• Visual Studio Report Source not Valid when using Remoting/Netrun

  Hiya! We are using Remoting for an application, and have integrated Crystal Reports. Currently we export the crystal report as a byte array from our business objects and write it to a file using a filestream. This works perfect in local and debug modes. When running thru remoting, however, we get a message "Invaid Report Source". The file IS being written... just cannot be read by the crystal report viewers load method. If anyone out there has a ...Show All

• Visual C++ Which tools for programming audio apps? Which book(s) to come up to speed with .NET?

  Hello, I've programmed in C but it's been a few years and I'm new to .NET (missed VC++6 and VS2003 entirely). I want to develop a Windows app, with gui interface.  To do this, I need to record sound from the microphone, manipulate the audio data numerically, and play it back through the sound card.  I don't necessarily want to store the data to a file, and in general don't want to do so.  The audio samples are not very long a ...Show All

• Visual C++ overriding virtual member function of a generic class using wizard

  in VS6 C++, "add member function wizard" was simple. but in VS2005 C++, it is no longer possible to copy and paste a function declaration into the "add member function wizard". (must add each parameters one by one....) for MFC classes, the property window provides a simple way to override a virtual member function, but that interface seems not working for generic classes. is there an easy way to override a virtual me ...Show All

• Visual Studio Help! Installation package is too large by crystal report 10 merge module.

  I created a new installation package by installshield 10, I added only CrystalReports10_NET_EmbeddedReporting.msm into installation package and don't add any other file, then build the program, the size of the installation packge is 120M, it is too large for us.

• Visual Basic Graphics question

  Hi there, I'm not sure where is the best place to post, but here goes anyway... I'm planning to make a graphics program in Visual Basic. Although I used Visual Basic a long time ago, and have somewhat of a knowledge of programming, I am by no means expert (you might say barely past beginner) and have been more of an enthusiast in the past (my real job is design and animation). Recently, I downloaded VB Express and decided to take the plun ...Show All

• Visual C++ VS2005 Linker /ENTRY

  We have a bunch of legacy DLL code which uses makefiles to build. The DLLs all use /ENTRY:SomeOtherName rather than the default and I've encountered a problem in VS2005. If I put the /ENTRY switch on the linker command line in the makefile, it doesn't seem to work - when I attempt to load the DLL via LoadLibraryEx(), I get an entry point not found error (0x7f). If, however, I put the /ENTRY switch in the LINK environment variable, the DLL loa ...Show All

• .NET Development loading classes from single project vs. multiple assemblies

  Hey guys, Are the below two cases identical 1. Having a single project with 100+ classes. 2. Separating the project into a bunch of assemblies and dynamically loading the assemblies. Second case involves the use of a lot of reflection and attribute-based programming. I am mostly worried about speed of execution. I am planning on going with approach 2, but am worried that there may be some unknown overhead to reflection or assembly based pro ...Show All

• .NET Development Embedding resources in a static assembly (Reflection.Emit?)

  I've been looking around a bit on the web now for information about how to embed resources into .Net assemblies, and everywhere, everything I find is about Reflection.Emit and about dynamic assemblies. I want to make an application which creates as it's output another application. This output application should always contain the same code, but different resources - so it's conceptually the same as a self-extracting zip archive. In this, ...Show All
