In the directory C:\Program Files\Microsoft Visual Studio .NET\Common7\Graphics\videos Microsoft put sample avi files. I think so people can use them in there applications.
I've search the web, but I can't find any C# example how to display search.avi on a form.
 Does any one know how this can be done?
Thanks,
Patrick

Not entirely sure. I know that MFC had a class called CAnimateCtrl which used the ActiveMovie control. This is still available in the COM tab of the component toolbox add/remove dialog so I'm sure you can use Interop to use that.
Worth a try!

Shaun,
It works with this control.
It's not exactly what I want. The search.avi needs to play in a loop and be transparent.
Thanks, I'll keep looking.

I have an assembly that is loaded by a .exe. The assembly is interested of knowing where is the application's exe is located on disc, in order to find its configuration file.
I would like to do this so the application can monitor the switches section to enable and disable tracing without restarting the application.

This will probably give you the current assembly and not the .exe, but this is what I use from within an .exe to find its location.
string path = System.IO.Path.GetDirectoryName( <br />
System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);<br />
path = path.Remove(0,6);
Perhaps changing GetExecutingAssembly() to GetCallingAssembly() would get you the results you need.

if you are housing your own exe in the path you want you can do this :
private void button8_Click(object sender, System.EventArgs e)
{
try
{
string s=Application.ExecutablePath.ToString();
MessageBox.Show("my .exe directory is:\n" + s);
}
catch
{
System.Exception f = new System.Exception();
MessageBox.Show(f.Message);
}
switch(twinsOnWay)
{
case ("twins on the way"):
MessageBox.Show("for mr and mrs dynamic","twins on the way");
break;

I am having a hard time trying to implent winforms gui event handling. I have an mdi application where the the child form displayed depends on what which linklabel or button the user clicks (there is more than one way in different parts of the app to reach the same form). I want to pass the name of the form to display. I am trying to separate the event handling from the form (is this good app architecture?). Here is what I have so far, I know I am missing something, but I don't know what is . Any help please?
//define delegate
public delegate void DisplayFormEventHandler(object sender, DisplayFormEventArgs e);
//create custom event
public class DisplayFormEventArgs : EventArgs
{
//Define and initialize two variables)
}
//handler to be executed when event fired
public class DisplayFormHandler
{
public void windowToDisplay(object sender, DisplayFormEventArgs e)
{
switch(componenetClicked)
case "Orders":
//code here
case "Settings":
}
}
//event sender
public class Home : System.Windows.Forms.Form
{
private void InitializeComponent()
{
LinkLabel newOrdersLink = new LinkLabel();
newOrdersLink.Click += new DisplayFormEventHandler();
}
}

When I programed in C, I use memcpy function to change a struct to a string.
Ex:
struct A
{
int x;
...
};
...
A a;
char str[50];
memcpy(str,&a,sizeof(A));
...
However, when I write in C#, I also want to convert a class/struct to string but I don't.
Can you help me?
Thanks

You can do it this way:
A aa = new A();
string myString = aa.x.ToString();

Thank you for your answer, but I want to convert a string to a class/struct because I write an application using Socket, Server module wrote in MFC 6.0 and client module I write in C#, data from Server send to Client are records which converted to string and pass throught metwork. Now, I want convert this data to struct/class after receive string data from server.
Please help me. It very importance for me.
Thanks.

Hi
Is this possible (in .NET RegEx)? Eg.
pat1 = (?<pat1>\w?(pat2)\d?)
pat2 = (?<pat2>\.?(pat3)\@?)
...
Thanks
|

|

try the regularexpression clas
using System.Text.RegularExpressions;
and then you can match with
Match m = Regex.Match(strText, @"(?\w?(pat2)\d?)", RegexOptions.IgnoreCase);
if (m.Succes)
{
string value = m.Groups[1].Value.ToString(); // like $1 in Perl
...
}
or
Regex.Replace(strTex, @"(?\w?(pat2)\d?)", @"<replacewith>", <regexoptions>)
If you come from Perl you don't need to break the / or \ (=~ /\// | =~ /\\/) but you need to "break" the " with double them
Regex.Match(strText, @"value=""(.*?)""\s*>", RegexOptions)
Hope this will help!

Thanx for the reply, but this is exactly what I dont want to do! 
There mite be a 100 sub patterns. A lexical analyzer can handle this easily, but is this possible in RegEx?

I have a WinForm app that is fine and dandy when executed as a simply local exe. I'd like to host it via a webserver (http://blahwebserver/MyApp/Myapp.exe). I've gotten through a few initial issues which brought to light some holes in exception handling, but I'm really running into a problem with the config file apparently not being loaded. I don't really know what to do about this or where to research on it, though I kinda hoped it would have been mentioned in here[^] but it wasn't. So I've got nothing at this point.

If you have ASP.NET running on the server, it might be blocking access to the .config file because of a bug in .NET 1.0.
Edit the machine.config* [edit]on the server[/edit] and change line 447 from
path="*.config"
to
path="web.config"
This will allow your app.config file to download but still block downloading of the web.config file.
[edit]*On my computer it is at: C:\WINDOWS\Microsoft.NET\Framework\v1.0.3705\CONFIG
If you have .NET 1.1 installed on the server then this change has already been made, but if you told IIS to use .NET 1.0 for that application (or for the whole server) then you still need to edit the machine.config[/edit]

Just found out that it is not a good idea to try and load 20k+ records into the standard DataGrid (windows.forms, not the asp one), takes ages and sucks memory - not a problem on my machine, but the users... 
Anyway, anyone got any ideas? I have been reading about virtual grids, sounds just what I am looking for, but have not been able to find a free/reasonably priced one.

Seems like 20K records in a grid would be hard to navigate to find anything. Isn't there some way you can filter that to bring the number down?
You can kind of build your own virtual grid out of the standard grid. It depends on how your data is stored.
In a program I have been working on, I wanted to be able to walk through the records one at a time regardless of the binding and control I was using. By making my own collection that provided ITypedList, I was able fetch the desired record in the indexer. Worked well with a range of databindings.

Does anyone know how I can accomplish this? I have a combo bo that I want to be active (the user can interact with it and select from the available options), but I don't want them to be able to edit the existing entries or type new values into it? Is this possible without writing my own combo box? I thought about just removing focus but then I don't think the user would be able to select from the existing items because it would never be able to get focus.
TIA,

How would you link a combo box to a list box. I have a table of products, and a table of categories, and these are linked the standard way. My combo box has a dropdown of the categories. I want the listbox to be populated with all items that have the same category as the one selected.
Any ideas?
