• Windows Forms Using Win32 API to get mouse click

  Hi, I'm developing a small "colour picker" app in VB.Net to get the colour at a particular pixel anywhere on the screen (ie: not in the form).   I understand I have to call the Win32 API to do this, perhaps trapping the WM_LBUTTONDOWN event but I'm really confused as to how I am meant to do this from a VB.Net program.   I  ...Show All

• Visual Basic Visual Basic and graphics - for the novice/beginner

  Hi there I have no training in programming, but would like to start writing my own little programmes. In my work (civil engineer), I am increasingly frustrated by the lack of simple, time saving programmes to make my life easier, and hence the urge to write my own programmes. Of course, the start will be no more than programmes for one-off formulas, but having said that, I would like to (in many year's time) be able to write more complicated programmes. And of course what I have in mind involves graphics, specifically being able to draw (for instance) pipelines (with coordinates) and then be able to generate a longitudinal section from th ...Show All

• Windows Forms Error when modifying clickonce manifest

  Hi! Help is needed. I'm trying to create a ClickOnce deployment with VS2005 b2. I have to add a few additional dll-files. I use MageUI to add the files and re-sign the manifest files. However, this failes all the time. This is what I do: 1. Use "Publish solution" from VS2005 (this initial deployment works as expected) 2. Open [program].exe.manifest and add one managed dll'file 3. Click Save 4. Select the same certificate that VS generates for signing 5. Open [program].application 6. Select the manifest from 2 7. Click Save 8. Select the same certificate that VS generates for signing What step am I missing in this process Please, any id ...Show All

• Visual Studio Team System Getting sharepoint back after Beta 3R migration

  OK, I've got Beta 3 Refresh up and running, but the sharepoint sites didn't take kindly to the database migration (apparently). When I try to open a project site, I get an error message: The virtual server that is referenced here is not in the config database. So, presumably something is amiss in the shareport configuration.  So far though, I'm having a hard time finding my way through the Sharepoint configuration site. So - Which virtual server is referenced here   Exactly which options in the WSS config screens would I use to find it/configure it In the WSS config screens, I see the following virtual servers: Default Web Site&nb ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Error ding when all is well

  Hi all, I've built an application on top of the EmptyProject sample in the SDK. The application exits cleanly, but for some reason it raises and error sound. If I close the app with the close button on the window, the sample framework gives me a messagebox indicating that "The device has a non-zero reference count, meaning that some objects were not released," yet when I exit using the the GUI I've developed (which simply calls a function that raises a PostQuitMessage) I only recieve the error noise. I suspect that the problem stems from the timing of the call application's cleanup function. I call it from the WinProc when a WM_DES ...Show All

• SQL Server SqlDeveloper/SqlExpress Conflict.

  Hi, Background: I'm on a Pentium 2.4 with 1024 mb Memory and 160 Gb harddrive, running XPPro with SP2. I started a project in VS2005Beta2 with Sql2005Beta. When the RTM versions came along I ungraded to VS2005Pro, and tried to upgrade the SqlDeveloper. This ran amuck, but I could still access my database, so after three attempts I gave up temporarily. When it looked as if I was actually going to finish my project, I decided to sort out my Sql. Still had the same problems, but found the Cleanup Utility, which did a great job of cleaning up the residual stuff in the registry. I downloaded SqlDeveloper, and ended up with file reference ...Show All

• Visual Studio Express Editions Ascii through com-port

  Hi, I'm (very) new to VB Express but have some experience with VB. (Learning edition) I'm working on a project in which I'm communicating with a Serial device (an electronic payment system with a key). In VB I'm using the manufacturer's dll files to communicate with the key reader but it is also possible to send ascii codes. Is this possible in VB Express For example : To read out how much money is still on the electronic key (in the RS232 reader) I need to send out the following code {1,2}63 this is in hexcode 7b 31 32 7d 36 33 (the 36 33 is the checksum of 31 and 32.

• Visual Studio Team System GUI Change requires checkout of licenses.licx

  We are using a couple of 3rd party components that have information stored in the licenses.licx file. We have noticed that anytime you edit a GUI that has one of these 3rd party components, the IDE requires us to check out the licenses.licx file. The problem is that there is one licenses.licx file per project.  If I want to edit GUI-A, I have to check GUI-A and the licenses.licx file out.  If another develper wants to work on GUI-B in the same project they are unable to do so, because the IDE requires them to check out the licenses.licx file -- which I have previously checked out for my changes. Is this a problem with VS2005/Team o ...Show All

• Software Development for Windows Vista Vista backward compatibility

  Hi, is MS Vista supposed to be backward compatible with the other MS win32 operating systems I mean, if I have an application running on MS Windows XP, can it run on Vista as well thanks. My ADS Tech PTV341 DVB-S works only with XP, not Vista nor W98SE, something to do with BDA. ADS Tech has been promising a fix the last year or so. Thus Vista is NOT "backward compatible" Couldn't MS provide a 'switch' in Vista to enable the appropriate functions Regards, Roger ...Show All
