Placing A Form Above Desktop, But Below All Other Windows?
Aug 26, 2009
I'm new at the forums but not to .net development. I'm trying to make an application, which stays above the Dektop level but ALWAYS below any opened window. This application cannot be minimized, it has to be visible as a desktop background (just for getting you the main idea). As I was reading, I found that the way to make the form not to minimize is by using the WndProc function, and intercepting the Minimize message. My question is.. which of all the available messages is the correct for this case?.
P.D.3 (And last one I hope): See, the main reason of this application, is to make some kind of an "Active Desktop" function, which is not supported by Windows XP 64-bit. As XP64 doens't come with Active Desktop to use Web Pages as Desktop backgrounds, my idea is to make an application which loads certain web page and put's it on the desktop background.
In my vb.net windows form application i want make a button that when a user cliked the button, the Desktop should be showed, (Show Desktop Button) .Consider a form name as form1 and it got a button like "Show desktop", when user clicked, all the application should be minimized and it should show desktop, is there any Code for VB.NET Windows Form application.
I wanted to give my user an option for "Start with Windows". When user check this option it will place a shortcut icon into Startup folder (not in registry). On Windows restart, it will load my app automatically.
I have a project with a number of forms. In Form2, I have a split container. In panel 1, I have a number of radio buttons. What I have not been able to do is use the radio buttons to select a form to be shown in the panel on the right.
I have been placing my database fields (details view) on a form but for some reason they are all appearing as text boxes with the exception of date fields. Why are none of them showing as drop down lists?
I have been trying for ages to put an ActiveX control on a windows form for a CCTV camera I am using. I have registered the control with windows, added it as a reference to my VS2008 project and now it appears in the toolbox.When I put the ActiveX control on the form I always get an error saying "Failed to create back buffer surface" The control is added to the form however I can not get it to work and I suspect it has something to do with this error.I have an example project from the developers of the camera that does not have this problem, i.e. I can add the ActiveX control with no problems, however the program is in C++ and I am using VB.Net.Is there anything else I need to do to stop this error from occurring?I am using a CCTV camera from Zavio (F521E). The ActiveX control is called AxVideoView.ocx.
I have searched the web and this site for an answer but have not been able to solve this problem.I am not able to place a flashing cursor in a specified cell of a data bound DataGridView on Form_Load.My test project consists of a single Visual Basic 2008 form with a database created in Microsoft SQL Express 2005 using the Add New Data Source in the Data Sources window.The database has one table consisting of 2 columns.Column 1 being the primary key with Identity Specification set to On.The second column is a VarChar50.The DataGridView was placed on the form by dragging it from the Data Sources window thereby creating the Binding Navigator and the Private_Sub Form_Load code.I have added the code that should put the cursor where I want it.[code]
I need help on how to launch the normal windows desktop. I have a TCP Client/Server application where the client should start before any other application starts. To do this, I replaced explorer.exe with my application file path in the registry. What I want to do is the client minimizes when it receives a command from the server, and start windows as normal.
I am trying to overcome a problem I am having with remote desktop.Basically I have 2 machines running in different locations. I use remote desktop to access one of them (the "Remote Machine") from the other.("My PC")The "Remote Machine" is performing automated tasks that require the screen to be active, not the user login screen.
When I do so the Remote Machine logs off and presents the normal windows login screen.When I am finished reviewing the remote machine I log off and then I need to log back into the "remote" machine. It has no monitior but I can log in by pressing the enter key which sends a keypress to log into the user account( there is only one). In fact I do this the other way around. I press the enter key on the "Remote Machine" and this logs the user back in - terminating the remote session on "MyPC".
The problem is I have to physically go to the Remote Machine to press this enter key.This is a hassle - One solution is to remotely re-boot the remote pc but the lead time involved is too great.I am unable to fix this problem by tweaking setting or registry hacks so I guess the solution must be to cause the remote user to log back in programatically.I am an experienced VB user but I have never worked outside the windows environment. Ideally I would like to programmtically send a keystroke "{enter}" to the login screen but this doesn't work.
I'm creating a program that requires an MDI Parent Container to keep its Children inside of the client area. If you didnt understand id like a MDI to have all the forms it creates to stay inside of the actual MDI.
I've said like the windows desktop becuase thats what the windows desktop is. It's basically a realy advanced MDI container.If you know any methods on how to do this as this may be used a lot by future programmers and it would be great to just link this to the same type of question.
The following VB 2010 code runs, but returns only a black bitmap. I suspect the problem lies with the call to GetCurrentObject but I haven't been able to find good documentation on the arguments for it.[code]
i would like to build an inventory manager application that would have two versions :1. Would run on the desktop 2. Would run on windows mobile 6 I would like to have both these versions store and read data from a database that can be stored centrally either on a webserver or somewhere on the LAN.
I would like to know can i use Access as my backend database or sql server ? will windows mobile app be able to access it and read and write to it Note : I would prefer to create only one database that will just store the details in the tables and do not need any other functionality. All functions such as save,edit,delete,search,filter etc with be done from the FRONT-END VB.NET interface ONLY If you suggestion involves the use of 2 databases such as one for desktop version and one for windows mobile then please also tell me how would i sync the data between them.
How do you drag a listviewitem, to desktop, windows explorer, Ect...
For example, i got a listviewitem in a listview, and the text is the name of a file, and the Tag the filename, in a string... When i drag the item, to the desktop, or a folder in Windows Explorer, it will automaticly create a shortcut or something...

I'm looking to see if anyone has a good reference for a third-party add-in that will allow me to play .mp4 video files inside my program without a need to embed a web browser in my program.
I have no problem buying it (well that depends on the cost of course!), but I want that when I distribute it, I include their .dll files and it'll work on the user's computer without anything else needed.
I am creating a toolbar for the desktop. The only problem I have is that all though I have the windows above all others windows I need to have the other programs (not created by me) to snap or max to below my program etc. I have tried to search but have not found anything to help me or explain how to do it..
I am using Visual Studio 2010 Ultmate (visual basic 2010)..
I am using VB.net in VS2008.I wrote a screensaver that cycles through pictures. When the screensaver exits it sets the desktop background to the last picture loaded using API call SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, sFilePath, SPIF_UPDATEINIFILE Or SPIF_SENDWININICHANGE).The desktop wallpaper refreshes for WinXP and Vista but not Win7.In Win7, if I run the screensaver as an EXE then the desktop background changes when the program ends. If I run it as a screensaver I need click on the desktop and press F5 before the desktop shows the new desktop background (or click and drag with the mouse to show pieces of the new desktop background).I have tried to add delays and even force a refresh by using SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, Nothing, Nothing) but with no success.
Knowing the hWnd and the Title of all the desktop windows, I whould like to order them by start time order (them order on the task bar)In your opinion is there an API that gives those data? I can't use the Process.StartTime property because many of these windows have the Process.MainWindowTitle = "" and Process.MainWindowHandle = 0
Does anyone know how to capture (Record) the Windows desktop and save it as a '.avi' or '.mpg' file. This functionality can be done using screen capture / presentation programs like SnagIT:[URL]..I have found many examples showing how to capture from a webcam using the 'avicap32.dll' DLL file but these dont help with this problem.
If you are asking why i dont just use SnagIT its because the interface is overly complex and building my own version would allow me to intergrate it into my existing programs.
Where should I go to leanr to program stuff like getting keystrokes, locking keyvoards, changing desktop backgrounds, opening CD trays, changing IE homepage, etc.... Basically everything windows... I'm using VB.NET right now. Is there an api or something to learn for this kind of stuff?
