How can I, in VB.NET, set a window's z-index comparatively to other windows?
My program runs in the background of other programs, and when a specific event happens, my custom class pops up. However, sometimes, this window is in the background of other apps. How can I make it such that my window always comes to the front? I realize that there are questions like mine, but I cannot find any in Visual Basic.
im using vb.net to open IE and go to a website... i can figure out how to size the window, but not change the windows location on the screen... how can i make the IE window position always 0,0

I added a combo box to my form and set the tab index in the properties window to be in sequence. The focus doesn't stop there upon tabbing through the form. What is wrong? I checked and rechecked my tab index.

I have an application (chat) that I am developing for our company (special requirements). We are mostly using WinXP computers. I want it to be topmost and docked to the right, the problem is, I don't want it to overlap other windows that people are working on.
Is there a way to change the default area that other programs can maximize to? Basically, I want it to look something like this: Is something like this possible? I'm using VB.net so all .net answers are accepted.
I find myself with the dilema of opening massive numbers of IE windows/tabs on subjects. This is really great content, but then I need to restart my computer. Rather than going into each and recording the URL/window name (which is listed in the window title bar, relating to the content of the web page), is there a way to capture that information within VB.NET (in a WinForm app)?
View 4 Replieshow to set either a focus window or active window or something, but still able to move around in other windows with out my SendKeys function sending keys to any other window. This is the code I have to set the active window to the window I need to sendkeys to:

Now anytime I have like notepad or even my Remedy window up, it sends the keys to that window. how to set it where it JUST sends to the targethWnd I have defined and still move around in my other windows?
I have a window which should stay on top of Power point slide shows. So it should be on top of all the windows. I did this easily using VB 6 using Lib "user32", but it seems to be difficut with VB.net.

Is it possible to change the spacing windows have? and if so how? By spacing I mean the space that the taskbar reserves for itself.
View 6 RepliesI have an application developed in VB.net with 3.5 framework. I have disabled close (X) button on the main form of the application while doing some processing. I have achieve disabling by "Overriding ReadOnly Property CreateParams()" of the form. This is working fine as both control button on form and close option on right click in the taskbar shows disabled. This fulfill my needs on the Windows XP OS but not on Windows 7 OS. As in Windows 7 right click on application icon in taskbar shows a different menu, which has a new "Close window" option.
The close in original menu still shows disabled (this old menu is hidden but can be shown by holding Shift key and right click on the application icon in taskbar). Now I need to disable this "Close window" option as well and only for my application.
Is there a method through which I can do this programmatically.
I need to have a small window to appear slowly from the bottom of windows.is it a windows manipulation or it can be done in VB.net too.
View 10 RepliesYou know how you can use REMOTE DESKTOP and see your local drives as a type of SYSTEM FOLDER with a comment of DISK FROM REMOTE DESKTOP CONNECTION. If your browse to a folder you might see the ADDRESS look like this
\tsclientCWindows
What is tsclient? Is that a driver that is "expressing" itself like a folder structure?How about when you plug a camera or other device in a usb port and it shows as a G: drive, for instance?I'm guessing the G: drive trick is just a "driver" starting up for the usb port that somehow makes itself seen as a mapped drive.Is the \tsclient thing done the same way? Is there some kind of tsclient.exe that runs to do whatever this does?How can I make my own "pseudo" folder structure?
In VB.NET, how can I get the default window border size in Windows, for all standard windows?

how to get a hold of a opened windows explorer window and resize it.
Im using ManagementClass in order to open explorer but I have not figured out how to resize and reposition it.
I would like to have one Window (without child-windows) that can have multiple content-sets.For example: I want to have a set of lables and textboxes to save information for an object (like a person). This person has several sub-items. I want to have a set of lables and textboxes for these sub-items in my mainform too. But I don't want the lables- and textboxes-set of these two objects to be both visible at the same time.
View 2 RepliesI have a point in my .NET (VB) application at which the user is prompted to select zero to many documents to be printed, which are spawned off in separate new windowsThe list of documents selected is passed in from the previous page, pipe-delimited, as part of the querystring, which is then split to create a list of documents. My code iterates through this list, builds the new window's URL dynamically and then spawns the new window. For some reason I'm getting a maximum of two new pop-up windows, regardless of whether the user chose three or more, and the list is being populated fully and properly

So in my window onLoad method I am pre-populating a grid with values retrieved from a database. Here is the method below for the window load:
Private Sub winMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
''#Load Grid
Dim dt As New DataTable
With dt
[code].....
What happens is, when I press F5 to debug, the program loads, and the grid is still empty, just as it is without a datasource. When I try to step through the code, it actually reaches down to the line that reads
Budgets = BudgetManager.Process.Budget.GetAllBudgets()
and then stepping over this line...the window loads and it doesn't go any further in the method. What the line of code above does is eventually make a execution call of some SQL to a SQLite database, and the code gets to the point at which it calls the execute method, but doesn't even make the query yet. All the objects up until that point in the code are set properly as well (found through debugging and checking locals.)Edit:Exception is this:
"Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.
