Hi
I have a C# application that uses Crystal Reports 10. I developed a setup project with Visual Studio.

For the Crystal Reports, I added the CrystalReports merge module to the setup.

When installing version 1.0 of my softare, everything works fine. The appliation and the Crystal Reports are installed on the target machine.

Now I have to deploy version 1.1 of the application. When I first remove version 1.0 and then install version 1.1 still everything is fine.

But when I don't uninstall 1.0 first and install version 1.1, the new version of my application is installed, but the Crystal Report dll's are removed from the system! Frown | :(

Any idea why it removes the Crystal dll's when I update?

thanx

simply you cannot.

You can't. As there is nothing you could use that address for in safe mode, there is no reason to have the functionality to get it in safe mode.

How do you plan to use it?

Changed unsafe to safe in my post, as that was what I meant.

I assume you actually mean the opposite... Confused | :confused:

Hello everyone! Big Grin | :-D

OK, I read and re-read this code like a thrillion times and I can't understand why it's doing this... Please check it out: (VS.NET 2003 solution file)

http://www.sulfurmidis.com/BeepXtreme-srchelp.zip
[^]
OK. When I click on the open button, (File>Open), it's suppossed to make a thread (OpenFileThread()) and open a file. It starts out by making the BIP file and then validating (Check for errors in it) it (BipReader.ValidateBipFile(), file BeepXtreme.cs, line 975) but it stops on there! It doesn't throw me an exception or anything, it just pauses at the if statement on BeepXtreme.cs line 979, and the ValidateBipFile() won't execute because I tried debugging with a pause at line 298 in BipReader.cs. What's causing this?! Thanks very much! Smile | :)

Basically you get stuck in an infinite loop because the method you are calling, are calling itself.

public BeepCollection FileParams
{
  get { return this.FileParams; }
}

Actually, this is same as BeepCollection FileParams_get(){ return FileParams_get() }. Do you see now how it is calling itself? Maybe you know recursion but you was confused by syntax of properties. Properties are syntactic thing only, in reality it generates setter (and getter) functions. Is it clearer now? Smile | :)

Set Breakpoint at

public BeepCollection FileParams
{
get
{
/* Set Breakpoin Here*/	return this.FileParams;
				
}

You will see that you will never goes out of the body
Of FileParams Property because the Body Call The
Property again and so on
This Like you wrote somthing like

public int Sum(int i,int x)
{
return Sum(i,x);
}

this will still sum i and x and

Return the member variable that actually backs up that property, instead of returning the property itself, which is what is causing infinite recursion.

class X
{
   string fileName;

   public string FileName
   {
       get { return fileName; // NOT FileName }
   }
}

You need to Declare class member like

private BeepCollection beepCollection;

and the Change the implementaion of FileParams Property
to

public BeepCollection FileParams
{
  get
  {
  
   //return this.FileParams;
   //instead write where beePCollection is member variable  
       return beepCollection;
  }
  set
  {
    this.Lines = this.FileParams.Count;
   //Replace the following line 
   //this.FileParams = value;   
   //with this
   
    this.beepCollection=value
   }
}

Please Help : Marshalling in C#?

Dear All,

I have the following issue...

I need to call a function from an unmanaged dll...

One of its input parameters is described as follows;
CvContourRetrievalMode as the datatype name
and it takes one of four values{CV_RETR_TREE...etc}

so shall I define it as enum or what?in msdn I found only examples for strings,structs and classes?any suggestions?

Thanks and Best Regards,
E.A.

An enum will work fine. The important bit is that your datatype is the same size as the expected datatype.
