things like the button click event get wired up with a statement like:
this.button1.Click += new System.EventHandler(this.button1_Click);
Well, if you have multiple buttons, you can point them all at one click handler if you need to handle all their clicks in the same code:
this.button1.Click += new System.EventHandler(this.button1_Click);
this.button2.Click += new System.EventHandler(this.button1_Click);
this.button3.Click += new System.EventHandler(this.button1_Click);
Notice, each one of these is an addition statement.

Just add a reference to System.Windows.Forms.dll to the project and you should be fine. (Right click on Project in Solution Explorer, click Add References, select System.Windows.Forms.dll in the listbox that comes up).

Thank you for your help. It works.
I have another question. In windows application I can write System.Console.WriteLine( "something" )
The program complies with no problems but the console never showup. Is there any solution?
Thank you

Are you sure you want a console to appear? Maybe you can make do with writing to the Trace?
In any case, the reverse of what you did the first time will solve your problem. Create a console application and copy/paste the form code in Main.

Here's the setup...I have 3 overlapping UserControls and I'd like for all but the last one to be fully transparent. My problem, however, is when I set the appropriate styles, etc., the transparency effect goes all the way through the controls and all I can see if the underlying Form. This obviously isn't what I want.
Think 3 Frames... event_frame, drag_frame, render_frame. The event_frame handles the simple mouse events, the drag_frame displays and dragging/drawing upon mouse movement, and the render_frame displays all the finialized objects.
So basically I'd like for the event & drag frame to be transparent, but for the effect to stop at the render_frame. Obviously I'm fairly new to C#, so if I've missed something basic I apologize.
And one other quick question...I was wondering if there was an effective way of Clearing a graphics object? And not like the current .Clear(Color.*) method. Is there some way in which to just dump the contents of the graphics object? This one has me stumped as well.
Yet any help or suggestions on where to find a good solution would be greatly appreciated, thanks!

And to add a note to my second question there...I've tried using the alpha bit set to 0
*.Clear(Color.FromArgb(0,Color.White));
and that simply produces and entirely black UserControl. Just thought I'd mention that as a way I've tried to 'transparently' .Clear() a graphics object...to no avail.

Can't you just set those properties on the form in the designer ?

Hi,
I am transforming an input XML documnet using XSL. I have a follg code to do that. The issue is that in my o/p XML, I have a few empty tag elements - When I test my xsl using XMLSPY, the o/p xml contains empty tag elements with short tags in it, which is desired (i.e. <mytag attrvalue="abc"/> ).
However, XML generated from C# code, has the empty tag elements with expanded end tag (i.e. <mytag attrvalue="abc"> </mytag>). This is not what I want.
Does anyone know how to tell C# code/class to create short end tags (i.e. singleton type). Below is my C# code:
public XmlDocument TransformXml(XmlDocument doc, string xslFile)
{
StringBuilder sb = new StringBuilder();
TextWriter tw = new StringWriter(sb);
XslTransform xsl = new XslTransform();
xsl.Load(xslFile); //load xsl file
xsl.Transform(doc, null, tw, null); //does transformation
XmlDocument ret = new XmlDocument();
ret.LoadXml(sb.ToString());
return ret;
}
Thanks,
Ken

what are the differences?

When you compile in debug mode, it creates debug information so that you can use the debugger. Also you get more information in the error messages.
---
b { font-weight: normal; }
|
|
|
|
|
|
Additionally to the debug information no optimizations are done.
Some optimizations would make it hard to debug your code (i.E. inlining, removal of unused variables, loop-unwinding etc.).
In release mode those optimizations make your program run faster (not always notable, depends on your design and what your program does.)

Hi,
I wanted from my server computer running XP, log off/lock a client machine found on my home network using C#. Is that possible? Give me some hints..
|
|

Off the top of my head...
You can set up a client/server application on the two machines respectively, and then send a certain message from the client program to the waiting server and depending on the message received have the server execute that particular command, whether it be shut down, log off, lock etc.
On the server to log off, shut down and junk, look into the windows api and pinvoke the needed functions to preform those operations. Off the top of my head to shut down is ExitWindowsEx, just poke around it shouldn't be hard to find.
But, once you log out remotely, you won't be able to log back in remotely. I don't think...

right thanks.. any one has an actual sample of a code of a form with a lock/unlock button on the client where i can log off or lock the client. Once i know how to do that locally, I should be able to do it remotely. thanks

Hi,
I have two Forms (A and B). When Form A is active I open Form B. I then want to run some code automatically in Form A when I close Form B. How do I do that?
Thanks,
