Re: Library References - C# Discussion Boards

5-Oct-04 4:11

Hello all.

I made a NET class library, and now I want to reference it in my application.

The add references dialog allow me to add a reference to the library but I want to reference the library in is Debug version when I'm in the Debug version of the application and its Release version when I'm in release mode ( as I do when I write code in C++ )

Is this possible or I only can reference one dll for Debug and Relese ???

Thanks.

Do you want to know more?

If your two projects are in the same solution then you reference the project rather than the DLL (properly called an assembly in .NET) and Visual Studio takes care of the Debug/Release versions for you.

I think this doesn't works.

We have solution with an appication an a class library. Right now, the class libray is reference as a project, but my boss showed me on Friday that in a Release build the DLL that was copied to the Output Directory was the Debug version so I would prefer to use other solution (if exits)

That doesn't sound right to me. If you do a release build it should build the release versions of each of the assemblies. Did you do a rebuild of the solution? Make sure by deleting the bin and obj directories and seeing that it is building the right thing.

Yeah I know that this strange but my boss showed to me. He made a rebuild of the release version and in the ouput window it showed that the Debug version was copied. Also we look at the dates of the dll and
really the Debug version was copied to the Release output.

The only thing I can think of is that the properties for the project(s) are messed up somewhere.

I suggest you look at the properties for the project, in the Configuration Properties->Build page check that the Debug and Eelease versions are being put in the right places. For instance, check that the release isn't being put in the Debug folder or vice versa.

Is the source for the .DLL in a seperate SOLUTION? What Colin is telling you will work if your .DLL Project and your application project are in the same solution.

No, there are in the same solution. The only thing to comment is that the application is written in c++ and the dll in c#. I don't know if this can be the reason for the problem

Dave Kreskowiak6-Oct-04 13:11

Then there shouldn't be a problem. If you rebuild the entire solution, instead of a project, AND use project references instead of assembly references in your C++ app, then selecting Release or Debug should apply to all projects in the solution.

Hi~

I am writting C# application to call a VC++ dll by P/Invoke.

There is a CString argument type for the method in C++ dll exposed to C#.

What is the corresponding data type in C#?

Thanks

You can freely substitute CString objects for const char* and LPCTSTR function arguments. And here in C# you can go for string.

For the P/Invoke you should use StringBuilder

Hi all,

I want to write a c# application which can track the action on files in
window, e.g, when an user move a file from one place to another place in window, the C# application can record this event and the destination place.
Could anyone give me some hints how to start it ?

Thanks
Patrick

C# output files

Hello all.

I'm a beginner in C# and right now I'm developing a class library.

I have seen that when I build the project two directories are created bin and obj.

The first one is the output of the project, which I know I can modify the path in the project settins. This directory have two subdirectories Debug and Release and each one of those two stores the output file and and PDB file.

Also, In the obj directorie, I found the outfut file of the project and the PDB file. I don't know why this directory is created. I would like to avoid this to be created. Also I'm not sure where is placed really the ouput of the project, in the bin directorie, in the obj or in both.

Can anyone explain to me this behavior.
Thanks in advance.

It's created during the compile of your project and used for linking various parts of your project together in the final steps of creating your target executables. No, you can't stop it from being created.

In the bin folder, under either Debug or Release, depending on what configuration your compile is set for.

using Graphics on an indexed image

I've been working on a graphics editor application, and so far it's working nicely with 32bit bitmaps. The problem I'm getting now is that I'm stumped as to what to do with indexed images

The following code works happily with 32bit images:

Graphics G = Graphics.FromImage(xBmp);
  Pen xPen = new Pen(xCurrentColor);

  G.DrawLine(xPen, xStart, xEnd); 

  G.Dispose();

But fails on the first line with an indexed image (as apparently Graphics doesn't support indexed images)

Is there something alternate I can use, or am I going to have to implement something myself from scratch?

I've thought about making an internal copy of the bitmap that is 32bit, and then just converting it down to an indexed image when necessary, but I'd much rather work directly on the indexed image itself

According to MSDN you cannot use the FromImage method on a index image...

If the image has an indexed pixel format, this method throws an exception with the message, "A Graphics object cannot be created from an image that has an indexed pixel format."

What you can do is create a new image that is the same size as the index image, paint the index image into the nonindex image (u open the index image by using the Image.FromFile static method), make modifications, then save to indexed again.

Sending ANSI to Printer Driver

Hi,
I'm trying to set up a POS (receipt) printer (Epson TM-T88III Thermal). Epson has a windows driver for it. I don't know too much about programming POS printers (new to C# too). Using Windows fonts are slow with this printer. How would I send text (use ANSI??) to the printer driver so that the internal (default) printer font would be used?

thanks,
Ron
