• Smart Device Development Scanning SDK in Compact Framework Issue

  Hi all, I have found an issue with the Imaging/Scanning SDK that the Compact Framework uses and would like to report this issue with Microsoft. How exactly do I go about do this Thanks Tryst The issue is that when I make use of the Symbol scanning (or imaging) API on the MC50 device in my application, and the device memory goes lower than around 7.50 MB (its got the memory slider indicating free program and storage memory on the MC50) I get a SCAN_ENABLE exception. When I get this, it means the scanner is screwed (disabled) until a soft-reset is performed on the device. I guess it doesn't free up all the resources when gets the first error. Symbol have told me that its the compact framework issue (what ever they use for the imager/s ...Show All

• Visual Basic Cannot launch .NET from VB6 using Interop Toolkit

  Hi, I am trying to investigate the Interop Forms Toolkit but I seem to have run in to a problem. I have followed the docs on how to create a .NET forms interop assembly and I created a very simple form as a test. The form was correctly marked with the InteropForm attribute. I generated the wrapper classes fine. Everything builds. I create a new VB6 exe, added a reference to the Interop Forms toolkit and my custom .NET forms assembly. I added the relevant declarations for the InteropToolbox too. Intellisense is working as I could see my library and form types when declaring them. The problem is that when I execute the code below: Dim f as New SimpleForms.InteropForm I get an error: Runtime error: 429 ActiveX compo ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Extra strip line

  Have noticed a little thing. I am drawing my background image in fullscreen mode placing it at 0,0, with backbuffer size. If at the same draw time graphics.GraphicsDevice.Clear (Color) method is using, clscolor stripline in one pixel width is seen at the top and utmost left lines. It is not sufficient in this case though, you can set Color.Black or not use this method at all. Strange thing is going on. Failed to represent this situation today - was curious to put on the presentation surface 3d object and see the result at extra lines. Unfortunately I have not saved the exactly state of my project and list of all programs running at this point yesterday. So I'll have an attempt once more today. But I have ch ...Show All

• Visual C# input data to website

  Ok right now I have to configure routers manually by inserting the exact same data into a router's configuration panel (website on router) then swap out the configured router with one that needs the exact same setup and redo this process over and over.

• Software Development for Windows Vista In July CTP, using StateMachineWorkflowInstance to obtain CurrentState freezes workflows in that State

  Dear all, I have a working StateMachineWorkflow hosted under asp.net 2.0. I have written a simple routine (shown below) to interrogate the current state of a workflowinstance: public string WfCurrentStateDescription(string WorkflowInstanceId) { // Get the workflowRuntime which was started in global.asax WorkflowRuntime wfRuntime = (WorkflowRuntime)Application[WorkflowRuntimeKey]; StateMachineWorkflowInstance wfInst = new StateMachineWorkflowInstance(wfRuntime, new Guid(WorkflowInstanceId)); return wfInst.CurrentState.Description; } I find that, once I have called this on a workflowinstance, that instance gets "stuck" in the current state and never transitions to the next state, even though code appears to get c ...Show All

• Visual Studio Assemply info task must be installed for all developers?

  Must the assembly info task be installed for all developers (As the < Import Project = " $(APPDATA)\Microsoft\MSBuild\AssemblyInfoTask\Microsoft.VersionNumber.Targets " /> is added to the project file) Also when I start the app from debug configuration from Visual Studio it modify the assembly info file. Can I only make this happen when I start from Team Build Or will this only happen the first time (I have not run team build yet). I was thinking about modifing my proj file as described in Guatam Geoenka's blog to get the assembly info task to work with team build.

• SharePoint Products and Technologies Worklow association to Content Type by CODE

  I am facing with a problem when I tried to associate a workflow to a Content Type through code. I want to create a Content Type that has a workflow associated to it. Later on when users can add this Content Type to their libraries, the document inside libraries can initate this workflow. I have done all the SPWorkflowAssociation bit and have done the ContentType.AddWorkflowAssociat ion(association) stuff. Everything seems to be working ok. I then added the Content Type to a newly created Document Library. And then I newed a document with that Content Type, the document item has a Workflows button (from the pull down menu)--this leads me to think that the Workflow has been successfully associated to the Content Type. But when I ...Show All

• Smart Device Development Multiline Textbox on WM5 workaround?

  I know that multi-line textboxes have problems on WM5 w/ .NETCF 1.0. Unfortunately WM5 Smarphones all ship with 1.0 and i can find a simple way to build a cab that would do the upgrade to 2.0 (if i'm wrong on this, please point me to a resource) and without a single click install, 2.0 just isn't an option. So i've created elaborate hacks to work around the paint issue, but every hack creates a new problem. Problem 1: When the multiline textbox draws it doesn't paint its entire background Hack 1: custom control which hides the textbox, paints its background then using a timer shows the textbox (now i can control that background paint and the textbox looks fine. Problem 2: Now the background paints, but T9 pop-ups on different phones will ...Show All
