  2. Re: Failed to open the explicitly specified database

    make sure to check under services the user used to run the DataFlex WebApp server service
  3. Re: Failed to open the explicitly specified database

    you need to look at your connection string. it will either contain a user and password or the word Trusted_Connection. if Trusted then it will use the currently logged in user

  6. Re: Deadlocks - never get one when you want one

    just working on recreating things like that. A simple deadlock is not hard. just use two diff records

    user/program 1 creates a transaction and finds rec 1 and waits

    then user/program 2 creates...

    Re: Error 4106: Lock time-out

    we do have utility functions to monitor locks to prevent things like that

    i like to add a check after complex lengthy operations to ensure there are no accidental locks left

    if you exit the...

    Re: Error 4106: Lock time-out

    timeouts and deadlocks are of course part of a complex app.
    Problem is DF has no real way to deal with them nor any doc on how it handles them internally and from what i can see in my testing it...

    Re: Error 4106: Lock time-out

    Would love to share once it is ready.

    currently seeing some really odd response to a deadlock and the test programs seems to confirm it but more detail is needed to verify.

    i think this may...

    Re: Error 4106: Lock time-out

    just to add over the years we have been fighting a number of weird issues regarding lock timeouts and deadlocks with DF.

    Currently investigating another one that looks like there is something bad...
  13. Re: Get_Argument_Size and Chilkat change of behaviour ?

    this is one of the reasons why we write most of our interfaces in C#. too many issues with DF and a number of them are timebombs that you often may not realize during dev

    Re: AWS Traffic

    what traffic are you looking at.

    between database and RDP server it doesnt matter if you show it or not. if you dont use a constraint that can use the index or a sql filter or sql statement the...

    Re: cImageContainer - Make Faster refresh

    what you can do is to paint on an off screen bitmap and store that and then when you get a paint message only blit the effected area. You also have to change window class properties as DF by default...

    Re: cImageContainer - Make Faster refresh

    not going to help if the classes behind it do not support it. Most of DFs classes will always do a full repaint. and if you were to implement all your drawing and erasing code yourself you'd have to...

    DF doesnt really have the needed tools to do something like this

    DF also has almost no smart repainting for its controls. It generally for the most part always clears and repaints the full...
