Hello
Your question is a bit strange:
1- Your subject title is the name of the class you can use to do the task. What's your question?
2- You mentioned you are saving a file over a server? What about security?

Regards

at the moment the file is created in the asp.net/c# app by clicking a button and the xml file is saved to the root of the application
so i need to use a filedialog to give the client the option to save the file
as for security i have no experience of security so im afraid there is none for now anyway

Well, It'd be better if you show a treeview with the folders you want the user to be restricted to only, or make a textbox to write the relative path of the file to save. also you might want to check and validate the input in these fields before really creating the file on your server. Showing the entire folder tree of your server is like showing a "Hack me" dialog box!!

I aurge you to revise your security permissions, and other issues before allowing users to access and modify file system on your server.

how to disable border of a button

ok thank you for your help
i have found one way of doin it

private void SaveFileToDesktop(string fileName, string fullFilePath, string fileContentType)
{
//*** check if the file exists
if (File.Exists(fullFilePath))
{
//*** create new file and get length
FileInfo iFile = new FileInfo(fullFilePath);
long fileLength = iFile.Length;

//***
Response.Clear();
Response.ContentType = fileContentType;
Response.AddHeader("Content-Length", fileLength.ToString());
Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName);
Response.WriteFile(fullFilePath);
Response.End();
}
}

but i will also take alook at the security side of things and advice about where to start learning about security

For God's sake, stop reposting your question over and over again!! Mad | :mad:

This could be what? The tenth time you post the same question about rounded buttons?!! You've taken about a dozen answers in your older threads and now we are all ignoring you because of this very rude reposting!!

break statement

Hi,

I have a small question.

Suppose i have this code:

while(condition)
{
try
{
if(condition)
{
break;
}
}

catch(exception)
{
//code
}
}

Where would i be if the break statement is executed?

Im trying to get out the while statement. Im just not sure where the break statement would take me.

Thanks in advance!

According to MSDN the "break statement terminates the closest enclosing loop or switch statement in which it appears. Control is passed to the statement that follows the terminated statement, if any." So control is passed to the statement following your while-loop. Take a look at the MSDN topic[^]; they have an example similar to yours using a for-loop instead of the while-loop

Hi,

If you remember the folders name, try the search function of windows.

Search for *.sln if your new version exists, there will be a .sln file.

You can also verify it by checking last modified date of the files. Smile | :)

Strongly named dll

topcatalpha25-Sep-06 23:49

Hi,

I trying to use different Dll's in my project, more specific, strongly named and weakly named combined in the same project. But it seems that VS (C#) wants me to sign all the assembly's in the project with the key, before i can build the project.
Is there a way to combine third party weakly named with our strongly named dll's in one project?

I also tried a tool IlMerge to make a strongly named dll of a third party dll, but for some reason the program didn't want to add an assembly/key to it..

Thx

Kurt

What type of project is this? And when you say that you are trying to use different DLLs in your project do you mean you are adding references to them?

You can mix strongly named assemblies and 'weakly' named assemblies in your project references, we do it here, but there's a requirement for your assemblies to be strongly named if you want to put them in the GAC.

Regards,
Rob Philpott.

topcatalpha26-Sep-06 2:10

It's a C# windows application using Dll's added by reference, but also dynamically loaded (unmanaged), using reflection. We want to be sure that our project.dll is only used by our project.exe. and vice versa, the other third party dll's are not important.

So no one can replace the exe with his own exe or can replace the dll with his own dll.

For this we made the project.exe strongly named and doing this results in errors on third party Dll's because they are not signed with the key.

i suppose GAC is good for one way check, not both ways ????

Thx

Interesting,

So I guess the assertion is that if you sign an assembly all the assemblies it references must be signed as well. That can't be right??? I'll have to get my Jeffrey Richter book out for that one. Also, you can't use reflection on an unmanaged dll as there is no metadata in traditional DLLs to query. Do you mean interop?

Rob Philpott.

k, thx. ,looking forward to the result.

i guess this article uses reflection on unmanaged dll's ...

or i must have misunderstood the article???
