• Smart Device Development Problem debugging simple application

  I'm having no luck getting my application to run on a Windows Mobile 5.0 device, so I thought I would try to create a simple project and test it out to narrow the error. Using the "New project" wizard, I select "Visual C++ | Smart Device | Win32 Smart Device Project". I then remove the "Pocket PC 2003" SDK and add "Windows Mobile 5.0 Pocket PC SDK". Finally, I select "Windows application" as the application type. The test application runs on the emulator, but when I try to debug it on a Windows CE 5.0 device (Intermec CK60), I get "Unable to start '%CSIDL_PROGRAM_FILES%\TestWinCE5\ ...Show All

• Windows Forms How to capture double Click event on combobox

  The ComboBox does not have a double click event. It does have a MouseDoubleClick, but that does not seem to work. I am trying to allow a user to edit the contents of a combo box by double clicking to open an edit screen in dialog mode. I have tried handling the MouseDoubleClick event, but nothing happens.  I have tried setting StandardDoubleClick for the form to true, but still nothing happens. Please help me.

• Visual Basic best practices to support resolution changes?

  As a newcomer to VB, when I developed my application I didn't think ahead to what would happen when users had different screen resolutions. Obviously this was a major oversight and I'm wondering now what is considered the best way to handle the problem. I designed the application at a resolution of 1280x1024, utilizing most of the available horizontal space. I tried setting the AutoScaleMode for the form set to dpi, but this caused considerable distortion when changing to 800x600 resolution. If I don't allow the form to autoscale, then scroll bars appear when the resolution is decreased, a major nuisance for a user. So, what I'm looking for ...Show All

• Visual C++ Simple dialog based app not working

  I'm thinking about moving from Visual Studio 6 to VS 2005. I've installed VS 2005 Beta 2. I've created a simple dialog based app, added a edit control with a variable, and added OnBnClickedOk function. In the OnBnClickedOk function I added the following code: void CTestAppDlg::OnBnClickedOk() {    UpdateData( TRUE );    AfxMessageBox( m_strMessText );    //OnOK(); } When I run the app the message box is empty. Any ideas what I'm doing wrong Thanks for the help, Brian I have just tried it on July CTP and it added this text. I guess, I am not sure wh ...Show All

• SQL Server Move conversation

  when you move a conversation to a conversation group, that conversation_group has to have been created previously, ie, you cant specify a non-existing conversation_group, right I ask because I am trying to develop an application where I use optimally one conversation related to many given conversation_groups, so that when I receive, I lock only a small determined subset of messages. What I could have used was a way to send messages on a conversation, specifying a conversation_group_id. Any suggestions You're right, MOVE does not accept a non-existing conversation group.

• .NET Development How to using datatable to create a table in DBMS?

  How to using datatable to create a table in DBMS there is a difference between datatables and tables in DBMS. Datatables are in memory representation of data, they contain columns & rows, while Tables in DBMS are in the DB. The typical way to use datatables is loading data from the database (table) to the datatable and manipultating the data the way you like, then apply the changes back to the database (table). ...Show All

• SQL Server Subfolders

  I know you can create sub folders in report manager, and then move reports into them. Is this a good idea since report designer cannot deploy to sub folders, and then you are left with deleting and moving, which throws off your subscriptions. Am I missing something Thanks! Here is what I have found out, however I have not done an extensive study yet. If you deploy a report to the root, you can use one of several methods to move to a subfolder. (Report Manager, etc) HOWEVER-If you have a report with the same name in the subfolder, you MUST delete it, thus invalidating the report id, which subscriptions and report history ar ...Show All

• SQL Server Wait for Recieve Fails to recieve message when called from .Net sqlClient

  I have been building out an application and Service Broker has been working great but I have this one nagging problem. There are some scenarios that involve users waiting for a response so I call a stored procedure that sends a message on a service and then waits for a responses on the conversation handle on which it sent the request. When I call the stored procedure from a query window inside management studio it works perfectly. When I call it from a .NET application it times out waiting for the response.  If I set a long timeout I can see that the response   was returned and is sitting in the queue but the waitfor receive just ...Show All
