• Smart Device Development Unable to send custom properties (of appointment item) between pocket outlook and outlook 11

    Scenario -  in my program i want to sync appointments between my pocket pc and laptop. Issue - AppointmentItem object model of Outlook 11 (reference -Microsoft.Office.Interop.Outlook.AppointmentItem)  has different object model than the one Windows Mobile 5.0 Pocket PC SDK (reference -Microsoft.WindowsMobile.PocketOutlook.Appointment) Some key properties such as creationtime, modificationtime, etc are missing. When we create the custom properties for the missing fields (using Properties collection of Appointment class) and do the activesync, the custom properties (ItemProperties or UserProperties collection) are not reflected/synced on the PC (outlook 11). Question - Can someone guide us ...Show All

• .NET Development Memory management with picture boxes and wmp

  I have an application that has a couple picture boxes and a couple windows media players on a form. The main function of the app is to display images and play large (20mb) wmv files. Fwiw, it is remoted and controlled by another application on a separate pc. I noticed my memory usage (shown in task manager) seems to grow over time as I display new images and play new videos -- from a base size in the 20mb at the outset to 100-200mb over time. The application intermittently crashes when loading a new image or wmv, and it seems to be when the memory usage is high, so I'm assuming that's the culprit. I've added the following before setting my pb.image to a new image file: If pb.Image IsNot Nothing Then pb.Image.Dispose ...Show All

• Windows Forms Install from CD without user interaction

  Hi all, I'm trying to update my existing .net 1.1 app with a clickonce. The problem is, the old app resides on a machine with no keyboard, mouse, or monitor in almost 100 locations. I can easily ship a CD to each location where my clickonce has been deployed. The problem comes when the user puts the CD in a UI shows an acceptance type thing for installing .NET 2.0 and then requires a reboot. Is there any way to programmatically install .net 2.0 without user involvement other than just sticking the CD in Ok, for those of you looking to do this, the best way that I've found to install the .net 2.0 AND the clickonce app is to create a batch file that installs the .net 2.0 first, then the setup.exe for ...Show All

• .NET Development How to marshal correctly the following COM method?

  Hey, I have the following exotic method in a COM interface (copied from IDL): HRESULT _stdcall GetDeviceFriendlyName( [in] LPWSTR pszPnPDeviceID, [in, out] unsigned short* pDeviceFriendlyName, [in, out] unsigned long* pcchDeviceFriendlyName); As you can see, the first parameter is straightforward, but the second and third use a typical C++/COM pattern. The method is first called with pDeviceFriendlyName == NULL to get the number of characters that need to be allocated in pcchDeviceFriendlyName. The caller can then allocate the required WCHAR* and pass it in (unsigned short* is really a WCHAR* in this case). tlbimp.exe crawls on this of course, so I decided to define this interface myself. My ques ...Show All

• Visual Studio 2008 (Pre-release) Cost of Binding?

  Can anyone comment on the expense for large number (thousands) of data binds Fundamentally, what does it cost me to do a bind I already understand the benefits :-) thanks, Kiel If you're referring to a listview or something similar there is hope. ListView can virtualize the elements so that only those elements that are actually visible get created (and bound). This allows your UI to scale and display thousands of elements without creating thousands of textblocks or what have you. ...Show All

• Software Development for Windows Vista CorrelationManager.ActivityId changes when in a method under Workflow

  I am having an issue with the CorrelationManager.ActivityId changing on me when I am running inside of Workflow. I understand that the CorrelationManager utilizes the CallContext to store its state, but I can't figure out why the ActivityId is a different guid when running under Workflow. In fact, the ActivityID is set to the WorkflowInstanceId. Within my workflow method I can do a CallContext.LogicalGetData("System.Diagnostics.Trace.CorrelationManagerSlot").Peek and get out the stack in the same position I expect but if I do a CallContext.GetData("E2ETrace.ActivityID").ToString or (Trace.CorrelationManager.ActivityID same thing) I get the WorkflowInstanceId. This is causing me much difficulty when trying to log a ...Show All

• Software Development for Windows Vista Is ASP.Net suitable for hosting long running workflows?

  Given an approval scenario where a user is assigned a task and given a number of days to complete it, how can I set a timeout on the workflow instance I personally think that a Windows service presents a better WF runtime hosting environment for long-running (i.e. idled, unloaded, and persisted) workflows because of the flexibility and control related to life-cycle issues for the runtime, runtime services, and workflow instances. However, I don't believe ASP.NET would prevent you from hosting these types of workflows but there are several considerations to make and all are related to the fact that the ASP.NET/IIS environment is generally designed to be good at stateless, short-lived, request/response types of interactions. A long-run ...Show All

• Windows Live Developer Forums Best way to store coordinates in a DB

  Hi Everyone, Just wanted to get some ideas on what people see as the best way of storing coordinates in a DB (SQL, MySQL etc) It seems to me that a typical application may have to store millions of coords, especially if they are storing complex\large polygon arrangements. Is it really just a case of storing all the coords and crossreferencing them via an ID to other tables What are other people doing with this kind of stuff. thanks, SoS I'm using a SQL 2000 DB, hope to upgrade to 2005 sometime in 2007 In my tables i store the latitude and longitude as float (8), i actually call the fields "lat" and "lon" everywhere as i am lazy, I mean efficient, don't call longitude ...Show All

• Visual Studio 2008 (Pre-release) It is impossible to compile LINQ project

  Hi there! I have installed LINQ CTP May 2006 and Visual Studio 2005.NET Team Suite. And when I try to compile a simple LINQ application the following errors have occurred - "; expected". It looks like syntax of C#3.0 is not recognized. I did all steps described in section "IDE Support (for Visual Studio 2005/C# 2005 Express)" of ReadMe for C#.htm but no luck. Does anybody have any ideas what is the reason and how to resolve this issue Thanks in advance! We might be able to help better if you post the offending code. The compiler messages sometimes are misleading as to the source of the problem. Since you are not getting an error using var or the query operators, I suspect t ...Show All

• Windows Forms How can I programmatically autosize columns in Datagrid?

  I am using VS2003. In a datagrid, when I display a dataset, it comes with few columns. When I double-clicking section separator (= autosize column) it automatically extends the column to show max width of the column. How can I programmatically double-click autosize event so that all columns are displayed autosized level.C#, C++ or VB examples or link or examples are appreciated. Thanks in advance, Do you have the option to additionally run a Max length query on the result set and determine the index of that row while in still in SQL then you can possibly return that as an output parameter which the DataGrid can then quickly zoom in to calculate the graphical length.
