If I do the same thing in Paint it works OK. But if I open a .bmp file into Photoshop.Select All and Copy to put it on the clipboard. Then my code then reads the stream into a byte array and eventually makes a Bitmap from it.If I assign the bitmap to a background image it displays OK.But if I insert it into a RichTextBox using Khendys Gordon's method it does not display.However, I find if I clear the Clipboard before inserting it, it does display OK.I suspect the Bitmap is using the Clipboard for backing much like when and Image is created from a disk file.But it is confusing because I copy the stream into a byte array and make the Bitmap from the array. It would seem that once the values are copied into a new array the backing would not be in play any more.
There is Bitmap data on the clipboard from a screen capture. If I paste it into a RichTextBox it works OK. That is, if I remove the first two lines below.
Dim clipboardDataO As DataObject = CType(Clipboard.GetDataObject(), DataObject) Clipboard.SetDataObject(clipboardDataO) RichTextBoxTxt.Paste(DataFormats.GetFormat(DataFormats.Bitmap))
However, If I capture the clipboard data and restore it before I paste I no longer get my bitmap displayed in the box. My problem is, in the real situation I need to use the clipboard before I paste which is why I save it and restore it above.
1) Do you know why restoring doesn't appear to work here? 2) I can't paste before the save/restore. Is there something else I can do?
[code]When I run Module1, it creates the packet, fills in the fields, sends the bytes, and then crashes in P.Dispose when it reaches the FreeHGlobal statement.The error message is:The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))What do I have to do to free the pinned memory?
I'd like to ask if anyone knows how to properly use the clipboard to take information from a rich text box and send it to the clipboard. You see, if I try the following, which is pulling text from a rich text box, named RichTextBox2:
I'm working on a program that has to get a set of images and then scan them to find pixels that match colors in an color array. Anyway I think I got everything working but how to load the images in as bitmaps. See the images are dynamic, they change there filenames so I can't call them with a static call like Dim bmp2 As New Bitmap("c:button.gif").
So I am using a loop to feed the images into an array for bitmap but thats not working, anyway that I can do this as, right now the program gets all the filenames for the images from a text file that is sent in to us. All I need to do is have the program check each image for pixels that match our color list. But I cant get the images into the bitmap array.
In VB6 I drew a bitmap pixel by pixel (the pixel would a small square - not a pixel on the screen) using the line command, the coords, the colour and using the 'box fill' parameter [code]...
I am unable to read a pasted datagridviewrow object from the clipboard. All I want to do is, when a user has the entire row selected and copied, I would paste that row into the clipboard as a DataObject. That works just fine but when I attempt to read that DataObject (after the user clicks Paste) the DataGridViewRow that's saved in the clipboard always has a value of Nothing. Here's the code I'm using for Copy and Paste.
I have an application which take image from a folder through system, Io.filestream and convert it into bytes and store into database as byte data format and same I retrive from database as byte format and convert it into image into datagirdview. now I want to convert it into again bytes from datagridview. How to possible the value of image in datagridview into byte format.
My goal is to find the fastest way to convert a bitmap in a one-dimensional string array, where black pixels have to be converted in "X" characters and every other pixel in blank characters.My present attempt is to use a code like:
[code]...
But the Cpu usage is excessive, and the elaboration time too (I have to convert one Image by second).Can someone suggest a much more fast method, maybe using some Api??
I have a small 10px by 10px image, and I want to use VB.NET to find out if that image is (an exact) part of a larger image.I thought a method of doing this would be to lock the bits of the larger image into memory and then loop through each pixel in the image and for each pixel, I could take the 10px by 10px section which is down and to the right of that pixel.. and then compare it to my smaller image.
This is the code I have so far:
'Lockbits of larger image to memory Dim bmp As New Bitmap(Image.FromFile(System.AppDomain.CurrentDomain.BaseDirectory() & "picture.bmp")) Dim pxF As PixelFormat = PixelFormat.Format24bppRgb
[code]....
when I'm looping through the 10 by 10 section and I find the R G B bytes for each pixel, how do I store this in my rawImage array so I can convert it to a back bitmap and compare it with my original small 10by10 image?
I'm using Bitmap to show picture box like slideshow using Timer. For each timer interval, I've to go for new instance of Bitmap, there System memory increases to 1MB, How to resolve this, 'BG is picture box

how can i create a monochrome bitmap from a semi transparent bitmap in vb.net? the bmp is for a transparency mask image for an icon i'm trying to create with the CreateIconIndirect API function.
i'm using vb2008 .Net3.5, but i would prefer an answer that would also work in vb2005
I have a grass image located here in my directory. I want to just create a Bitmap, but I am getting an error. (Parameter is not valid.) Immediate Window: A first chance exception of type 'System.ArgumentException' occurred in System.Drawing.dll
With a network tools application I'm putting together. I have all the information shown in text boxes and have a piece of code to copy the text to the clipboard but its not working. It works on the other text boxes but not on this one the code is.

I am using VB 2008 (.Net 3.5) and MS Office 2003.Can someone please tell me how can I clear the Office clipboard from within Vb .Net. I read lot of posts on variuos communities and found that till version 2000, Office allowed it. Later MS closed the backdoor.My programming logic expects me to check if Office clipboard is empty before I perform cetain action.
although this topic has been posted for many times, I still can't figure out how to copy multi formats in clipboard.For example, I have a class called "Meta" and it contains data of a drawing. So if someone copy it to the clipboard, it should contains the original data of the class in a custom format called "drawing", a metafile of the drawing and a bitmap in case some app can't read metafiles. How exactly can I do?
I want to copy a datatable into a clipboard so I can paste it into excel and other programs I use, how can I get that to work? If there is no way to get it to work, how can I get a datatable in the clipboard and have it tab delimited?
Anyone know how to programmatically copy a set of controls to the clipboard, so the designer can then paste them onto the form?I want to make a function to select a set of fields from the database, make them into configured controls, then put them on the clipboard so I can paste them onto my form in the right area.
I have an explorer type window in this application I am building and I need to be able to copy files, folders, etc (in any combination) to the clipboard so that they can be pasted elsewhere. I cannot get the clipboard to copy the files in any format that will allow them to be put back out the same way.[code]...
This is kind of a two part question. I'm trying to make a very simple automated program that will run two stored procedures (one that updates, one that displays the new results) and then copies the results to the clipboard and pastes it in a new e-mail. I already have the e-mail generating and grabbing whatever is on the clipboard, but I need help with the store procedures.
Every guide I look at on Google seems to show a slightly different way of working with SQL, but I threw this together and need to know if it's working. I don't get any errors and the program "hangs" about as long as it takes for the actualy SP to run, but how do I get the "rows affect" output into a textbox or something?[code]...
