I am using SetScrollInfo to set the position of a scroll bar in a text box...
Basically the call is working as it sets the position of the scroll bar... but the text does not scroll and is still at the last position that the scroll bar was in - when clicking on the scroll bar the text scrolls to the correct location
I'm using Windows 7 and I built a small application that just moves the scrollbar of the current active window to some value.The problem is that nothing happens. I tried using GetScrollInfo too but I only got 0 in the nPos parameter.
This is my declartions and constants:
Private Declare Function GetForegroundWindow Lib "user32" Alias "GetForegroundWindow" () As IntPtr
Private Declare Auto Function SetScrollInfo Lib "user32" (ByVal hWnd As IntPtr, ByVal fnBar As ScrollBarDirection, ByRef lpsi As SCROLLINFO, ByVal bRepaint As Boolean) As Integer
[code]....
On the form load I just do a delay of 2000 milliseconds so I could focus on another window, wait and nothing happens.
System.Threading.Thread.Sleep(2000)
My.Application.DoEvents()
ScrollCurrentWindow()
I'm working on a new application and I use the SetScrollInfo and GetScrollInfo Api's and I'm having some problems: 1. I'm able to scroll my own textbox control on my form but I can only see the scrollbar being updated and not the text inside the textbox control moving I'm using this

I have a form1 that calls a form4. In form4 I have a cancel button, and a textbox. I have causevalidation set to false for this button when the Form4_FormClosing loads up, however when I hit the button to cancel it still asks me to validate the textbox. I'm not sure why causevalidation is not working in the child form.

I have setup a page in Excel with several textboxes for data entry. I would like to be able to tab from textbox to textbox so I can enter this data as quickly as possible.
View 3 RepliesIt appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

[code]When i put text in the textbox, move focus away, and then back again, i would expect the text to be selected, however it is not working for me.

I'm trying to make a application where the user can add a treenode to a treeview, and then after that they can add items to a listbox, making those items bound to that treenode?

I've been working on a program that takes input from a textbox, removes the punctuation, puts the words into an array (using the split method), and compares the array against a reversed copy of itself to determine if it is a word palindrome or not. I understand the logic, but I'm getting kind of caught up as far as what code to us. This is what I have so far, but no matter what I enter into the text box, nothing happens. I'm completely lost as to what I'm doing wrong.

View 1 Repliesin my form, i have a textbox in which its visible property is set to false. this textbox is bound to my table's primary key column.
whenever i try to add a new record, it automatically generates a value and i can see that when the visible property is set to true. now when i set it to false and do a messagebox.show(textbox.text), it shows no value. so i set the visible to true and then the messagebox does show a value.
i don't want this textbox shown in my form but i need to get the value from the textbox when the primary key value is generated.
how can i do this without showing the textbox?
I have been working on an app that was basically a vb6 app but had to be changed and I did it all using VB 2008. works well, great. One of the problems that I had was to work on different groupboxes or frames. Since they are layered on top of each other, working on one frame would mess up the others. Eventually it all went okay. but now if i want to add another item in the menu and hence add another groupbox (or frame) in the same app - it would definitely be a nightmare.

However I am trying to get my program into one little file. And I read how to Build Project and go to inRelease and get it from there. However it says this once I actually move it from its other files
Quote:
"*Program Name* has encountered a problem and needs to close. We are sorry for the inconvenience."
I get that as soon as I load it up. If there is any way at all to get it one simple file rather then like 3,4 files it would be so great.
I have this code to blur an image (a rewritten one from my Vista Forms project):
[Code]...
And it works fine for blurring a picture, but when I pass it a rectangle (and I know the rectangle is correct), it ends up stretched and very thin. I've attached a screen-shot of it "working". The red rectangle is the rectangle I pass, and the warped sort-of red area is where it seems to be blurring.
