I did think so! And I think Neddy's replies are for the questions. Knowledge will change the destiny. Open 2. MemoryStream image 3. FromStream MS. The three versions above: IO. FileStream imagePath, IO. MemoryStream image This lines is not executable code.

What type is "image" in this case? MemoryStream 'creates a new MemoryStream. Wednesday, February 22, PM. You can load an image from a MemoryStream like you load it from a FileStream. There is no difference. The only thing that comes into my mind is that you should be using the "Using" statement carefull. Don't dispose the stream because the Image uses it. But that's true for the MemoryStream and for the FileStream.

MemoryStream 2. Png 'save an image into a MemoryStream 3. MemoryStream MS and the problem is that i want to read it again in 3. MemoryStream MS and the problem is that i want to read it again in 3 After step 2, the stream position is at the end. In order to read the image, you must set the position to the start before step 3: MS. Seek 0, SeekOrigin.

Begin That's what we already wrote several messages before. ToArray i try like this with seek and without not work i think what JohnWein say is the problem The image codec reads the image and ignores what he has added so he can't recover it from the stream the image is saved to.

FromStream FS It works. Load 'Setup example form SourcePictureBox. Fixed3D Controls. Width TargetPictureBox. MemoryStream SourcePictureBox. Png 'Read stream into new image instance ms. FromStream ms ms. Close 'Set second picturebox to image copy TargetPictureBox. ToArray FS. Close its work if u dont need to read it again what with loops? After saving the image to the memory stream, reset the stream position to 0 and then create a new image from the stream:" How do you add text onto the end of an image stream and keep it there while loading and saving the image?

See my Steganographer program at johnweinhold. It embeds text in the pixels of the image. What is the length of your FileStream and your MemoryStream? Png MS. Close to read it i need MemoryStream so again new MemoryStream this what i dont understand i need now byte to read and i have image so i have to convert it to byte sorry but can some1 just save my time and write the code how i read the inage i spend lots of time for this i give up. LOL I am now Does this demonstrate the basic idea of what you are trying to do?

Open tempFilePath, IO. OpenOrCreate originalImage. Save strangeImageStream, Imaging. Write extraDataBytes, 0, extraDataBytes. Length strangeImageStream. Close 'Show proof of modified file Process. Start "Notepad. GetString sourceData. Skip splitPointIndex. ToArray 'desiredMemoryStream. Look for the message containing "I've tried exactly your code and added one line" EDIT: Now you will probably again start discussing about searching for " " even though you did not even mention it in that message.

MemoryStream System. End While Not desiredMemoryStream. Length - desiredMemoryStream. Position - 1 As Byte desiredMemoryStream. Read dataBytes, 0, dataBytes. Length 'Reset the stream position desiredMemoryStream. GetString dataBytes 'desiredMemoryStream. Has also been said before. Thursday, February 23, AM. Armin, I get the idea no1me is not reading the replies, he simply is waiting for a piece of code which he can copy and past and try. Cor, I consider it a communication problem only.

Edited by no1me Sunday, February 26, AM. We have no idea what you want to do. What doesn't work about the code you posted in your last post?

Close While Not FS. Close ' with FileStream i dont need this just with MemoryStream 'here i use the Data to save it End While and i already try with and with out dispose. Resources At least in fact you don't need for that the memorystream, however here the sample code.

MemoryStream DirectCast My. TheImage, Image. Save msX, Imaging. Click PictureBox1. Image End Sub Success Cor. You'll have to save the image and the file separately in My. Resources or save the stream as a byte array. MemoryStream imageBytes FS. Close 'here i use the Data to save it End While End Using Catch ex As Exception End Try End Sub There is your exact routine modified to take a byte array instead of a file path and to build a memory stream out of the byte array instead of reading the file from disk.

Though I still don't understand why you need the memory stream instead of just using the byte array. I don't find the OP too difficult to understand. He wants to save his combined file as an image in My. Resources and reconstruct the image and the file from My. Not an easy task. John, The first part, is impossible, the resources are serialized in the assembly by the Visual Studio tools.

For the second part I gave code 40 minutes ago. Wouldn't this be the way to execute his logic against an item in the resources? GetStream resourceName FS. Write byteArray, 78, byteArray. Length - 78 In fact something then for Paul Success Cor. You say it doesnt work but you do not say how What result do you get? What result do you expect? I officially join the ranks of the totally confused by the OP. Resources" "wein i dont want to save it to resources" What's next? If thats the case then this would never work using the file from Resources Good one Andrew!
