Another problem I have encountered is using a timer in .NETCF. The start and stop methods are not available. I just want a timer to count 40 seconds, and at the end of 40 seconds, throw an error message. I feel like im crippled trying to use the CF....

I'm trying to make a progress bar using the COmpact Framework for a Pocket PC. However, in the Compact Framework, there is no step property, nor is there a performstep method. Does anyone have an example of a working progress bar using the Compact Framework?.
I just want it to float indepenently at the front of my application. Also, a messagebox of some sort with moving ... 's would be acceptable as well, but I don't know how to code it either.

The ProgressBar Class[^] is supported under the .NET Compact Framework, however if you are trying to write your own ProgressBar control, you will have to write your own methods and properties. The PerformStep method under the .NET Framework only calls the Increment method passing the step value. The Increment method increments the value to itself, checks to see if it is within bounds and updates the UI.

Hy everyone!
I do want to split strings to get some special infos.
Lets say I want to split the following:
Winter, John\r\nBusinessnum. 1: +12 (23) 4567890\r\nMobile 1: +23 (456) 22562
Well I could get along with it using
string ltemp=""; // info is draged in here (e.g. the string above)
// remove characters a-z,A-Z and ,
ltemp=Regex.Replace(ltemp, @"[a-zA-z,]","");
//replace the + sign and replace it with 00
ltemp=Regex.Replace(ltemp, @"[+]",lreplaceplus);
// removes the /,(,),-,\r and \n signs or escapechars respectivly
ltemp=Regex.Replace(ltemp, @"[/()\-\r\n ]","");
After this my string looks like this:
. 1: 0012234567890:002345622562
Well now I do want to extract the 0012234567890 and 002345622562 in two seperate fields. Well I will take care of this later. At the moment I was trying to find out, what a regular expression has to look
1) removing the string in the beginning (meaning ". 1:") or any similar strings which might appear somewhere inbetween (meaning strings like this instead of just the ":"
2) extracting the first number (0012234567890) and the starting over at the next one, meaning I do want to do a loop similar to
while string not empty
parse it with regular expressions
store an extracted number in an array to collect them all
This means my aim is to get the following (explained with the string above)
stringarray[1]=0012234567890
stringarray[2]=002345622562
stringarray[3]= ......
If you might have wondered, yes the string above is a contact item of Outlook being an array of strings or a string respectively. And my aim is to pares this string, eliminating everything that's no (telephone)number and copying them in an array collecting the numbers in this string for furter use.
But well, as I described above I was able to eliminate almost everything except the numbers, but I was not able to remove the "separationstring" (the ". 1:" in the example above) and split the numbers apart.
Does anyone of you know any solution what my regular expression has to look like to solve my problem (because I guess an regular expression is easier, because otherwise my array would contain an empty field, if I split it bevor parsing it, e.g. if it was only text and no number).
Another solution which I was thinking about was to split the preparsed string, place it into the array and do the final parsing in accessing the arrayfields instead of the local string variable.
But at the moment I do not know which might be easier or if my solution, which I did so far, is already complicating the whole thing.
Thanks!
Stephan.

If the phone numbers are always in the format of your example, the following should work:
<br />
string s = @"Winter, John\r\nBusinessnum. 1: +12 (23) 4567890\r\nMobile 1: +23 (456) 22562";<br />
Match m = Regex.Match(s, @"\+(\d+)\s*\((\d+)\)\s*(\d+)");<br />
while (m.Success) <br />
{<br />
Console.WriteLine(m.Groups[1].Value + m.Groups[2].Value + m.Groups[3].Value);<br />
m = m.NextMatch();<br />
}<br />
Output:
12234567890
2345622562

Thanks for the example!
I tried to "copy" the result into a TextBox.Text instead of the Console.Writeln, but there was no result displayed.
Well actually when I will start parsing the string I do not know what it will look like! The string above is just an example!
It could even look like this:
Winter, John\r\nMobile 1: +23 (456) 22562\r\nMobile 2: +23 (456) 22563
besides I have to replace the "+" by a predifined string, which finally should be selectable in the Options. At the moment I do want to replace this by "00". And another change which might effect the example: My parsing should be able to parse the string no matter if it's fieldnames are German, English, French or whatever, but as far as I understood, this does not matter.
Well I guess I have to adapt the algortihm above so it also works with
Winter, John\r\nMobile 1: +23(456) 22562
meaning it should work with no matter how many telephonenumbers might be in the string. That's why I didn't try to use a "kind of fixed string" like yours. But maybe it will work too.
My problem actually is I do not have to just display the numbers on screen, I do have to save them somewhere. Because if the string which has to be parsed just contains one number, than it's the number the user (of my proggy) will work on with. But if there are more than one, I have to create a kind of popup for the user choosing one of the numbers. So I have to store them in a kind of array, because as I mentioned earlier I do not know how many numbers are in the string when starting to parse. In your example I do throw the string away after displaying, but well, I have to save it. Maybe that's a little more difficult, because it didn't work replacing Console.Writeln by TextBox.Text and doing a cast to string.

Anyone know how i can change the font size on a SysListView32?
I currently have the hwnd of the window and have tried using the following statements:
System.Drawing.Font f = new System.Drawing.Font("Arial",20);
SendMessage(hwnd,WM_SETFONT,0,f.ToHfont());
Any Sugestions?
Thanks in advance

This works for me:
private int WM_SETFONT = 0x0030;
[DllImport("user32.dll")]
static extern IntPtr SendMessage(IntPtr hWnd, int Msg,
IntPtr wParam, bool lParam);
Font f = new Font("Arial Black", 12);
IntPtr hFont = f.ToHfont();
SendMessage(view.Handle, WM_SETFONT, hFont, true);

Thanks very much Nick
It works a treat, I was just using the wrong overload SendMessage.

MSN Messenger uses a SysListView32, you should send that code to it. That would be intersting...

Are you sure you want to?  Looks like it needs quite a bit of refactoring, starting with the basics like having a more descriptive function name than "main()". It might make more sense to identify exactly what you want to do and just write it in C#. It'll probably be simpler, clearer and smaller.
By the way, if you want to persist along the line of getting someone else to write it for you, without even saying what it is or how it should work (or is that top-secret classified information on a need-to-know basis only?)  , you should at least repost the code, but make sure to check the "Do not treat <'s as HTML tags" checkbox, so that all the code shows up. Also, use the code tag or the pre tag around your code and it'll be more readable.

Hi guys,
How can we find a path of an exe using it's name?? The exe is some third party exe and can be anywhere in the system. How can I find the path?? MY requirement is to start this exe from my Service. Can any body help me with some code snippet? It's very urgent.
Regards,
Satya.

There is no general way to do this.
Usually an application that can be installed anywhere will create a registry entry holding the installation path. Take a look at HKLM\Software, you might be lucky and find an entry for your third party exe.
Other than this you'd have to scan the hard discs of the target computer, which usually isn't feasible.
Or you ask the user during installation by presenting a file open box with the exe filename as filter and then store the path in your configuration.

mav

Hi,
Do you have any code snippet for finding the exe using Registry method.
If you have please give me, it's very urgent and I can't make much trails now.

satya

As I stated before, there's no way for me to know where (if at all) the third-party program might store its installation path.
Open RegEdit and browse HKLM\Software\<name of the third-party company>\<name of third-party program> if it exists and perhaps you'll find a matching entry.
If you found such an entry you can access it from your service using the Microsoft.Win32.Registry and Microsoft.Win32.RegistryKey classes.

mav

If it is a program in the path, then you can use the SearchPath() API function (I'm not sure if there is an analog somewere in the .net library; you'll have to look for it and if you don't find it, just do a little DllImport).
If it isn't in the path, then you need to do a little of your own research to determine what's the best way to find it. As mav has suggested, it may be in the registry, but its exact location can be arbitrary, of course, so you need to do a bit of research on the particular application you are dealing with (i.e. use RegEdit).

Dear DotNet gurus,
I want to build a custom browser that is capable of capturing GET and POST requests (along with headers)for one of my class projects.
I use the Microsoft Web Browser component to do the same. I register events like NavigateComplete2, BeforeNavigate2 and DownloadComplete but none of them provide me with complete POST headers.
The "header" member just provides "Content-Type: application/x-www-form-urlencoded"
I have tried really hard but am dissapointed because i couldn't figure out a way to capture the POST headers.
I would really really appreciate if someone could tell me a way i can figure out the POST headers.
A solution using event handlers, or even something/someway of reading the raw socket will be of great help.
Please help me.
Thank you
Ranu

I am creating an application for invoice printing and also data collection.
I created a form for the user to input all the data.
It basically save all the information that the user had input, and then print the invoice of it.
I only know that there are two ways of doing this. Creating the print out by coding, or with crystal report.
I just confused on choosing which one to use, since I am a newbie in C#.
Does anyone have any opinion or idea?
Thank you very much in advance.
