• Smart Device Development power management

  Being frustrated by Windows Mobile 5 based device not going out of standby by pressing Voice Dial button on my bluetooth headset, I started looking for a solution. I failed to find any information about internals of power management in WM5. What exactly can bring it out of standby mode Why it powers up when I press the "redial last number" button on the headset, but remains in a sleep mode when I press "voice dial" Is there any way to catch events while it is sleeping, so I can power the device up and then run the voice command application Please provide me with some references in API where I can start from. Thanks in advance, Al ...Show All

• Windows Forms Forcing a virtual DataGridView to refresh its Cell values

  I have a virtual DataGridView that has a data cache behind it. Sometimes I update the values in the cache programatically and I want to be able to tell the DataGridView to refresh the cells. That is, for it to trigger the CellValueNeeded event. Currently I just make a call to DataGridView.Refresh() which invalidates the entire DataGridView and repaints it - which includes triggering the CellValueNeeded event. There are problems with this though. Firstly, it seems a somewhat brute force method. I don't really need to repaint the whole thing... Secondly, I have had intermittent Nullreference exceptions down in the GDI layer when I do a refresh ...Show All

• SQL Server Obscure error while attempting to install SQL Server 2005 SP1

  I successfully installed SQL Server 2005 SP1 on one PC. When I attempt to install it on a second PC, however, I get the following obscure error: Unexpected Error Occurred The following unexpected error occurred: That's right, there's nothing else listed, other an OK button. D'oh!

• Windows Forms Binding to RichTextBox

  Using VS 2005 Beta 2, VB, SQL Server 2000 I have an existing SQL table with a field 'Comments' of SQL datatype 'text'.  The data stored in the field was created using the RichTextBox under VB6. I use a Data Source/Data Set and set the Comments field to RichTextBox.  When I drag the control onto the form a RichTextBox is created but the control displays the existing RTF as text. I expected a RTF under DataBindings but did find it there. Is it possible to display/generate RTF in a RichTextBox and store the RTF in a bound field Here is a typical RTF string: {\rtf1\ansi\deff0\deftab720{\fonttbl{\f0\fswiss MS Sans Serif;}{\f1\froman\fc ...Show All

• Visual C++ Project Property Sheet User-defined macros evaluation order

  I am using project property sheet to store common settings for all of our projects. Include and library paths are among these settings. One problem I encountered is not all of our project files are at the directory level. This makes hard-coded relative path in the property sheets unacceptable since the relative paths will map to different directories in different projects. Once solution I have come up with is to use user-defined macros. The idea is to use a macro called "root_dir" which specifies the "root" directory of the source tree. I can then define the paths in property sheets use "root_dir". Since only individual projects know where ...Show All

• Software Development for Windows Vista Readonly WorkflowView

  Hello, I am hosting the workflow designer and when I execute the workflow I want to make the designer read only. Then, when the workflow starts I set the DragDrop property to false and when the workflow completes (WorkflowCompleted) I set the DargDrop to true. But when I set to true I get the following exception: ""DragDrop registration did not succeed." How can I make the designer read-only when I run the workflow Thanks, Pierre I have seen a similar problem happen when you don't specify the [STAThread] attribute for the application. Do it like this: [STAThread] static void main() { ... } Th ...Show All

• Visual Studio Express Editions Dumb newbie question regarding XP Styles

  Going through the video tutorials which show forms with XP style borders, etc.  However, mimicking those actions of the trainer, I only see plain vanilla-styled form headers and such.  I understand there's a way to "fix" this, but I don't know how.  Any referral links   Note that I have Visual Basic Express on an XP Tablet edition machine. BTW - Microsoft - why aren't XP styles the default for this new version of Visual Studio Tom Voila, resetting the display styles resolved it.  Someone was messing with this tablet and I didn't notice.  Thanks for your help. ...Show All

• .NET Development Pinvoke hangs when using .net remoting. Works otherwise.

  I'm attempting to use remoting to call into an umanaged DLL we have written to interface with an existing C++ program my company has written. However I have a problem I can't figure out.

• SQL Server Which method should I choose?!

  Greetings SSIS friends I want to implement the following query using SSIS Data flow Source component : SELECT * FROM someTable WHERE someColumn = 'H' How do I restrict the data coming from my data source By that I mean how do I apply the WHERE clause in SSIS ! Should I use a conditional Split component ! but that would mean retrieving all records first then adding the split component (not the most efficient method surely). Any suggestions would be much appreciated. Hi SSIS friend, Yes, you are probably right. If I am to convert all the joins in to merge join components then I would have to sort the input for each da ...Show All

• Software Development for Windows Vista Distributed/Shared Workflows

  Are there any samples floating about on the concept of building a distributed workflow I've seen some posts about using BizTalk instead, but it isn't necessarily the workflow I want to distribute. I want different applications to be able to contribute to the advancing of a shared workflow. So, take the classic trouble ticket workflow. Rather than having the same winforms app on the same machine push the ticket forward in the workflow, I want to experiment with having different workstations using the same winforms app contribute to the workflow, as well as an ASP.NET application also contribute to that workflow. I figured I could host a ...Show All
