• Visual Studio Express Editions Serial Port multithreading

  Is it possible for YourCOMPort.BytesToRead and YourCOMPort.DataReceived to change while the subroutine, which handles YourCOMPort.DataReceived is still in progress At very high data rates, the data may come in so fast that for example while previous data is being send to display by means of BeginInvoke new data are received. Depending on how Windows and .NET is build this may or may not course BytesToRead to change and/or a new DataReceived event, while the routine which handles this event is still in progress. If events are just boolean signals - not a queue - there may be a risk that if a new event occur while the subroutine, which handles this event is still in progress, the subroutine will not be reactivated (event cleared at exit). ...Show All

• SQL Server SSIS execution trees???

  Hi, With reference to the white paper http://www.microsoft.com/technet/prodtechnol/sql/2005/ssisperf.mspx#EBAAC about performing techniques in SSIS I would like to know how to interpret the details in Log Events.

• Software Development for Windows Vista Designer Serialization Problems

  Hello Everyone, I have the following dependency property shown below. This property should not be saved in the xoml file when I save the workflow definition. To not save the activity I change the DesignerSerializationVisibility attribute to look like this... [ DesignerSerializationVisibility ( DesignerSerializationVisibility .Hidden)] Unfortunately, setting the serialization visibility to hidden means that when I run my actual workflow the person object will be null. When I run a workflow I'm not actually executing the workflow definition that I'm designing (I'm hosting the designer outside studio). So, when the workflow is cloned in the runtime a new object is created and the PersonProperty is set to null - because the serializatio ...Show All

• Smart Device Development How do I provide Active Directory Authentication in .NET Compact Framework 2.0?

  I need to provide authentication from the .NET Compact Framework application to a Windows Active Directory. But I figure out that there is no System.DirectoryServices Namespeace in the compact framework. Does anyone has any suggestion on providing a Active directory authentication to a smart client Thanks Alex. The LDAP API supported by CE 4.2 and 5.0 allows me to login to AD. I ended up writing a COM wrapper for the API as you suggested. My project is for Pocket PC 2003 and the SDK provided by micrososft is missing the wldap32.lib. So I make my Mobile 5.0 (the file is there is the 5.0 sdk) working but is waiting for Microsoft to send me the file. See, http://forums.microsoft.com/msdn/ ...Show All

• Visual Studio Duplicate items are not supported by the "Resources" parameter error when building project

  Hello, While building our current project using Visual studio 2005 we stumbled on this error, === Error 16 The item "xxx" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter === we traced the issue down to resource file naming convention differences between Windows Vista and Windows XP ie, for a given form, if we include chinese traditional and chinese simplified resources, On Vista the resx files must be named with zh-HANS / zh-HANT , using zh-CHS/zh-CHT VS2005 will choke On XP the resx files must be named with zh-CHS/zh-CHT, using zh-HANS/zh-HANT VS2005 will choke This is really causing trouble, as we develop both in XP and ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 0x8878000a only in Win98

  Hi all, Im using windows 98. And Im trying to use a 3rth party aplication for voip that uses Portaudio and it does not record any audio. The play is working ok, but i can not record. When i debug the app, it returns an error calling the following function. result = IDirectSoundCapture_CreateCaptureBuffer( dsw->dsw_pDirectSoundCapture,&captureDesc, &dsw->dsw_InputBuffer, NULL); Its in the "dsound_wrapper.c" file. Its strange because in Windows xp it works fine ! ! ! Best regards, Windows98 only supports a single sound capture buffer, so it may be that more than one call to CreateCaptureBuffer is being made. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Texture Filtering Problem

  I have just recently converted my MDX project over to XNA, now I have slowly ironed out most of my problems but one that remains is the texture quality. My game looks the same as the old MDX one does when mip filtering is not enabled. Is there anything special in XNA that would stop the mip filtering from working or any kind of problem that would cause a similar look on the textures. It's like something is overriding the setting, but I cant figure out what it is. I have tried doing as Derek suggested: TextureCreationParameters parameters = new TextureCreationParameters(0, 0, 0, 1, SurfaceFormat.Unknown, ResourceUsage.AutoGenerateMipMap, ResourcePool.Managed, Color.White, FilterOptions.None, FilterOptions.N ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rotation help

  I think I'm being dense today, but I can't figure this out for the life of me. I have a model that I want to rotate across the X and Y axis. My issue is that when I rotate across the Y axis, I always want the rotation to occur as if the axis was vertical in terms of world space. If I multiply by my X rotation first, obviously the Y axis moves with it, so rotating about the Y axis will rotate it about its transformed axis. If I multiply by my Y rotation first, the X axis moves with it, so my X rotation is now turned along with it. I basically want to rotate downward and then left/right independently from what the actual transformed axes become...or, rotate left/right and then downward independently.  When I rotate about the X, it shoul ...Show All
