Why can't you do it on the level of keydown, keypress and keyup messages ?
Why can't you just detect a keydown and pass the focus to the control ?

Firstly, when a key is pressed, I need to add a char to the textbox, even if it does NOT have focus. Then, when I press a key, the keydown event is obviously not detected by the textbox. The same with the form! There is no info about this event. I could use PreviewKeyDown, but I couldn't mark the message as used/handled.
Secondly, the form should distribute the messages, not necessarily to the box. Maybe somewhere else, basing on other conditions.

Hi evry body.
I Have a Question about error in Asp.net with c#.
i get error " Unable to luanch the ASP.NET develpment server"
Please help me!!
thank you
|
|
|
|

Where to start...
1 - we HAVE an ASP.NET forum
2 - The error means the server can't launch, it's a setup problem, not a coding problem.
3 - based on what you've said there's little to no chance that anyone can help.
Why don't you copy and paste the actual error message, with all the details given, so we can try to work out what is going on ? What version of Visual Studio are you using ? I assume this happens when you press F5 ? Do you have IIS installed ( you don't need it, but it would be interesting to know if it works and the ASP.NET server doesn't.

I do not understand.
Please explain how setting the MultiColumn property to true will help the OP to check a CheckBox in theirCheckedListBox.

The OP has already indicated that they are trying to do this in code.

i am posting details of my code:
----------------------------------
private static string CALLURL(string url)
{
string Res = "";
try
{
HttpWebRequest gatewayReq; //Used for HTTP Request
HttpWebResponse gatewayRes; //Used for HTTP Response
gatewayReq = (HttpWebRequest)WebRequest.Create(url);
gatewayReq.Timeout = 60000;
gatewayReq.Method = "GET";
gatewayRes = (HttpWebResponse)gatewayReq.GetResponse();
Stream ReceiveStream = gatewayRes.GetResponseStream();
StreamReader sr = new StreamReader(ReceiveStream);//, System.Text.Encoding.ASCII);
Res = sr.ReadToEnd();
MessageBox.Show("message sent successfully.");
}
catch
{
//Res = "URL is not responding at the moment.";
//WriteErrorLog(DateTime.Now + "|" + "Call URL Function: " + ex.Message.ToString());
MessageBox.Show("Sorry,Unable to send Sms.Try Again Later.");
}
return Res;
}
private void send_Click(object sender, EventArgs e)
{
string url;
string msg;
Int64 no;
no = Convert.ToInt64(textBox1.Text);
msg = textBox2.Text;
url = "http://203.212.64.15/genericpushnew/pushsms.aspx?userid=demo123&password=hotmail01&masking=CVRTNP&mobileno=no&message=msg";
CALLURL(url);
}
}

Use this:
url = string.Format("http://203.212.64.15/genericpushnew/pushsms.aspx?userid=demo123&password=hotmail01&masking=CVRTNP&mobileno={0}&message={1}",
Convert.ToInt64(textBox1.Text), textBox2.Text);

Exactly what the OP is doing. Read a little closer before replying.

I'll try. Once you answer a number of questions, you're bound to make a mistake somewhere.

Hi,
Without seeing an example of the skupaj string it's difficult to be sure what is wrong but String.Split will not be producing empty strings. It is likely that the apparently empty strings contain either non-printing or white space characters and my guess would be line endings.

How empty is empty?

I added to application app.config file and can access it successfuly.
However after I copied the exe with app.config file to another machine it fails to read its settings returning null values string value = ConfigurationManager.AppSettings["MyValue"];
Also when I change from text editor app.config file on original machine used for project compilation, these values do not get updated when they are read from exe application.
Only when I change those values from VS in app.config file.
How exe locates its app.config file?

I am debugging a program that combines several wav files into one. This code always gives me an error message:
try
{
outFileStream = new FileStream(outputFile, FileMode.Create);
}
catch (Exception ex)
{
MessageBox.Show(ex.GetBaseException().ToString());
}
The error message is:
System.IO.IOException: The process cannot access the file 'C:\Documents and Settings\ .... \02.wav' because it is being used by another process.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, FileShare share, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy)
at System.IO.FileStream..ctor(String path, FileMode mode)
at LiveDescribe.WavFile.writeAudioFileHeader(String outputFile, Boolean pStereo) in C:\Documents and Settings\ .... \WavFile.cs:line 503
note: line 503 is the line outFileStream = new FileStream(...)
How can I make it work?
Thanks.

When you open like this
outFileStream = new FileStream(outputFile, FileMode.Create);
it will first delete the existing file(if any) and then create a new file.
I think the file is exclusively locked by some other process or the process itself where you are working on. This happens if you try to open a file without closing the file in previous occation.
Check your code, if some other process has left the file open so operating system cannot delete the file.

First, find what process is using the file. My best guess: it is your program.
Inside the try...catch block, add a using block:
try
{
using (outFileStream = new FileStream(outputFile, FileMode.Create))
{
...handle your file here...
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
What this does is ensure that the open file is fully closed and disposed before your app tries to open it again.
You may also want to replace the file mode with FileMode.OpenOrCreate

I have tried your solution (using ...) and it's still giving me the same error. Once it hits the using line it jumps to the catch exception line.
|
|
|
|

Then the file is genuinely in use by either another part of your app, or by another app.
Are you taking three files, reading them and then trying to overwrite the first one? Or outputing to a fresh file?
Try changing the output file to a new, fresh folder that nothing else will be using. Does this cure the problem?

I am taking a bunch of wav files and try to combine them by inserting smaller wav files into an original big wav file. (ie. I have a 45 min long wav file and I am trying to insert or merge 30sec long wav into that 45min wav file, outputting a new file where all wav files are merged.) The program uses file selection dialogue box so the user can choose where to save the output file. I tried saving the file in C:\ and no luck.
