How To Change A Button's Image During A Long Process
May 29, 2009
I've got a common search button in my app that has the typical static magnifying image displayed on it. When the user clicks it I want the button's image to change to the animated search, to inform the user that the app is doing something (searching the database). Then when the search process is complete, change back to the static search image.
[code]...
When I comment out the line to change the button's image back to the static search image, (as stated above), and click the search button, the app actually performs the search, then when the search is completed, it changes the button's image.
Apparently VB or .Net is performing the under-the-hood process before the display/paint process, even though that's not the way it's coded. give me some insights on how to fix this, AND also please inform me of why this behavior occurs so I can try to avoid it in the future.

I'm wondering if it's possible to make sort of resource to change every button on a form to a resource image
so you make a form and every button on the form loads as a image from a resource you added
I want to make this globally and not by going on all the buttons and changing them one by one

I've been looking into creating custom controls, and I can't seem to find a good tutorial on how to do so. Everything I've looked at is extremely complex and I simply don't know where/how to start.
To start out with, all I want to do is change the image of the button (normal, hover, and clicked). No extra methods/events/properties/etc. I've made individual images for each situation with Photoshop.

I have a service ticket management application and users want to open several ticket details on a tab in a MDI frame. Since this application has to communicate through Web XML service with other company, it takes around 15 ~20 seconds. The users most complain is that he needs to wait until a saving process is done. Cursor is working while data is being saved and other can't be done

How can I automatically change the font size of the label when the length of text exceeds the maximum width of the label?
Also, how do I set when that should stop? I mean obviously it can't keep getting smaller forever, so what would you advise I do when the text gets to a really small size? Just stop text entry? How?

I develop in VB and often I'm writing long TSQL statements in SSMS but getting them into VB is a bit of a pain. I like SSMS during development because I can change the query / structure and test it when there are problems. Some of them become stored proceduresand some of them I just keep in the code.
I like keeping them in the code because when I have a problem with something, I can GREP my projects directory and find the code that does something (that I've forgotten) or someone asks something about how something works, I can look it up. I've yet to find a GREP for stored procedures. Is there such a thing?I've read in a "best practices" white paper how we're not supposed to concatenate super long strings with & _
[code]...
C# handles these things much better than VB. I'm wondering how I can keep my code together during development and searchable later. I had my hopes up when VS 2010 offered implicit line continuation, that this would help my multi line SQL procedures.Again, I was mistaken. Perhaps I could write it all on one line. I'd be interested in knowing if there's a feature that I am not aware of. Well there are certainly many features which I'm not aware of, but I was referring to "long strings".

I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?

How do you change the cursor image to an image from the project resources?
The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.

I have two combobox in a form: Cb1 and Cb2
When I load the form, Cb1 and Cb2 are connected to a bindingsource.
When I change Cb1, the code (below) changes Cb2 to show only the items according to Cb1
This is working fine.
The problem is when I change Cb1 , change Cb2 and click the save button..... Cb2 seems to be 'lost'...

In Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.
BlockInput(True) ' do not allow input during search and destroy
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor
Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:
FrmMain.BlockFrmMainInput()With these functions is the Main window:
[Code]...
It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.
