Running multiple instances of Javaw.exe
I am running a 3rd party application that runs in javaw.exe, when I try to launch the second instance of the application. The application doesn’t respond.
If anyone can guide, is this javaw.exe behavior (not running the second instance) or it’s just the applications behavior?
This behavior becomes critical when 2 or more user try to use the application remotely (via RDS or Citrix). In remotely access the behavior is that only... -

Thanks a lot tlhintoq for your respose,
But I think I could not convey my problem properly.
let me try again.
for example a "frmEnroll" (is some enrollment form) has a button "btnOk". The button "btnOK" is not allowed to a user "ABC".

Handling DPI changes in windows form
Hi,
I am developing a windows based application in VB 2005, the main form of the application is of fixed border style (i.e. user cannot resize the form), but in certain cases I am resizing my form through code. Intially the form has a fixed height i.e. 350 for normal height and 400 for extended height. But in this case the problem could not be solved effectively as the user can have different DPI setting e.g. 120, 144, 192 etc. The... -

For further investigation I tried to observe the behavior of other such controls e.g. Treeview, listbox and textbox (Multiline). I have...
