• Windows Forms Grouping

  Has anyone had any luck creating a control that is derived from the DataGridView that implements grouping This control is a major letdown without it. I've been working on a sample that does this when databound to a datatable. It will be a few more weeks until I get something posted on my blog. I'll create a post on this forum when I post it. It only works with databound through a DataTable as it relies on the filtering functionality of the DataView/DataTable. I currently have it working with only one grouping, but I'm also working on multiple grouping. -mark DataGridView Program Manager Microsoft This post is provided "as-is" ...Show All

• Visual Basic Session state in VB.net

  Hello all! I know there is a session state in asp.net. Is there something in a vb.net application that does the same thing Thanks! Rudy Session is really a concept of asp.net and VB.Net is merely a language used to develop ASP.Net web applications. If you asking if there is session state for for windows applications then the answer is not by default as its really up to you how you want to persist your application data. If you asking about how to use VB.Net to implement / manipulate session state for a web application then I would suggest asking the question on ASP.NET development are best asked in the forums at the asp.net site - forums.asp.net ...Show All

• Audio and Video Development Is Media Foundation ready for software development now?

  Hi all I'm new to Media Foundation and spent several days looking for and studying its information. As you know, we can find very few documents currently. The main source is the MSDN online version and is still very immature. Since Vista has already claimed MF as its next-generation platform for high qualitiy multimedia presentation and the PMP/PE forced people who want to take advantage by OS-native protection to use Media Foundation instead of DShow (as you know, PMP only supports MF.), I think people who want to develop multimedia applications (well, maybe for Bluray or HD) should consider now to change from DShow to MF. But from the documents I read and from this forum I saw lots of unresolved issues (including the multiple ...Show All

• Smart Device Development How to manage phone calls without using TAPI on Windows Mobile 2003 SE Phone edition

  When I'm using TAPI to manage the phone functionality of my device MDA III (Windows Mobile 2003 SE Phone Edition) I have a problem with GPRS reconnection. When I remove the code, which uses TAPI the reconnection works, but I can't use my phone. One solution is to use the default device’s phone application, but in this case I must invoke it, when I want to make a phone call, show it on the screen and transfer the phone number. The other problem is the case with incoming calls. I don’t know whether is possible to catch these calls without TAPI. I read some articles about RIL, but I don’t know how to use it ! Best Regards Tihomir Ignatov You don't want to use RIL. It is not designed for applications to use it directly, so ...Show All

• Visual Studio Invalid argument for database

  Hi, I have a report that is connecting to two different databases and retrieving data from a stored procedure in each. My problem is that when I try and set the destination of the database at runtime, I get the following error: Invalid Argument provided. Failed to open a rowset. Error in File C:\DOCUME~1\JAMES\LOCALS~1\Temp\temp_{5E8F9D66-6EFF-47E9-96F7-65D32A761DCC}.rpt: Invalid argument for database I have other reports connecting to the two databases and I am setting their destination at runtime with no problems. The only difference in this report is the fact that it is using stored procedures rather than tables directly. Strangely enough, when I set the designtime location of the database to be the location that i am sett ...Show All
