• Smart Device Development Communication between Windows mobile and a server system with WiFi/GPRS

  Hi I'm investigating the different opportunities for communication between Windows mobile and a server system with WiFi/GPRS. The solution that I try to find is the one that is most suitable for communication over network where the connectivity is very poor, like GPRS communication. My system must be able to "puch" information from a server out to registered mobile devices... Do anyone know if Microsoft already have application/systems that handle the communication part (like ActiveSync, ISA-server) so I can concentrate on my own business functions Right now I'm investigate MSMQ, Sockets or WebServices. What is the best solution for mobile system that need to handle real "push" over wireless communication ...Show All

• Visual C++ ADO events handler

  How can I see record's content in raw_WillChangeRecord(...) Any method ( even Fields->Count ) returns DB_E_NOTREENTRANT. How it can be solved By the way: I did not succeed to get raw_WillChangeRecord in case of using SQL command INSERT ... . It works  with AddNew method  ( with data binding class I use ) only ! It looks strange, I tried to play with many params of Open() method but it does n't help. May be I did something wrong way, but no more than taking MS example and playing with it ( + of-couse a lot MSDN reading ). So: How does it work Crutial thing: Recordset pointer in raw_WillChangeRecord method does not allow to see neither record's fields, nor use Save( to XML&n ...Show All

• Visual Studio Tools for Office Hooking into form when adding new contact

  I am trying to figure out how to hook an event into the new contact form. The scenario is a user clicks create new contact. They enter the name in the name field and tab or click away. I want my event to be called so I can check the name against our CRM system. Is this possible I've figured out a way to get signaled in VBA (on the contact form itself), but all the code that communicates to my CRM is in .NET (through VSTO). Is this possible Tim, what you need is a wrapper class to maintain pointers to all open items whose PropertyChange events you want to handle.

• Architecture Architecture for Notification based application

  I need to develop a notification based system in .Net. Basically as and when certain data gets updated, the client machine is informed about it. There would be a windows based application running across all these clients. One way I was thinking of was to have the clients poll the server for any updates at frequent intervals. Whenever the Server does an update it would post the update into a queue. Every client would poll the queue for any updates. Would like to know if this approach is alrite or suggest an alternative architecture. Thanks Sai MSMQ supports IP mulitcasting - meaning you can broadcast the same message to all clients. Because it's using IP multicasting it won't work accross subnets (unless ...Show All

  Is it possible to write use HLSL shaders in WPF I suppose you are speaking about DirectX 10. I think that Managed DirectX doesn't exist anymore so there is no Managed DirectX for DirectX 10. When speaking about managed 3D frameworks which can be used from applications I guess there is only two options: XNA and WPF. ...Show All

• Visual C++ Bug in Windows 2003 winsocks or MFC CAsyncSockets implementation?

  Download this http webserver example from msdn. http://msdn.microsoft.com/library/default.asp url=/library/en-us/vcsample/html/_sample_mfc_httpsvr.asp Compile and run the software on any Windows 2000 box, with Visual C++ 6.0 or Visual Studio 2003. (I have not installed 2005 to try it with it.) Now inside c:\Webpages (the root dir) put a really large file, say 300k. Download it from another machine. If you had installed the server on Windows 2000 - the download goes very fast. I get (150kb/s). I use wget to time the download speed, and download from a unix box at a different location. You can also use Internet explorer to time the results, but wget is more accurate. Now copy the same server program into a windows 2003 machine an ...Show All

• Software Development for Windows Vista Application fails to start under Vista: "A referral was returned from the server." Manifest problem?

  I'm working on migrating a driver management application (written in Visual C++) to Vista. It requires access to HKLM, so it needs to run with admin access permissions. For testing purposes, we've been modifying secpol.msc to run it in admin approved mode, but obviously, that's not the right thing to do. The right thing to do, from what I can tell, is to add a <trustInfo> tag to the application manifest (which is embedded in the .exe as a resource). I did that, but now the application fails to start under Vista at all, with the error message "A referral was returned from the server." It still works fine under XP. The manifest is pasted below. Does anything look obviously incorrect If not, is there anything that could interact badly w ...Show All

• Windows Live Developer Forums VE 3, MS Ajax beta 2 and IE7 weirdness

  I just updating a site to use MS Ajax beta 2, from beta 1. Everything was fine under beta 1, but code that used to work under beta 1, is throwing an error under beta 2. Oddly enough it all works great under IE6, but not 7. I have just spent some considerable time examining the data, and everything looks fine. The problem seems to be with drawing a poly line, i.e. simply commenting out the line which adds the polyline to the map stops the problem happening: map.AddPolyline(poly); The array of lat/long looks fine, there are no nulls or anything odd, and doing ' map.SetMapView' on the array of points is fine too. To make the problem even more maddening, the problem is intermittant, and only on IE7, so for the moment I'm giving up ...Show All

• Windows Forms Pinable Controls

  I'm wondering if there is a way that I can create a control that will be able to be pinned/unpinned, mimicking the same functionality as the pins on each window within VS 2005 IDE design view (toolbox, solution explorer, properties, etc). I know this is possible with 3rd party tools, however, the constraint is that I cannot use any 3rd party tools. I need to use readily available tools within VS 2005 Professional Edition. I've been researching this for the past two days, and it looks like this is possible with a toolstripcontainer, but I have no clue how to go about doing this. I couldn't find anything that helped me much, just old versions using 2003. I do not need the control to be dockable during runtime. The only functionality that I ...Show All
