Not so easy, a few steps are involved. You need some event for deciding to change to your "edit" mode, e.g. a right mouse click on the control. Then, draw a rectangle around it or mark it otherwise. When you receive a mouse button down event on the border of that marked control, set a flag. Then observe the mouse move events and resize your control. When the mouse button is released, remove your flag. You may need to call Refresh() time and again for getting the things drawn nicely.

I think U have to maintain a configuration file with control default properties.,
when u need the default properties (old properties), read & set the properties from configuration file.

Okay, I think I got your question now.
Try this: Allow the User to Resize Controls at Runtime[^]. The code is in VB. But once you understand the concept you can write your own code to do that or you may convert it using the conversion tools available online.
Let me know if this is what you wanted.
And ya, I found the link using Google.

Hi,
I draw a rectangle over some text using solid brush. The content is invisible after drawing that rectangle. Is there any other brush which gives the transparency.

See here[^] for some samples on using the Opacity property.
It's time for a new signature.

Hi Experts,
I am trying to convert a VB application to C# .net. I came across an enum which contained values as
stsAvailabilityBits = &HF,<br />
stsFormAccessAllowed = &H1,<br />
stsValidUser = &H2,<br />
stsSystemAvailable = &H4,<br />
stsPermissionGranted = &H8,<br />
stsInquiryOnlyBits = &HF0,<br />
stsFormInquiryOnly = &H10,<br />
stsUserInquiryOnly = &H20,<br />
stsSystemInquiryOnly = &H40,<br />
stsRecordLocked = &H80,<br />
stsShutdownMinutesBase = &H100,<br />
stsShutdownMinutes = &HF00,<br />
stsErrorReturned = &H1000,<br />
stsFatalError = &H2000,<br />
stsTableEmpty = &H4000,<br />
stsResultsReturned = &H8000,<br />
stsParentControl = &H10000,<br />
stsLoadResultset = &H20000,<br />
stsSpecialPrivBitsReturned = &H40000,<br />
stsRecordAccessReturned = &H80000,<br />
stsTableLockRequested = &H100000,<br />
stsTableLockConflict = &H200000,<br />
stsMultipleLockConflict = &H400000,<br />
stsAvailBit23 = &H800000,<br />
stsUserCanExport = &H1000000,<br />
stsUserCanRename = &H2000000,<br />
stsUserCanReport = &H4000000,<br />
stsUserCanDelete = &H8000000,<br />
stsGetForInquiry = &H10000000,<br />
stsWebUser = &H20000000,<br />
stsAvailBit30 = &H40000000,<br />
stsAvailBit31 = &H80000000<br />
I am not able to understand what are these. I think they are hexadecimal values. If they are then how can i convert them into decimal/integer values in C#.net?
Please help!
Thanks!

Samar

try this code...
private string getDecodedKey(string strKey)
{
string strTemp = string.Empty;
string[] strSplitKey = strKey.Split(' ');
foreach (string strHex in strSplitKey)
{
try
{
int intVal = Convert.ToInt32(strHex, 16);
strTemp = strTemp + Char.ConvertFromUtf32(intVal);
}
catch
{
strTemp = strTemp + strHex + "GET DECODED KEY";
}
}
return strTemp;
}

Hi Ice,
I tried running your code with the value of strKey as "&HF" and it showed me the error
"Could not find any recognizable digits."
on this line of code
int intVal = Convert.ToInt32(strHex, 16);.
Am i doing anything wrong here?
Regards,
Samar

Hi Ice,
Your code was good except that i need to pass 0xF instead of &HF i.e. replacing &H with 0x.
Also i am not getting the proper value when i use the following code but when i comment the same then it was working fine.
strTemp = strTemp + Char.ConvertFromUtf32(intVal);
Can you please let me know why were you using the above lines of code??
Regards,
Samar

Hexadecimal, Decimal, Binary etc are representations, they're always good values.
Replace "&H" by "0x".

Hi Estys,
Estys wrote: Replace "&H" by "0x".
What am i suppose to do after replacing? Because even after replacing it wont be an integer or float or decimal, right?? Am i suppose to try and convert into an int or something after that??

(vb) &HFF = (c#) 0xFF = 255
The values are the same, it's just another way of representation.
The only thing that matters is the type of the variable.
So int myint = 0xFF; is perfectly legal.
The following lines are equivalent integer declaration / assigments:
int sixteen = 16;
int sixteen = 0x10;
This is a float :
float onetwethreefourfive = 123.45f;
So you don't need to convert the value, just replace the hex-prefix from &H to 0x.
In your case, some of the values cannot be assigned to int but must be assigned to uint or long, for instance 0x80000000.

Hey Estys,
I got it! Thanks a lot! Just one more question.
I have a textbox in which I am entering the data like "0xF". On click of a button i want to display its integer value. When i try the following code
Convert.ToInt32(txtHex.Text);
It is showing me "string not in correct format.".
What am i missing here?
Regards,
Samar

There :
(Convert.ToInt32(txtHex.Text, 16)).ToString();
I don't like my signature at all

That is good Estys. Thanks a million.

No it is not so good; it may preserve the value, however the readability is gone. These numbers look like special bit patterns, so they should remain in hex. All you need is a syntax change, from VB syntax (&H12) to C# syntax (0x12).
enum MyEnumType {
stsAvailabilityBits = 0xF,
stsFormAccessAllowed = 0x1,
...
}

either u can use escape sequence
like
char ch='\xFF';

Hi,
I am beginner to c#.net.
I am engaged in a project (part of HR Management), and i am stucked in a small problem.
The problem is, Leave is provided to employee. I have to display the leave statics of the employee in a manner show below
-------------------
| LEAVE | => this is dataGridView Header
-------------------
| USED | REMAINING | => this and remaining are dataGridVeiw cells.
-------------------
| | |
-------------------
| | |
-------------------
| | |
-------------------
| | |
-------------------
Thank you.

The DataGridView doesn't support cell merging natively. You have to custom draw the headers of the DGV yourself. Since you're a beginner, I don't know if this is going to help or even make sense to you, but there's a code example here[^].

By trying to use a grid with effectively 2 header rows I feel that you are overcomplicating things.
IMHO you would be better off by creating a custom control. Place a label on the control set its dock property to Top and Text to 'Leave'. Place a grid on the control set its dock property to fill. You can then use the grid as it was intended to be used and also have the added advantage that you can set the Font for 'Leave' independently from the font of the grid and even make the background for 'Leave' to be a pretty blue or green or whatever.
Just my 2 cents.
