• Smart Device Development Posible Bug in SerialPort Class???

  I’m migrating an application maded originally with VB embedded. The new application is in 2005 & CFW 2.0 SP1. The device is a Unitech 950 with dockh station (2 serial ports, 1 USB, IR). The original program worked perfect with the both ports. Now with .NET When I try to enumerate the serial ports, physical COM2 goes to "COM1", and the physical COM1 lost all the functionality. Anyway with the SerialPort.GetPortNames method I see all the physicals ports. What’s happening Can be a bug of "IO.Ports" Does anyone know how to solve the problem Sorry about my english I from Sevilla.

• Visual C++ linker .pdb file limit / dual core multiple simultaneous compilations

  We have a makefile based project. For enhanced functionality and portability nmake has been replaced with gnu make. To improve compilation performance I've set up make to spawn two compilation processes at a time for our dual core machines. On my mid sized test package this gives a "slight" performance increase. A full clean and recompile goes from 12 min 15 sec to 6 min 40 sec when spawning two compilations. Quite a lot better then I had expected. But simultaneous compilations causes problems with .pdb file generation when both processes try to write to the same file, so I've had to use the /Fd option to create individual .pdb file for each .obj file. This comes at a cost of, in this test case, 307 MB of extra .pdb files. Not go ...Show All

• .NET Development Object.ReferenceEquals Implementation

  Can anyone tell me where I can check for the Object.ReferenceEquals Implementation I'm tring to figure out the differences between Object.ReferenceEquals, Object.Equals and ==. I've gone to the link below http://msdn2.microsoft.com/en-us/library/system.object.referenceequals.aspx It tells me what Object.ReferenceEquals about, but it does not tell me how it's implemented. Thanks. While Reflector is an excellent tool to look at the framework code, it is not going to show you the true Object.Equals() implementation. It is written in C++. Your next resource is the Open Source implementation of the framework, the source code upon which Mono is built. It is unclear how closely the actual framework matches this source code; ...Show All

• Visual Basic Font Style

Or do I need to click on one of the fonts in the listbox and have it's style shown in another control. It's all OK, I figured it out for myself, I used 'IsStyleAvailable' in the first loop.

• Game Technologies: DirectX, XNA, XACT, etc. Question about Custom Content Processor

  Hi I have been working on a tile engine and have my Windows based tile map editor up and running. This editor produces an XML file holding all the tile set bitmaps, a list of all the levels in the map and a list of layers on each level. I have created a custom content processor which loads this XML file, parse it and serialise it to the xnb file. I have just completed my reader and it all works great. However, what I can't figure out is how to read in my tile set bitmaps such that I can serialise them with the rest of the map data. At the moment, it is up to me to manually add the tile set bitmaps to my game and then read them in during initialisation and pass the Texture2D's to the classes created by my custom reader. I hope this makes ...Show All

• Windows Forms Open Form, Close last form

  This is giving me a headache. I'm trying to be able to switch between two forms constantly. So I click a button, main form closes, next one opens. Then I click button on second form, second one closes and first one opens again. Each time they get open they must be new instances. So far for the second form's button I have Form1 form = new Form1(); form.Show(); this.Close(); Which works fine between the two except the second form isnt really closing. (Should be disposing). When I try this.Dispose(), the whole program exits before the main form opens again. Any ideas Something is really wrong. When you close your 1st form after showing the 2nd form, your application should terminate. Please show us the c ...Show All

• .NET Development Jagged arrays are not cls compliant

  Hi Guys, While analyzing my code with FxCop 1.32, I get the following "Breaking" - rule: "MyMethod" uses a multidimensional array of 'System.String[, ]'. Replace it with a jagged array if possible. ( Jagged arrays are not CLS Compliant .) " Please, help me with the above issue. Thanks in advance Yogendran (yogi) CLS compliance is that it follows the rule all .NET languages must follow.

• Smart Device Development TCP/IP transport via ActiveSync?

  I currently have my WM5 device hooked up to desktop PC via ActiveSync 4.1. The device is set up so that I can surf the internet using PIE. I have an HTTP server (implemented with HTTP listerner) running on the desktop PC, waiting for requests from a client app running on the device (using HttpWebRequest). Without WiFi switched on, the client app on the device cannot access the HTTP server.

Is it possible to access the desktop PC via ActiveSync instead of WiFi Thanks hmmm. You want to access the HTTP Server (IIS site) ...Show All

• Visual Studio Team System Team Foundation Install Problems

  Here is the situation I find myself today. Over the weekend some of my team members uninstalled the Team Foundation Server RC and installed the Team Foundation Server Workgroup (May 2006). I am trying to configure the foundation serve; but do not know if it was installed as local or active directory domain(they don't remember it asking this) . Is there a way to verify domain membership of the foundation server Team Foundation Server could not resolve the user or group '{0}'. The user or group might be a member of a different domain, or the server might not have access to that domain. Verify the domain membership of the server and any domain trusts. Also, since the Foundation Server was uninstalled will I have problems configur ...Show All
