hi
is there any wrong with this:
private void textBox1_KeyPress(object sender,
System.Windows.Forms.KeyPressEventArgs e) { int intKeyValue = (int)e.KeyChar; if (((intKeyValue<48 || intKeyValue>57 ) && intKeyValue!=46)) { e.Handled = true; } }

Hi Tamimi,
There is nothing wrong with that method.
In fact, thats the eventhandler i was trying to attach 'readIn' to.
If a key is pressed 'readIn' will call that eventhandler to check if its a valid one.
Sorry for the confusion Tamimi!

this.textBox1.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.textBox1_KeyPress);

Hi Tamimi,
Thats exactly what i meant. But i fixed that half an hour ago 
I do have another question...
If i want to get everything between 2 chars, how would i do that?
Example:
[1]
[12]
[123]
How would i get everything between the '[ ]' chars?
Substring wont help, coz the characters inside the [] can be sometimes 1, 3 or more.
Thanks in advance!

hi
try this:
int intStartIndex = textBox1.Text.IndexOf("[") + 1;
int intEndIndex = textBox1.Text.IndexOf("]") - 1;
string strBetween = textBox1.Text.Substring(intStartIndex,intEndIndex);
but you should be sure that the chars "[" and "]" are exists if not you will get an error index or something like this

You could also try using the textchanged event of the textbox.

Hi,
I have a radio button on my windows form and I want this to be databound to a binding source.
Ok, now it is very easy to set the CHECK State of the radio button to bound to a BIT data type of SQL. But what if I want to add some custom code for the CHECK STATE and the custom code uses the other type of data field from the SQL ? IS is possible ?
Example : I may have a varchar field in SQL which is named "fieldType". Now I want to add the following constraint,
Databound CheckState should be checked if(fieldType == "abc")
otherwise CheckState should be non Checked.
Thanks and regards

I am trying to reverse engineer my application to see the class diagram in visio. The reverse engineering succeeded but the visio file is empty. no diagrams in it.
Can anybody give me some helpful hints on that?

It may have created a visio model even though there are no diagrams. Check the model explorer window. You can create your diagrams yourseld by dragging the objects into a page.

Dear all,
I have add a listbox with following property on
listbox1.DrawMode=OwnerDrawVariable;
listbox1.HorizontalScrollbar=true;
listbox1.ScrollAlwaysVisible=true;
I am overriding the DrawItem event of the ListBox for drawing item's text. Some text are too big to fit in the list box. But the Horizontal Scrollbar is not enabled or working. Horizontal scrollbar is visible and [disable or dim]. Vertical scrollbar is working fine.
Please help.

when we have a project of c# consisting of many subprojects.....
subproject B is dependent on subproject A
if we build the subproject A and then build subproject B the subproject A is not again built............whereas if we build subproject B first then subproject A is also built
how c# compiler manages this.......where this information is stored that subproject A has already been built
|

Hi,
From what you said i understand that you have several projects in the same solution. To build the entire solution with all the project you can use the Build->Rebuild Solution option. If you want to build all the projects from your solution when you hit the build shortcut key try entering in the Configuration Manager and see if all project are checked for building.
Do your best to be the best

thanks sir but my question is
while building project that has subprojects the compiler keeps record of the subprojects that have been built it does not rebuild them...........i want to know where this information is actually stored.if a subproject is built and then we built another subproject that is dependent on it the compiler didnt rebuild the previous one it means that the compiler keeps some record of it i want to know where this record is maintained................which file the compiler uses to maintain this info.......to make it clear what i want to say consider
three subprojects A,B,C in a project........B & C are dependent on A..........from the right panel where all subprojects and files are listed we right click project B and build it.......in the progress bar we will see two build succeded......A is also built as B is dependent on it......then when we build C in the same manner this time only C is built not A .......it means the compiler keeps track of this.........i want to know where this information is stored.......
