You could use regular expressions in order to match the tags you want removed, and then simply replace them with string.Empty.
For instance, if you want to find a tag, you could use the <img [^>]*?> regular expression:
Regex r;<br />
Match m;<br />
<br />
r = new Regex(@"<img [^>]*?>",<br />
RegexOptions.Singleline | RegexOptions.IgnoreCase);<br />
<br />
for (m = r.Match(WebResult); m.Success; m = m.NextMatch())<br />
{<br />
WebResult = WebResult.Replace(m.Groups[0].ToString(), "");<br />
}
You can also group matches into groups, so for instance if you have a <a ...> linked text </a>, you could use <a [^>]*?>(?<1>.*?)</a> regular expression, that will replace the whole match of the regular expression with the group 1 text (that is the linked Text in the exemple), like:
r = new Regex(@"<a [^>]*?>(?<1>.*?)</a>",<br />
RegexOptions.Singleline | RegexOptions.IgnoreCase);<br />
<br />
for (m = r.Match(WebResult); m.Success; m = m.NextMatch())<br />
{<br />
WebResult = WebResult.Replace(m.Groups[0].ToString(), m.Groups[1].ToString());<br />
}
You can use RegexBuddy[^] to construct oyur regular expressions. It has a 30 perdiod evaluation and it's really easy to use it, because it explains every element and what it does. You can also test your regex. I also recommend a Regular Expressions Tutorial[^]. You fill find regular expressions to be really usefull in other situations as well, and they are also faster than any string parsing code you will write.

Are you talking about Office 2000/Office XP? (the Office you are trying to automate)
Or Windows 2000/Windows XP? (the OS on which you run your program, also which versions of Office are installed on each of them?)

Hi
There are some mp3 files with their text, i want to set it ,when a sentence
of mp3 is heard , in parallel i can set exactly that sentence show as a text.
How could i sync these together?
|
|
|
|
|
Your program should be able to get the playtime and depending on it you show the apropriate text. For instance if your playtime for your mp3 is at 1'30" you should show the text that coresponds to the the one spoken at that particular time.
It's an approach that subtitles for movies use.

Mircea

thanks , but i dont think it could be possible , because i have many mp3 files and many text for them , so it waste many times.
C# couldnt receive any argument from Mp3 files?(like flash object that could send argument to C#)
|
|
|
|
|
There is nothing in the MP3 file that says "place your text here", so there is nothing to get from the MP3 file. You'll have to put the text together yourself and figure out the timing by hand. The MP3 won't have any information to do this automatically.

I have some code that I need to include in my project. The code is organized in a directory structure, such as:
Directory1 - Directory2 - Directory3 - Lots of C# files.
- Directory4 - Lots of other C# files
I right click on the project, and select Add Existing Items, but it would not retain the directory structure, all files are added to the project directory.
If I want to retain the directory structure, the only thing I can do is to manually create a directory structure as the structure of the external code. Go to each directory and import the files in the corresponding directory of the external code.
Its the same for both Visual Studio 2003 and 2005.
Is there a better way to do it ? Or let me rephrase my question, what would be the best way to include a whole external directory structure to your project ?
Thanks for your help.

In VS2005 there is a sample macro called "GenerateSlnFolderOnDirStructure" that should help you. Open the macro-explorer (Alt+F8 or in mainmenu Extras--Macros--MacroExplorer) and run the macro by double-click.

You can also copy / move them to the solution's folder and then click "Show All Files" and then select the root folders and "Include in Project". Voila
As of how to accomplish this I wouldn't have a clue at the moment and I'm too lazy to google it

Hi All,
I have a SQL Server at my office. I can VPN into the office from home in order to access the server. I have a program that makes a connection to this server when it loads up. I do this in a thread, but for the sake of this message I actually put this code in the _Load portion of my app (just to take the delegates, etc, out of the equation). I have a worker thread that checks the connection as well and updates a label to tell you if you are connected or not. If the worker thread detects it is not connected, it will try to re-connect. If I VPN into the office, and then run the app, it works fine. If I disconnect (after I've run the program and connected for the first time) the app does what it should and tells me that I'm disconnected. If I then VPN back in, after a few seconds the label is updated and it says the connection is restored.
The problem that I am facing is that if I am not VPN'd into my office (ie, it cannot see the server from the beginning) it will NEVER connect. It just keeps erroring out in the catch block and the message is that the connection could not be established. I have tried switching the Data Source over to an IP address just to be sure that it was not the DNS resolving that was messing up, and that does not work either. I have tried putting a Thread.Sleep(5000) in the Catch block upon failure just in case I was bombarding the server with too much, that does not work either. I cannot figure out what the problem is. I've done a bunch of different tries at it (ie, redo the connection string each try on the while loop and call Dispose()) ... nothing works. If anyone knows what my problem is I would appreciate a helping hand.
Here's what the code looks like in a nutshell.
while (!bConnectedToServer)
{
myConnectionString = "Initial Catalog=PROGARCHIVE;Data Source=192.1.1.20;User ID=test;Password=test;Connection Timeout=5;";
myConnection = new SqlConnection(myConnectionString);
try
{
myConnection.Open();
bConnectedToServer = true;
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
myConnection.Dispose();
Thread.Sleep(5000); //I've tried it with various values and none at all
}
}
I have also tried something of the nature:
myConnectionString = "Initial Catalog=PROGARCHIVE;Data Source=192.1.1.20;User ID=test;Password=test;Connection Timeout=5;";
myConnection = new SqlConnection(myConnectionString);
while (!bConnectedToServer)
{
try
{
myConnection.Open();
bConnectedToServer = true;
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
Thread.Sleep(5000); //I've tried it with various values and none at all
}
}

hi,
I also had a similar problem some days ago. I was not able to connect to my network database through Sqlclient. I just changed the SqlClient and put there Oledb. All is working fine now. If you can do it, just give it a try.
Hope it works in ur case also.
I think there is some problem in SqlClient, when it comes to access the database over a LAN. MS should look into it (my perception ofcourse !)
PS:
Caution !!!! You will have to change the SqlConnection, SqlCommand and all other object to OledbConnection and all ..... Also rebuild the connection string using the Oledb Provider.

Perhaps there was a problem with your network. I've never had a problem connecting over a LAN or through VPN connections.

Out of curiosity, what happens when you remove the Connection Timeout=5 from the connection string. The default, if not specified, is 15 second to allow the connection to be established, but you are telling it to give up after only 5.
|
|
|
|
|
I never even thought to play with that value at all...
Anyhow, I removed that line and it works now!
The only thing that I am curious about is that when this scenario happens (I am not VPN'd in, I run the program, it cannot connect right away and then I VPN in) ... It will take it about 60-120 seconds to finally make that connection. I put a MessageBox.Show() in the Catch block of the attempt to connect, and it will pop up 5 to 10 times saying "Could not connect...blah blah". But I've run it 30 or 40 times now and it always connects it just takes a lot of failures before it finally does.
Thanks a ton for the input!

Hi i have a custom control and everything is working fine, except in my test project when i compile it the settings of the control revert back to the default settings, why are my settings not persisting, and how do i go about fixing this problem?
Thank you,
|
|
|
|

Hello Tyrus,
Are you talking about property settings during design time?
If yes, it's possible if you are using the "DefaultValue" attribute at your custom properties.
Don't forget to init your class variables correct.
All the best,
Martin
|
|
|
|

well all my variables are initialized correctly to start with and then ill go in and change settings and stuff compile and then they dissapear and revert back to the original settings, and it doesn't happen every time i compile either it seems to be somewhat sporadic. i also am getting some wierd tasks telling me that there is object reference not set to an object or somehting like that.
|
|
|
|
|
It seems that you are using an object in your constructor, property or an eventhandler which is not "living" yet. So you get an null reference exception even at design time. Thats because the constructor of youre custom control is called when you compile your project.
If you whant you can mail me the controls code or post it.
All the best,
Martin

HI,
I have windows servcie application developed with VS2005 and running on Windows server 2003. It runs in debug mode perfectly. But when I run it in release mode I get follwoing error:
"An unhandled exception ('System.IO.IOException') occurred in VentFSWatcher.exe [560]. Just-In-Time debugging this exception failed with the following error: Debugger could not be started because no user is logged on."
I am running this servcie under NTAuthority/Local Servcice account and this acount has been granted permission on al relevant folder. How to find what is the cause of the error. In debug mode I can attach this process and step through but in release mode I do not know how to find error. This windows servic
Code looks like follow:
if(file.Exists)
{
lock(m_SynLock)
{
file.MoveTo(pathToMove);
}
}
You help is valuble.

Hi,
Try this ...
Goto Project Properties -> Compile -> Advance Compiler Setting and uncheck the Enable optimizations check box if it is checked !
I also was not able to attach to windows service in VS 2005 some days ago. I did the above told thing and it worked fine !
Hope it works in ur case !

Hi,
Thank you for the suggestion. I was able to solve the problme. It was related to File creation and File Move operations occuring at about the same time. By inserting Thread.Sleep() function I solved the problme. Also I inserted Try Catch block and writing to error log file I could see where and what type of error ocurred duiring execution.
Thank you.

1. Create a new project
2. Place a tablControl on the form
3. Place a listView on a tabPage of the tabControl, Dock it, set BorderStyle to None and set its backColor to Red.
4. Set Padding property of the tabPage the listView was placed on (tabPage not tabControl) to 0 (All).
5. Run the project and you'll see it's not filling the tabPage completely from the left (it's ok from the right side).
How can I fix that?
Your help is greatly appreciated.

Hello All,
I was wondering if anybody had any experience with PDF creation in c#. I am working on a project where we have had a request to add the ability to export the output of our project (basic 2d line plots, graphics, text) to a PDF. I have seen a number of 3rd party components that advertise being able to create PDF's, and I suppose Adobe has something as well. The general price range seems to be about $100, which I don't mind paying for something that works and is easy to use. I am not trying to convert anything into a PDF (some packages seem to be advertising this feature), but create the PDF directly, and populate it with some graphics.
Anything out there that exposes a Graphics object that represents a PDF page that I could just draw to with the code I already have in place for printing?
Any advice?
Thanks!
Aaron
