Im trying to get an image from clipboard and save it to a file (.bmp)
Here is my
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Private Const VK_SNAPSHOT = &H2C
[Code].....
Btw (For the first code)If I press the Button the first time and i paste it manually(ctrl+v) to the paint the printscreen image is appeared.Also If i debug the code it works perfectly and it produces the .bmp file.
So im thinking its a timing issue , so I put a sleep(3000) after the keybd_event(VK_SNAPSHOT, 0, 0, 0) command and it still doesnt work.
I have a picture box and if I use Clipboard.SetImage(PictureBox.image) Then I can only paste the image into things like Paint and MS word. I can't paste it as a file into a folder/desktop.So how can I copy the image to to the clipboard and if gets pasted to a folder then it becomes a file?
View 2 Repliesi'm trying to save a picturebox but it gives me an error,
pictureBox.Image.Save(sDialog.FileName, System.Drawing.Imaging.ImageFormat.Jpeg)in runtime it gives me this error
"ExternalException is not handled "Generic error in GDI+ "
what's wrong?? to add changes on picturebox i do this pictureBox.CreateGraphics
i tried to save image into my database, it saves without error but when i tried to check if it saves in mysql, the data about my picture id save, but the image i save return a value of 0.

I'm getting GDI+ error when saving picturebox image to the database. My database is sql server with image datatype. Ideally when I browse image file to the picturebox then save using following code

I am writing a little program to convert LaTeX snippets to images which can be pasted into whatever program one can paste images into. It's working alright but the next obvious step is to include the source LaTeX code as a piece of metadata in the image so that the results can be modified without having to retype everything.
I have succeeded in adding a title PropertyItem with the latex encoded as an ASCII byte array as its value (id=800, type=2, value=System.Text.Encoding.ASCII.GetBytes(codestring)). I verify that the PropertyItem is really there before trying to put the image on the clipboard.
Then I do Clipboard.SetImage(myImage). The result is all of the PropertyItems are removed (my title plus anything else that was there)! I check this by doing MsgBox(Clipboard.GetImage.PropertyItems.Count.ToString) which gives zero.
This way, the copiedImage has the same PropertyItems as the original. However, new problem:
Other programs don't recognize what's on the clipboard as an image anymore, which defeats the whole purpose. I.e., if I put an image on the clipboard this way, when I try pasting into some context that accepts pasted images, nothing happens.
I have a problem when trying to save a picture box image ( I am using vb2008 express edition)When i load my windows form I create a folder called images and the current date (eg images 24062011) using the following code.
Code:
Dim fold As String = "images" & " " & Format(Now(), "ddMMyyyy")
If My.Computer.FileSystem.DirectoryExists("C:usersmickdesktop" & fold) Then
MsgBox(" file exists")
[code].....
this works fine and creates the folder on my desktop. I then load an image into a picturebox and try to save it using the following code which is where the problem starts.
Code:
Dim filename As String = Format(Now(), "ddMMyyyy")
Dim imagename As String = "image"
Dim fileext As String = Drawing.Imaging.ImageFormat.Bmp.ToString
[code].....
so my problem is why does the 1st statement give me the error as surely as I have declared that fold = the folder name then that path should be correct, as the program is set to save the image automatically, not using the savefiledialogue I don't want to have to manually type in the folder name every time I use the program.

I get "a generic error occurred in GDI+" raised. Googling reveals a few hits for this problem but seemingly mostly related to using databases rather than the file system.
Has anyone come across this? I don't want to paste all my code here in case my nemesis is watching, however basically I'm getting a reference to the PictureBox's Image property and manipulating the pixels using GetPixel and SetPixel, and then setting the picturebox's image property = my modified bitmap.
I understand that the error is generally related to the bitmap not being ready to be saved - is there anything specific I need to do to "close" the bitmap so it can be saved?The strange thing is that I'm sure this was working earlier today and now seems to have arbitrarily stopped working.

View 2 RepliesI'm making a simple little program. It's going to save the image in the clipboard (from pressing Print Screen) to the folder that the .exe is in. My problem is trying to find out how to save the image file with a user-specified name, such as "Image", then adding numbers to it. So it would be like Image_00001, Image_00002, etc. I would like to make the name be specified using a textbox (pretty easy). I know how to get it to save as different image formats and all, and I know how to get it to save as a hardcoded name in a hardcoded location, but that it isn't what I'm aiming for. If you've ever used the screenshot function of Fraps or MSI Afterburner, then that's basically what I'm trying to make here.
I've already searched these forums and did some Googling, but couldn't find anything that I was looking for. Not even a sample program with something like this. I found something in the CodeBank, but it's all the stuff I've already gotten implemented.

how to Check if clipboard has an image??
View 2 RepliesThe object is to load an image into a picturebox, then save a new copy of the image in a different location, but with the height and width of the image box not the original file's height and width but I can't figure it out. I've got the loading and saving working no problem but getting it to adopt the new size is stumping me, it just keeps saving with the original file's size properties

I wrote a program that copied an image from the clipboard and stored it on a file. The machine I wrote it on ran Vista. When I copied the programs over to a computer running XP the program wouldn't recognize that there was an image on the clipboard. It will recognize that there is text on the clipboard but not images. When I transfer the programs over to a computer running Windows 7 it works just like it did on the Vista machine. So I figure the problem is somehow related to the XP operating system. But how? Lots of programs I use on the XP machine can copy images to and from the clipboard. So why can't the one I wrote in Visual Basic?

I tried to use BinaryReader using ReadUInt16 but I get EndOfStreamException Unhandled error. ReadByte method works fine with an 8bit tif file. I do not know how to read a 16bit image file using binaryReader. Shouldn't I use ReadUInt16 since values of pixels range from 1200 to 4500?

The file structure is fine for retrieving data from the file but when I go to write data to the elements and hit any of the fixed array elements, I get an exception error. this has got to be a sytax problem I am just not seeing.
It seems that I am not addressing the array member correctly yet the same logic pulls it properly from existing records on file.
