i pulled some code off the internet for resizing images on the fly. it works great but only if i give an absolute address for the location of my files.
here is the portion of code:
Dim src As String = "c:downloadsff.jpg"
mage = System.Drawing.Image.FromFile(src)
[code].....
i am hoping that the possibility to locate all the controls that contain a certain image from the resources, and swap out that image for every control that contained it, will help me narrow down on the simple coding.
something similar to:
for every control that contains backgroundimage=my.resources.imagefound
replace backgroundimage=my.resources.imagereplaced
i tried the above code and it did not work.. lol..
I have written a simple program in VB 2008 that in a part of it, it loads some images from a directory with a formula like this :
PictureBox.Image = Image.FromFile(CurDir() & "photos�.jpg")
The photos are located in : inDebugphotos this works fine and loads images when I run the program.But after I publish, it can no more locate the files and I receive an Error:
Unhandled exception...
c:users.............................................photos�.jpg
Now I need your kind help please in these 2 cases:
1- Can you tell me how I can correct the formula?
2- After publish, dose the setup file contains my photos folder as well?
in my application, to get the path I use the following code.
Dim path As String
Dim asm As [Assembly] = [Assembly].GetExecutingAssembly()
path = System.IO.Path.GetDirectoryName(asm.GetName().CodeBase)
this gives path as Application Data, But i need Program Files to locate the .sdf file. how to get this path?

In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?

I need a code that will load text, the correct image to match it and the command for each image. what i want to do is make a program that will download a swf and an image into to folders. then at startup the program will load all the swf and images and put the images into a listview so when you click on the image for the swf file it will give the link to the swf so it can be loaded.

I hoping to find a current and simple way to do this. I'm using VWD Express 2008 and SQL Express 2008.I'm able to get the client's path to the image file using an asp:FileUpload control on the web form.
How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?

View 2 RepliesI have an image list and would like to add a directory of images to the image list in my code. How would I do this? When I run the code:
[Code]...
I get an out of memory exception. Currently there is only 14 images so there really shouldn't be a problem.
Wondering if it is possible. It works on the idea that all files share common code. The program would ideally analyse the source file and compare it to the reference files. It would then find common parts of the code and write it to a rebuild file. At the end the rebuild file and the reference files would then be able to rebuild the source file without it being present.
For Example.
source file code = xxyyzyzyxw
ref file 1 = xyxxzyzxwyy
ref file 2 = zxxwyzzywxx
The program would then analyse these files and make a rebuild file like the following
source(0,1) = ref1(2,3)
source(2,3) = ref1(10,11)
source(4,7) = ref2(5,6) + ref2(5,6)
source(8,9) = ref2(2,3)
Thus you would be able to build the source file using these instructions and the reference files.

I have already done the creation of button and the dragging of button at runtime already. But now i need to know how do i save the last dragged button on the form and also detect the name of the last clicked button.
i now drag a button to coordinates 25,254. so when i exit the form and the next time i launch it, the button will still be at 25,254. and this one will go on for the number of button i created like 100. so when i launch the form the 100 button will be at the exact position where i last saved them. the second part is lets say i created button1 and button2 on the form in runtime. so when i clicked the first button, it should display button1. and if i clicked on button 2, it should say button2. same goes for like 100buttons.

View 1 Repliesimportant info : my o.s. is windows7
i just recently published my app, and when i try to locate the exe file from the start menu/my app folder/my app shortcut's properties, i get this as a directory:
C:Users rujadeAppDataRoamingMicrosoftWindowsStart MenuProgramsmy application
now when i go to that location, in windows explorer, all there is a shortcut looking icon. when i check the properties for that, the Type of File : is Application Reference (.appref-ms) . is this my app, and if so, why does it have that little arrow on the icon like shortcut icons do?
i cannot seem to locate the .exe file by doing a system search, other than locating my other similar app which is located in a set folder and was not run from a setup. and if possible, how can i install my app in c:program files and not that set location?

View 4 RepliesI am making a program that stores all information that is entered into a directory and then zips that directory onto the C drive. It is working perfectly fine, but I think it would be easier for the user if the final directory was zipped onto the desktop.
Is there a way that VB.Net can locate the user's desktop and then zip the directory and place it on the desktop? For example, zipping it to "C:Documents and SettingsAdministratorDesktop" would work on my PC, but it may be different on a user's computer.
