With more controls, you c

When developing a personnel file system, it is common to use PictureBox to manipulate photos of people, including choosing to save photos, save photos, delete photos, such as:Save photos to the database and delete from the database, users write a lot of practical code, very useful. However, when you save a photo displayed on PictureBox as a disk file, it is very easy to see "GDI + generic Errors". There are

C # simple code to save pictureBox photos as disk files without errors, When developing the Personnel Archive System, you generally need to use pictureBox to operate on the person's photos, including choosing to save the photos, saving other photos, and deleting the photos, such: Save the photo to the database and delete it from the database. The user wrote a lot of practical code, which is very useful. Ho

After a program is developed, you need to manage the personnel information, which contains photos. Generally, the information of this blob field is relatively difficult to handle. After it is sent to winform, picturebox is placed and bound with bindingsource, almost no code is required to modify or display the photo information. However, many detours have taken place in the implementation process. Picturebox
