Glad you got it solved!
Yeah, you have had to do the same in every implementation, but there was these two reasons why I suggested BackgroundWorker:
- if I understood correctly, MethodInvoker shouldn't be used. If it's internal, it's not well documented and there are no quarantees for backward compatibility in future versions
- with BW the model is easier to implement and therefore also more understandable
But then again, are those valid reasons at all fully depend on your needs.
Happy coding

Your code works. I replaced the createMailBody with the string directly.
string strImage = "TestImage.gif";
string strTitle = "HTML File";
string strMailBody = @"<html><body> <table> <tr> <td><img src="$image$"/></td> <td> $title$</td> </tr> </table></body></html>";
strMailBody = strMailBody.Replace("$image$", strImage);
strMailBody = strMailBody.Replace("$title$", strTitle);
I assume the problem is that you don't get the right string from the createMailBody method.

Sorry for delay...
iam using this to send a mail. Problem is, at the receiver end image doesn't display. How to solve this?
|

The img src must be an absolute url or you can use attached images as described here[^].

I got a big Access database I'd like to convert to MS SQL Server 2005
and I'm looking for an efficient automated tool to convert data (over
1 400 tables), query, forms and interface.And i want to convert the access forms to C#
Does somebody can provide me with a list or, at least,a suggestion of
tools that has already been used or well known for their
efficiency.(except upsizing wizard and DTS, I tried with no success,
since I'm not a programmer)
Thanks,
Guy

you can move the tables over to sqlserver using SSIS. i dont know about the forms and interfaces tho. you might have to create those yourself
|
|
|
|
|
There's nothing that will convert the forms, or anything user interface, to C# or any other language. You'll have to recreate all of this yourself.

You can try:

but I haven't tried this myself.

Here is the code snippet, with Reflection code. I have taken the code for Reflection from below link
"http://www.codeproject.com/KB/cs/C__Reflection_Tutorial.aspx"
public bool SaveLoginInfo(string UserName, string Password)
{
if (objForDBTransactions == null)
{
objForDBTransactions = new RegMgr();
}
try
{
bool bSaveDone = false;
object[] ArrayParam = new object[] { UserName, Password, objForDBTransactions };
//=================================================================================================== <b>//Way 1: It is throwing an error - Object reference not set to the instance of the object</b> //Type Objtype = Type.GetType("Login");
//MethodInfo myMethodInfo = Objtype.GetMethod("Save<string>");
//myMethodInfo.Invoke(Objtype, ArrayParam);
//===================================================================================
<b>//Way 2: It is throwing an error - AddressBook.Login.Save does not exist</b>
Type ObjType = typeof(Login);
Object obj = Activator.CreateInstance(ObjType);
bSaveDone = (bool)ObjType.InvokeMember("Save <T>", BindingFlags.InvokeMethod, null, obj, ArrayParam);
// Tried with Save, Save<string>, Save<T> however none is working.
//=================================================================================================== return bSaveDone;
}
catch (Exception e)
{
System.Windows.Forms.MessageBox.Show(e.Message);
System.Windows.Forms.MessageBox.Show(e.Source);
return false;
}
}
Here is Save function of Login class
public bool Save <T>(T UserName, T Password, RegMgr objRegmgr)
{
this.UserName = UserName.ToString();
this.Password = Password.ToString();
objRegmgr.SaveLoginInfo(this);
return true;
}
Thanks in Advance

That article has a discussion board. Consider posting your question there with a neat subject.

Please go read the documentation on MSDN, and what they say you need to pass into that function. You havent, and hence the error.

Way 3:
bSaveDone = new Login().Save(UserName, Password, objForDBTransactions);
Have you actually sat down and thought about why you are using generics and reflection to achieve some very simple tasks?
|

Hi,
Thanks for the way3. I have already tried with that and that was working fine for me. The reason why I am using Reflection and Generics is because we gonna use these two concepts in our next project which still is in design phase. So just to learn I am using them.
Thanks for your efforts.
Thanks & Regards,
Puneet

Ok, in that case:
Generics in type specifications are usually done like so: Type`1[Generalisation] so like System.Collections.Generic.List`1[System.String].
I'd go out on a limb and suggest that Save`1[System.String] will work for you. Otherwise, you'll have to read the docs more.

Hi,
Thanks a lot sir. I will try your solution and will definately read some more stuff on Reflection and Generics.
Once again thanks for your efforts and time.

Puneet

Hai all,
In my application i am trying to convert my wmv file into swf file format. And its working on Command prombt very well and it created the output file also.
But when i write the code in c# (below mentioned) its not working. But no more errors or exceptions arise. But No outputs found(no new.swf file was created).
filargs = "ffmpeg -i d:\\hai.wmv -s 480*360 -deinterlace -ab 32 -r 15 -ar 22050 -ac 1 d:\\hai.swf";
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName ="D:\\ffmpeg\\ffmpeg.exe";
proc.StartInfo.Arguments = filargs;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = false;
proc.StartInfo.RedirectStandardOutput = false;
proc.Start();
proc.WaitforExit(50000);
Thanks and regards...

Dont do that!
Also provide a current working directory, else where would the output file end up?

Hi to all,
In MSVS 2008 Documentation, (System.Windows.Forms) Application.ThreadException Event there is an example how to handle unhandled exceptions using:
Application.ThreadException += new ThreadExceptionEventHandler...
and
AppDomain.CurrentDomain.UnhandledException +=
new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
But, there is a caution that says:
"Because this is a static event, you must detach your event handlers when your application is disposed, or memory leaks will result."
So, the problem is that I'm not sure WHERE to detach these handlers. If someone knows the answer, please share this knowledge with me!
Thank you in advance,
Matix

I haven't tried, but I think this will do the trick
Application.ThreadException += ThreadExceptionHandler;
Application.Run(new Form1());
Application.ThreadException -= ThreadExceptionHandler; Application.Run blocks until application exits.
|
|
|
|
|
In case that some kind of unexpected error occurs inside Form1, if program execution transfer to our Exception handler, and handler EXIT application (because some kind of fatal error has occurred), does program executes code after "Application.Run(new Form1());"???
|
|
|
|
|
Well, wrap it in a try finally blocks
Application.ThreadException += ThreadExceptionHandler;
try{
Application.Run(new Form1());
}
finally{
Application.ThreadException -= ThreadExceptionHandler;
}finally block will execute always.
|

I'm not sure that's needed -- if an exception is thrown by the app and not handled, it's going to hit your error handler anyway.
I may, of course, be wrong.
Cheers,
Vıkram.

Correct. But we were talking about detaching event handler when application ends. So I think finally is required.
|
|
|
|
|
The operating system is perfectly capable of cleaning up when your process exits.
Actually, .NET will already clean up all objects (including the event handler) when the AppDomain shuts down.
It only makes sense to explicitly detach the event handler when your application doesn't shut down but you still want to free the memory used by the exception handler.
