View 2 RepliesI am trying to change the cursor type to a crosshair but am having no luck. The program I am writing initially starts up as taskbar notfiy icon. Once one of the menu items is clicked the mouse cursor should change from an arrow to crosshair. This should remain like this when the mouse button is pressed again, held and then released and then it should go back to being an arrow cursor once again.To start off, I wrote the following code:
Private Sub changeMouseCursor(ByVal sender As System.Object, ByVal e As EventArgs) Handles DisectMyScreenToolStripMenuItem.MouseLeave
Cursor = Cursors.Cross
End Sub

View 2 RepliesI have an image that is using an indexed pixel format. I can't load such an image into a graphics object using loadimage. Ultimately, all I am trying to do is to overlay one bitmap onto a different one, neither of which will be visible for some time, if ever. That looks like it can be done fairly easily by loading the BMP into a graphics object, then drawing the other image onto it. However, that would require transforming the incoming image from an indexed pixel format to a non-indexed format.

View 9 Replieshave created a text editor, but I want to upgrade it with some serious functionality and userbility.
I have done most of the things that I had planned, but I have also come up with an idea that I am not too sure on how to code.
I have created a dialog box which opens when you click the options menu item in the menu stip control, I have customised this dialog box so the user can change display modes and so on but now I want to be able to change the language of the entire application as in from the default English (american) to French, German and so on.
When the user changes the language selection I want the text in the menu bar, the title of the app and the text of whatever is in the text box of the app.
I have created check boxes for the language selections, and invoked the check box click handle events but not sure how to proceed with the rest of the code.

View 2 RepliesI have created several small applications that use my own DLL. The problem is, this DLL is constantly changing. My current solution to this problem is that I have a Setup project in the class library solution that creates and registers the DLL. In all my applications I then have to open the solution and re-reference the newly created/registered DLL. Then I have to re-compile their setup projects, uninstall the old applications, and then re-install the new application.
There has to be a better way and I'm just not sure because I'm fairly new to all this. I have looked into ClickOnce but I don't think that will solve my issue as I cannot publish a class library. I have looked into checking version numbers but I must be doing something wrong because it doesn't work either.I understand that once a DLL is created and being used in an application it should essentially not be touched. I do not have that option in this situation. It is constantly updated. Done.
Edit: The DLL is not constantly changing during runtime but it is constantly evolving to allow more functionality and detail within the other applications. Also, one big thing I guess I should have mentioned is the Public interface is constantly chaning - usually adding new methods.
