how do i disable the close button in a windows form
This code was posted by me...
|
|
|
|
|
Set Form.ControlBox = false
(this also removes the Maximise, Minimise and system menu from the form).
You can disable the close box (grey it out, but leave the other info) by overriding the CreateParams method in your form:
protected override CreateParams CreateParams
{
get
{
CreateParams parms = base.CreateParams;
parms.ClassStyle |= 0x200;
return parms;
}
}

Hi every one.
there is a application that receives data from BTS stations and shows them as log in a grid...
In order to analyze the log,I need to access to the grid.I don't know how to access and read that?
in other words how can I read data shown in a third party application?

Hi,
you can interact with GUI parts in any app using Win32 calls such as EnumWindows, FindWindow, SendMessage and GetWindowText; it takes some knowledge of how Windows works and a lot of P/Invoke. If you haven't done this yet, you'll need to learn several new things. Use Google and look for some examples here on CodeProject.
My TrayIconBuster article does something related, although the goals are different.

All Controls are Windows themselves. And you will have to study, you can't solve your problem by asking 100 questions here.

ok....hmmm ... Could you please [give|refer] me some references for study?
Thank you.

I think perhaps this question is beyond the scope of the forum you have posted into. In order to access the information in the third party application you need to know how that application stores the data, including the structure of the windows used to display it. By enumerating all the windows belonging to the application you may be able to get to the simple text displays, but that will not guarantee you can understand the data as it is presented.
My suspicion is that you need to spend a lot of time learning the fudamentals of MS Windows before you can attempt to solve this problem. I would suggest reading anything (and everything) written by people like Mark Russinovich and Charles Petzold for a start.
good luck.

Hi,
Any straight forward way to produce a video from a series of images in C#?? You know, setting the frame and compression rates, I suppose DirectX can do that but couldn't find an answer..
Thank you guys.

Hi folks!
I have a strange behaviour I cannot explain, perhaps someone who's deep into 64bit development can enlighten me?
I have 2 applications written in C#: A main app (A) and an additional program for updates (U). When A is started and there's something to update, A starts U (using System.Diagnostics.Process) and quits. U in turn updates A's files and restarts A afterwards. So far, so simple. Worked for years (on 32bit Windows) without problems.
Now recently while doing some testing on Win7RC 64bit I discovered that the automatic update fails. When there's something to update, Windows tells me after a while that U doesn't work anymore and kills it (leaving an exception in Kernelbase.dll in the event log).
After some debugging I found that U hangs as soon as I try to show a non modal dialog containing at least one control (using new Form().Show(); showed the empty dialog OK and didn't hang). When I modified U's status dialog to add all controls inside its Load event and not already inside InitializeComponent(), the Updater hangs when I add the first control to the Form's Controls collection. 
A was compiled with x86 as target (because I need to use 32bit third-party COM objects) and U with AnyCPU (because it didn't have any specific external dependencies I thought it doesn't matter which processor architecture it's compiled for), thus running as 64bit application on a 64bit OS.
After switching U to x86 as well it worked, but I still don't know why!
With A being x86 and U being AnyCPU I can't even get a MessageBox to show (although the call to MessageBox.Show() doesn't hang the application).
Unfortunately I don't have the faintest idea what's going on here. Does anyone have a clue?
Thanks in advance,
mav

Ok, saying that my applications are behaving strangely would be more appropriate

You can use Refresh()
or use Event OnPaint()

Since when?
Every control has it's own Paint event.

Then use the PictureBox.Paint event - if you must use a picture box at all, rather than painting on the form directly. If you Google for "PictureBox.Paint" the first link is the MSDN example of how to paint on a picturebox[^]

C# repaint equivalent is Invalidate.

hi.i try delete all data in my database but database size not change.why?
please help me to resize my database.

Hi,
databases don't simply grow and shrink as you add or remove data; they will grow in rather large steps, and typically they only shrink when you give a command to compress the database; this reorganizes the entire data storage and may take a while.

Hi,
When I do request from web browser my cookies look like this:
Cookies/Login:
CLIENT_WIDTH_DIR=1276
CLIENT_WIDTH_DIR=250
CLIENT_WIDTH=250
MAIN_WIDTH_DIR=1066
MAIN_WIDTH_DIR=60
MAIN_WIDTH=60
PHPSESSID=cb49a7c6928e0cdd1892f2bdc0322173
But when I use the following code:
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "CLIENT_WIDTH_DIR=1276");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "CLIENT_WIDTH_DIR=250");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "CLIENT_WIDTH=250");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "MAIN_WIDTH_DIR=1066");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "MAIN_WIDTH_DIR=60");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "MAIN_WIDTH=60");
myHttpWebRequest.Headers.Add(HttpRequestHeader.Cookie, "PHPSESSID=cb49a7c6928e0cdd1892f2bdc0322173");
the cookies look like:
CLIENT_WIDTH_DIR
1276,CLIENT_WIDTH_DIR=250,CLIENT_WIDTH=250,MAIN_WIDTH_DIR=1066,MAIN_WIDTH_DIR=60,MAIN_WIDTH=60,PHPSESSID=cb49a7c6928e0cdd1892f2bdc0322173
2 lines, broken, instead of 7 and, of course, session id is wrong and nothing works.
How I can set the cookies right?
Thanks.
