SQL Server Is my database connection alive and viable?
Currently, our application is issuing a 'select count(*) from systypes' command to check to see if the database connection is live (has not been reaped by the firewall.) This is somewhat inefficient. Perhaps a less expensive way to implement this functionality is to issue a ping statement to the instance At least a more simple SQL query is needed. I'm sure this function is typical in application architecture. What recommendations do you have for confirming that a database connection is alive and viable from the application Stephanie ...Show All
Smart Device Development GPRS Connect at Startup
Hi again (again), Last question, I promise. I'm looking to start the GPS up wen the device starts. I don't mind changing hte registry for this, or doing it programatically. All the stuff I have found is either for C#, or the registry info doesn't exist in my phone. Once again, any help would be very appreciated. Cheers, Dan. You need to set a few more fields in CONNMGR_CONNECTIONINFO .dwParams = CONNMGR_PARAM_GUIDDESTNET; Actually this will be enough, but make sure you call ZeroMemory on the structure before filling in the fields CONNMGR_CONNECTIONINFO pConnInfo; ZeroMemory(&pConnInfo, sizeof(CONNMGR_CONNECTIONINFO)); pConnInfo.cbSize = sizeof (CONNMGR_CONNECTIONINFO); pConn ...Show All

Windows Forms How to customize File open/save dialog box
Hi I want to add some controls like check box,text box,labels etc.., to the file open/save dialog box.So please help me how to start to achieve the task using c# language(preferable). Thanks in Advance Chandu.Sanka Hello, You may use some unmanaged code to hook up onto the dialog and modify the window (also there are components for that - see http://www.donationcoder.com/Reviews/Archive/DialogExtenders/index.html ).

Visual Studio Tools for Office Smart Tag dependency on .Net 1.1
We are targeting Office 2003 with Framework 2.0 only on the machines. This presents a scenario where the Smart Tags does not load even when the CASPOL is set for Framework 2.0. We have applied the solution as defined at http://support.microsoft.com/kb/908002 however this does not seem to have any effect. I was however able to make the same code built on Framework 2.0 work in Office 2007/Vista using the new PIA's for Office 2007. I have noticed a few posts indicating the solution is to have Frmaework 1.1 deployed, this presents another issue as each framework is about 26 MB and Change Management Solutions used to deploy these will have to pull it all over the network. Does anyone have an answer or any ideas, thi ...Show All

Game Technologies: DirectX, XNA, XACT, etc. How to: Make a Scrolling Background. null reference help!
I'm having trouble getting this tutorial to work. When I try to run it the debugger stops on this line: myBackground.Load(graphics.GraphicsDevice, background); and it says 'NullReferenceException was unhandled' and 'Object reference not set to an instance of an object.' What am I missing here Thanks George! That fixed it! Yeah sorry I didn't mention that all the objects were valid as far as I could tell. I had a feeling it had something to do with declaring myBackground with the new keyword but I was unsure of the proper syntax. What threw me was the error message wasn't very helpfull in pointing out which object was null. I've reported this error on Connect. Thanks again ...Show All
SQL Server Reusing package configuration file across all packages in a solution?
I have 5 packages in a solution. For 1st package, I add a package configuration file (xml) named common.dtsConfig containing only Database Connection configurations. For the same package, I add another package configuration file names first.dtsConfig containing configurations specific to 1st package. Now for 2nd package, when I reuse from existing package configuration (common.dtsConfg) with same name, it allows me to do that. I also create a package specific configuration file for 2nd package. And so on for all 5 packages. This works fine for development. If my database user/password changes, I edit onyl one file i.e. common.dtsConfig. But, when I want to create the deployment utility, it fails by throwing error that "cannot cop ...Show All

Visual Studio Express Editions Lots of things seem to not work!
I have had a number of problems with VB which nobody has been able to solve. Some examples are listed below: 1) File.Encrypt method does not work and generates an error suggesting that my file system is not NTFS. It's properties box states that it is NTFS. 2) I cannot run any program that I publish to work - get an error when I try to run it (even a test program that consistes of a single button which displays a message box when pressed) 3) When dragging a datatable onto a form, the designer sometimes autogenerates code that contains errors and will not compile. 4) I've had problems with bits of code from videos and books that don't work (yes, I've checked and double checked for typos) 5) Strangely, when I post a question to ...Show All
