PRB: Checking Out Forms and MAK File Loses Changes in Memory

SYMPTOMS

A subset of the Visual Basic project files are checked out and modifications have been made to the files. If the rest of the project files are then checked out without first saving the changes made to the already checked out files, those changes will be lost.

CAUSE

Visual SourceSafe relies on Visual Basic to make sure all files are saved before reloading the make file (.VBP or .MAK). It appears that Visual Basic does not prompt the user to save changes before reloading the make file. Therefore, the changes are lost.

RESOLUTION

Be sure to save changes to your project files prior to checking out the MAK or VBP file. When the Select All Command is chosen during checkout, the MAK or VBP file is included in the list of files to be checked out. If the MAK or VBP file is selected to be checked out, Visual Basic will reload the MAK or VBP file.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Problem

  1. Start a project in Visual Basic 4.0. Form1 is created by default.
  2. Open a Visual Basic project that is under Source Code Control and has two or more forms in the project.
  3. Check out one form. Do not check out the other forms or the .VBP or .MAK file
  4. Make a change to the form, such as adding a button. Do not save the change.
  5. Select another form in the project window and choose to check out the form. In the "check out" dialog, choose SELECT ALL. Note that the list does not show the form you have already checked out, but does show everything else to check out. Press OK to check out the files.
  6. Note that the form you already had checked out closes. You are never prompted to SAVE changes.
  7. Reopen the form that was modified previously. Note that all the changes are lost.
