• Visual C++ C++ Newbie needs a c++ expert converting bits to bytes

  Hello all, I need some C++ experts to help me with a problem I have in converting a PBM file to a PGM file. These files are used to store digital images. The PBM file uses monochrome to display images while the PGM file is a grayscale image. I have written a test program that works somewhat. The problem I have is that the PBM format uses 1 bit to represent a pixel while the PGM format uses 1 byte to represent a pixel. Therefore 1 byte in PBM format represents 8 pixels. I need help in converting those bits to bytes for the PGM format. I am not sure how to achieve this. I have never really had any experience in masking bytes. Here is my code thus far: #include <iostream> #include <fstream> #include <string> using namespace ...Show All

• .NET Development thread-safe enumerator

    Does the use of yield as shown below create a thread-safe enumerator by any chance     IEnumerator<KeyValuePair<TKey,TValue>> IEnumerable<KeyValuePair<TKey,TValue>>.GetEnumerator() { lock (m_innerList.SyncRoot) { // Not thread-safe //return m_innerList.GetEnumerator(); // Is this thread-safe foreach (KeyValuePair kvp in m_innerList) { yield return kvp; } } } No enumerators are, by definition, not thread-safe. Making them thread-safe is actually a difficult task because just because you asked for an enumerator doesn't actually mean you use it. Most enumerators store the "version" of the collection when they are created. The first thing th ...Show All

• Visual Studio Analyze.exe (2005) crashes

  Hi! We are running an analyze (vss 2005) once a week on our database. Since one day analyze.exe crashes with the popup "Microsoft Visual C++ Runtime Library : Runtime Error! ". The last entry in the log-file is "Running advanced reference verification." The database format is v6. We use SourceSafe2005 clients and adminstrator. Our database is very large (5.5gb). Even MS suggests to keep this size smaller, this should not be a reason for the crashing of analyze.exe. Any ideas Thanks in advance. gofur.

• Software Development for Windows Vista CodeCompileUnit question

  Hi, I asked this question in the .NET Base Class Library Forum without any reply so far. Maybe someone can help here. I want to be able to create a CodeCompileUnit from source code to be in synch with the Workflow Designer. Using IEventBindingService I can genreate CodeMemberMethods but when I load the generated sources from disk I need a way to re-create the CCU to be in synch. VisualStudio seems to be able to do that. There is an internal class which seems to be able ... Any hint would be very much appreciated. Recreating code compile unit from C# code would mean parsing C# code. This is not possible. The other way to do it would be to compile the workflow when it is loaded, reflect upon the assem ...Show All

• .NET Development Problem creating Zip File using Shell32.dll

  Hi, I'm trying to create a zip file using the Shell32.dll com component in C#. I believe that the code should work fine in Windows XP & 2003 Server.

• Visual C# Practical use of multithreading???

  Hi all, I'm not an expert on threading and to be honest I've not used threads directly before.  I have an interesting problem I'm not sure how to tackle. Basically I'm developing a .NETCF2.0 application in C# and have a class that contains an event handler to recieve SMS messages using the PocketOutlook assemblies (API). When a new SMS message is recieved this handler parses it and stores the data within a SQL mobile DB.  Now most of this processing is pretty quick but I'm a little concerned about the overhead it will have on the UI thread.  My first though was to have another thread handle these events but I cannot find a way of doing this. Basically I want a seperate thread to use the SMS receieved event h ...Show All
