Repetitive Image Loads To A PictureBox?
Aug 27, 2010
I am trying to do repetitive loads of images to one picture box. That is: An image is loaded to the picture box from a bitmap image.It is done this way so the image can be scrolled using the mouse.That works fine.The image is loaded from a file.When I attempt to load a second image from a file, I get an error indicating that the resource has not been released.I have tried Dispose() etc, nothing seems to be working.I started with VB 1.0 and worked up through VB6 over the years and am now transitioning to VS 2010. A bit of a neck snapper, but it seems to be worth it.

I am trying to write a program which loads a tiff image on picturebox. Then the user clicks somewhere on loaded image to set the starting x,y coordinates and clicks again to set the ending x,y point. Then clicks the run button and the starting and ending x,y points are written on label.
Just to test the program a loaded a tiff image that has a dimension of 75x75 pixels. When I click upperleft and downright corners of the image, the program outputs the coordinates as starting x,y as (103,89) and ending points as (170,157). The program outputs wrong coordinates becayse the image has 75 rows and 75 colums only. To me, it should have outputted starting point as (0,0) and ending points as (75,75).
Public Class Form1
Dim StartX, StartY, EndX, EndY As Int16
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I have an app that connects to a remote database.The connection to the database is triggered by the form load event of the main start up form which prompts the user for user name and a password.Here is my problem:Sometimes it takes a number of seconds for the database connection to be established after the user has double clicked the desktop icon. this means that during this period it appears that no action is taking place until the startup form becomes visible.Some impatient users assume that nothing is happening and double click the icon again.What I want to do is to have a graphic image or something pop up on the screen immediately when the program starts that displays something like 'Connecting To Database, please be patient"

I drew an image in a picturebox with the image height as picturebox height and image width as picturebox width. The image is placed somewhere on the center of the picturebox. My intention is to scale the image to fit to the picturebox.

I have a program I'm working on that, for one of the features, allows the user to drag an image from a picturebox, into the main form space, anywhere they want. [code]...
When trying to drag the image from the CurrentTilePicBox, the very moment I move the mouse while dragging the cursor becomes a circle with a cross and won't drag and drop into the new picturebox.

I have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.
This works fine when I give the location of the image (the full path ) on my computer - but then of course it will not work if I use the solution on a different computer .
So I have made a folder named "Pics" inside my application and added two images into it.
How do I get to this local folder in the following code?
Picturebox1.image = system.drawing.image.fromfile (??? )
instead of the usual,
Picturebox1.image = system.drawing.image.fromfile ("C:UsersMyName My PicturesMyPicture.jpg" )

I have to create a report that lists tests that a student has taken and how they answered each question...the column header layout (roughly) looks like:
Test #1 1 2 3 4 5 Test #2 1 2 3 4 5
TestA A B C D E TestB C C B C E
The problem is that the Gridview doesn't seem to like repetitive column names and is renaming the second set of Question #s to something else.

I am trying to find a solution, in eliminating repetitive string names, say for ex.,in a literal field, i am populating names of the contributor of certain article's history version, and so, if "ron" has contributed to the versioning of an article 3 times, the name "ron" gets added to this literal control, and outputs "ron" 3 times.

Repetitive Statements: Looking for an alternative to a function or subroutine. Years ago, I wrote programs for a company using a language called "Algol", I am sure some of you know of it and but many more do not, it is a pretty old language. It had a capability that I used called a "Define" where you could take a statement (for example x = y + z ) and create a 'define' which was a simple, short replication of that statement. (x=y+z) could be defined as 'mysum'. You could then use 'mysum' any where in the program in place of the 'x=y+z' statement.
[Code]...
Is there a similar type capability in Visual Basic? A sub routine does not satisfy the need unless the variables x, y and z are globally dimensioned to the module? I can do this, but would prefer not to. I am expect there is a similar capability, but I personally have only scratched the surface of the VB capabilities.

I have a listview with four columns (category, name, date , amount). More than one items falls in a category and I mark them with a number. ex - different kinds of pens as no.5. So, if I make an entry of five pens, five "5"s shows up in the category column. I want to display only one "5" in the category column and not to make it crowded with same numbers.

I have a lot of repetitive code that references components of my main form. I wanted to create a separate module (correct terminology?) for all this code to be contained. I cut the offending code and pasted it into my new module, changing each label reference, etc to form1.label.click
Form1 was then underlined and I get this message:Handles clause requires WithEvents variable defined in the containing type or one of its base types.I think I'm headed in the right direction, but what exactly am I looking for? Here is a sampling of the code that I would like to keep in a separate place other than Form1.vb:

I have a form with a picturebox that will allow to draw a free hand picture.
I added the initialization of the image in the form_load and the click event of the clear button. When I click the clear button the image is cleared and at the mouse move on the picturebox the last drawned image will shown.
My question is, how can I validate the picturebox whether it is empty or not?
