Solution 1

Based on numerous replies, I begin to suspect you are not being very clear about what you hope to accomplish. I'll do my best to guess. That said, it would be easier, if you simply provided more detail in the question.

To view a file with an image viewer, you need to actually have a file. The file should be on-disk, not in memory. Because you specified "C:\testImage.jpg" in your question, I naturally assumed that you had already previously saved your image to disk. Your later responses, seem to indicate this may not be the case.

So, your first step, if the image is not already on disk, is to save it to disk. You don't mention what type of application (WinForm, WPF, WebForm, etc.).

For the purposes of this guess, I'll explain for WinForm. The way to save an JPEG image, from a WinForm picture box, to disk would be as follows:

string myPictures = Environment.GetFolderPath(Environment.SpecialFolder.MyPictures);
string myPath = System.IO.Path.Combine(myPictures, "testImage.jpg");

pictureBox1.Image.Save(myPath, System.Drawing.Imaging.ImageFormat.Jpeg);

To display that image, using some image viewer...

// Use default image viewer
System.Diagnostics.Process.Start(myPath);

// Use image viewer application indicated by the variable "myImageViewer"
System.Diagnostics.Process.Start(myImageViewer, myPath);

I'm having a bad day today...fixed for real and tested this time.

Code no have errors, but in app when click on button :

The system cant find file specified!

Eric Lynch 4-Sep-18 12:24pm

That I cannot help you with. The error is very specific. You need to double check the file path. Either you have it wrong, or you don't have read access to the root directory.

Eric Lynch 4-Sep-18 12:26pm

Amending my previous reply, I can help. Your path is definitely wrong. Either get rid of the "@" or use a single "\". With both there, the path is wrong.

To clarify, if you use an "@", it means that "\" is interpreted literally, so "\\" is two backslashes. Without the "@", it means that the "\" is interpreted as an escape sequence, so "\\" is one backslash.

In Windows file paths, one backslash is all you need.

Process.Start("C:\windows\system32\rundll32.exe", "C:\WINDOWS\System32\shimgvw.dll,ImageView_Fullscreen " & PathOfFile);

This solution is ok, how to define PathOfFile?

I really have no idea what you are trying to accomplish here. Please click Improve Question, to add a lot more clarification to your original question. That question implied that you had already saved your image to a file named testImage.jpg and were expecting to use the default image viewer. I have no idea what this reply suggestions.

So, if you want help, please Improve your original question to include the following information:

1) Do you want to use the default image viewer to view your image? If not, list the name of the application you expect to use.

2) Have you saved the image to the file testImage.jpg (as your question implies)?

3) If you have not saved the image to file yet (and this will be necessary), do you hope to save the image from the picturebox?

Goran Bibic 4-Sep-18 12:49pm

1) Its default windows photo picture and its ok
2) No (Image is saved in db)
3) Yes

Goran Bibic 4-Sep-18 12:25pm

I have picture in picturebox. Retrieved from database

Just need to show picture from picture box to Windows photo viuwer

Eric Lynch 4-Sep-18 12:33pm

I replied to your file path issue, you were mistakenly specifying two backslashes (see earlier reply).

In this update, are you saying that you have not successfully saved the image to disk...to the file C:\testImage.jpg you mention in your original code?

If not, why would you expect the file testImage.jpg to exist? If this is the case, you really need to clarify your question (a lot).

Goran Bibic 4-Sep-18 12:36pm

Ok. Look. I have picture upload in picture box and save in database. OK?

Now when I click on row in datagrid I see picture in picture box.
Everything working fine.

Now I need that picture (from database) in picture box whit button to open in windows picture and fax viuwer ok?

Goran Bibic 4-Sep-18 12:38pm

Something like PathofFile= picturebox.value

Eric Lynch 4-Sep-18 13:07pm

Updated the solution with my best guess of what you want...more details would have helped.

Goran Bibic 4-Sep-18 13:12pm

Thank you men...alot

Eric Lynch 4-Sep-18 13:20pm

Goran Bibic 4-Sep-18 13:24pm
