Create A Blank Image In A Picturebox?
Oct 18, 2010
I'm using this snippet to create a blank image in a picturebox, but is it possible to have the image coloured so that I can see it. (I'll need to colour it later anyway).
.Image = New Bitmap(newPictureBox.Width, newPictureBox.Height) 'blank image.
Also if it is possible, I intend to draw lines, rectangles on the image (hopefully) and save the lot, so would I lose the colour, or would it get saved, or does it depend on what it gets saved as?

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 am using VB.NET to try and capture a portion of the screen so I found this code in several places to capture the whole screen:
Dim screenSize = SystemInformation.PrimaryMonitorSize
Dim bitmap = New Bitmap(screenSize.Width, screenSize.Height)
Using g As Graphics = Graphics.FromImage(bitmap)
g.CopyFromScreen(New Point(0, 0), New Point(0, 0), screenSize)
End Using
bitmap.Save("c:scratchscreenshot.png", System.Drawing.Imaging.ImageFormat.Png)
This works with no error throw and the file is created successfully but the resulting image is completely transparent (it is the correct size) - This question relates to the same error but the solution is to use Win32 GDI which I want to avoid if possible

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 use vb.net. I am trying to do a file upload, I want the image to save to image folder, however, the image don't know appear in the directory that I indicate. If I click on "show all file", the image appear, but the image icon is blank or white like the image below show. So I click on that image and click on "include it in the project", however, it shouldn't be the case that I everytime upload an image, I need to redo that again. So how should I allow don't appear the white icon and to always appear in the upload folder when I upload a image instead of manually click on the image to include in?
This is my code
Protected Sub uploadImage()
Dim filename As String = FileUploadImg.FileName
Dim fileType As String = filename.Substring(filename.Length - 4).ToLower()
If (fileType = ".gif") Or (fileType = ".jpg") Or (fileType = ".png") Then
[Code] .....

I've got a working chart (ASP.NET/VB.NET), over some selected periods of time it has no data, this is expected. When I select a period of time where there is no data I get no chart displayed, just a rectangle of the background colour of the chart.
What I want is to still display the titles, x and y axes etc when there is no data, just an empty chart.
I toyed with the idea of adding a data point outside the time scale of the chart and this worked, I then got an empty graph, but there must be a cleaner way to achieve this.

I've got a chapter I'm supposed to be working through and cannot access the template for a blank solution. My instructions are as follows:From the "File" menu, select "New", select "Project", select "Other Project Types", select "Visual Studio Solutions", and select "Blank Solution."
I can see File, I then see "New Project", but not just "Project". I click on this and my only choices are :
Windows Form Application WPF Application Console Application Class Library WPF Browser Application
I've tried searching the installed templates for "Blank Solution", "Solution", "New Solution" and have no results. I've looked around for a couple hours hoping for a way around this and no luck so far.

I am running batch jobs on a job scheduler. One of the step is called 6 times so that we can execute the step parallely (to utilize the max server resource and to execuet the step in less than 2 hours rather 6hours). At the end of each instance it has to create a text file (6 instances = 6 text files) and the next job in the queue only runs when it could find all six files,
I am trying to create 6 dummy text files using vb.net.
1. to create a text file like file1.txt, when each instance of the step is completed running and it should exit the code after a file is create.
2. In this manner the code is executed 6 times and it must produce 6 files like file1.txt ....... file6.txt.
right know the maximum code i could write was ( and this is not correct)
Public
Function CopyFile1()
As
Integer
