its a good idea to check the object browser before posting, in this case the TabControl exposes a public property named "SelectedTab"

But in the Object Browser is not quoted which event occurs when I go from one tab pane to another tab pane..?? - and I also did not find a background property for the tab pane?

Yes, there is. It's called SelectedIndexChanged.

pat270881 wrote:

That's because there isn't one. Changing the background color of the Tab pane isn't supported by the default implementation. You'll have to owner draw the TabControl in order to change the background color of a single pane.

Okay, i have built a wonderful, slick application that is a deep, convoluted call-tracking system of sorts. There is an approval process built in, that uses email addresses to identify the approvers.

the problem is, there are required approvers that exist in multiple places, resulting in some people being listed more than once.

Essentially, here is what i have been running into. the names are strung together like this:

user1*user2*user3*user4

except sometines, you end up with
user1*user2*user3*user4*user2*user1

what i have been killing myself over, is trying to make a quick function that would look at this list, say "we already have user's 1 and 2, so only list them once".

I spent 4 hours on this yesterday, and ended up with an extremely complicated way to turn "user1*user2*user3*user4*user2*user1"

into
user1
user2
user3
user4
user2
user1

which, of course, can be done with 3 or 4 lines of code, not the 50 something i made yesterday. any ideas?

You mean something like:

String strUserList = "user1*user2*user3*user4*user2*user1";
char[] sep = {'*'};
Array a = strUserList.Split(sep);

(written without a compiler, so might not be syntactially perfect..)

ArrayList?

ArrayList list = new ArrayList();
foreach(string str in mySplitArray)
{
  if(!list.contains(str))
    list.add(str);
}

a very simple way would be to use nested for loops

quick pseudocode:

for (a=0..size)
  for (b=0..size)
    if array[a] == array[b]
      array[b]=""
    endif
  endfor
endfor

then just check for, and ignore empty strings

problem with measureString in textBox

shimritb13-Oct-04 3:40

Hi,
I'm having problems with the measureString function. I am trying to measure the length of a string the user types into a text box. However, the size in pixels that this function returns is different than what is displayed on screen. This causes a visual overflow from the text box rectangle for some inputs.

I've tried using measureCharacterRanges instead and the same problem still arises. A partial solution is supplied by using the function getTextExtentPoint32. Using getTextExtentPoint32 no input overflows, but some inputs are truncated before the end of the text box.

Do you know of any other function that will supply a full solution?

Thanks,
Shimrit

Form Causesvalidation property

Hello,
Iam new to c#
My Problem is something like this.

Create a sample windows application, having 2 textboxes & a command
button
Set the forms controlbox property to True

Write validation event for the 2 textboxes

private void txtpassword_Validating(object sender,System.ComponentModel.CancelEventArgs e)
if (txtempno.Text=="" | txtpassword.Text=="")
{
MessageBox.Show("Please Enter User Id and password","Invalid Data",MessageBoxButtons.OKCancel);
e.Cancel = true;
}

while running the application when the user clicks the button1
the focus is still in 1 of the textboxes, the validation event of the textboxes still fire.

Same is the case when the user clicks the X button on the control box.

i.e validation event is fired and form is not closed

Form Causesvalidation property aslo set flase.

if i write the code in the Form1_closing event then also the problem is not being solved.

This is because the validation event of the textboxes is fired first so the execution never reaches the Form1_closing event.

i need to provide this funcationality in my application,How can i do this?

Not a 100% sure this will solve your problem, as I dont really understand the question, but just in case its a simple as:

boolean or ||
bitwise or |

if (txtempno.Text=="" | txtpassword.Text=="")

should read

if (txtempno.Text=="" || txtpassword.Text=="")

Hello All,

I have developed some custom contorls for extra functionality such as MyTextBox inherited by TextBox and few others. But whenever i shift the project to some other machine, Forms containing those texboxes either doesn't open showing 'Designer error' or if they openn they dosnt display those controls at design time. (if i run the application it works fine but at design times it misbehaves)

Any Solution?

Thanx in Advance

sorry for my bad English.

Try to add reference to System.Design.dll... this lib doesn't shows on Visual Studio when you go to Add Reference. So you must to browse it on Framework folder

C++ and MFC -> .net and C# advice

I've been developing in C++/MFC for around 8 years, and we've decided to finally bite the bullet and upgrade from Dev Studio for VC++6 to the upcoming VS 2005, get to grip with .net and look at C#.

I need to get up to speed fairly quickly, so I make recommendations on where we go and how, so I'm after some material (a book probably) that will lead me along this route.

Can anybody recommend a good book, or even a set of tutorials aimed at my situation?

Thanks,

Mike.

If you are in a hurry, but still want to make a firm grounding in C# and .NET just buy these three books and start reading... The last one is more suited as a reference than as a start to end read...
