Hi,
I've creared a form with tabcontrol,
in one tab i put a richtextbox.
how can i access the richtextbox and edit a text in it?
Thanks

richTextBox1.Text="I got you";
you can access any control in form or any container control(if subcontrol is added by current form) by using its Name property. If Name is "richTextBox1" then just write
richTextBox1 and rest depends on you...

Hi,
If the Rich Text Box is the first control inside the tabpage, then there are two ways you can acheive this:
Directly access the RTB:
tabControl1.SelectedTab.Controls[0].Text = "I have just accessed my Rich Text Box and put text in it";
OR:
RichTextBox rtb = tabControl1.SelectedTab.Controls[0] as RichTextBox;
rtb.Text = "I have just accessed my Rich Text Box and put text in it";
I'll explain the above code a little:
First, we access the tabControl, and say, "we need to look inside the Selected Tab", then we say goto Control[0] (0 being the very first control inside the selected tabpage). Then we use .Text to access the Text property of the RichTextBox control and write something in it.
Note: If the RichTextBox control is NOT the first control inside your TabPage, then you will need to replace the number [0] with the appropriate number. I.e. If the RTB is the second control in your tabpage then replace [0] with [1].
I hope this has helped.

Why on earth would one use an array index to refer to a Control of which one has a perfectly good reference variable anyway?
This is a terrible suggestion, it weakens the robustness of the code as it introduces an unnecessary constant, that obfuscates the real intent and might accidentally change when the app gets modified and controls get added or removed.

Hey there 
I'm experiencing a little problem over here... In NotePad, when the scrollbars are visible I can use my middle mouse button to scroll horizontally or vertically, but when I create my own Text Editor in C#, this does not work. I can see for a split second the circular scroller thing appear but then it dissappears right away. Does anybody know a way to fix this?

make sure textbox has focus as well as middle mouse is not pressed

Thank you for your reply. I think I understand what you meant. I just went and made a change. I added textBox1.Focus(); to the code when I create the TextBox. but it still doesn't work. Do you know what causes this problem?

Hello
I have an ImageMap created using YDreams ImageMapDemo 2.0. I'm using this control for the rollover image effect with circle and polygons hotspots. My issue is I can't seem to figure out how to write the correct C# code for each hotspot. I am able to get one hotspot to have the rollover effect but not the other 4. Can someone please help me out with the code behind. I am very very new with C+. Anyone's help would be much appreciated. Been banging my head for 2 months.
Thanks in advanced

It would seem to me that you should be asking this, or at least you stand a better chance of an answer, if you had asked it in the Web Development or ASP Forums

Hi All,
I've been able to change the colour of a dateTimePicker inherited field by overriding the backColor method and looking for the WM_ERASEBKGND message in wncProc.
I also want to change the font colour of the dateTimePicker. I thought I could do this by overriding the foreColor method similar to how I did for the backColor. I can't find the message/hex bumber to look for within wncProc.
Is there any such message for ForeColor? Any help/ideas on this would be great.
Thanks,
Mel

I've got the same problem. Does anyone knows how to change the forecolor?

Hi All,
I have disabled a checkbox however when it's disabled I don't want it to be grayed out I want it to have it's enabled appearance. So instead of gray I whan it to be white.
Unlike TextBoxes when I use the following code the surrounding area of the checkbox and it's text change colour instead of the inside of the checkbox:
oCheckBox.BackColor = Color.White;
Does anyone know how I would go about doing this?
Thanks,
Mel

I dont think its possible unless you draw your own image on it but thats not good way. However, you can make your own CB using a Button and a Label. Change button background image or color on MouseEnter, MouseLeave, MouseDown and MouseUp.

Hi xman
thanks for the idea. Are you suggesting that I make the button appear to look like a checkbox and go from there?
Thanks,
Mel
