Problem with Dephi 2007 and MyDAC 5.00.1.7

garyholmes · Post by **garyholmes** » Tue 29 May 2007 05:30

I have Delphi 2007 Pro and have installed MyDAC 5.00.1.7. When I attempt to open the MyQuery Editor for a TMyQuery component the IDE seems to hang. ESC will free the lockup but the edit window never appears. This also occurs when I click the (...) by the SQL property in the object inspector.

I have a colleague who experiences the same symptom with Delphi 6.

Any help is much appreciated.

I could not reproduce this problem. Please provide some more information about it:
1. Do you have MySQL Developer Tools, or the SynEdit components installed?
2. Does this problem happen for any TMyQuery component, or only for certain ones?
3. Does this problem happen with the empty SQL value of the component?
4. Can you reproduce this problem creating an application from scratch? If yes, please provide steps you performed.

1. I have tried it with and without the MySQL Developer Tools. I am not sure what "SynEdit" is.
2. It happens with all TMyQuery components in either existing projects or brand new ones.
3. Yes it happens with empty SQL values.
4. Yes I can reproduce.

a. Create new VCL application
b. Add TMyConnection component
c. Add TMyQuery component
d. Right click the TMyQuery component and select MyQuery Editor...
e. IDE locks up

I have completely uninstalled and reinstalled MyDAC as well as Delphi 2007. On reinstall the same problem persists.

Everything worked fine for the first month or so after initial install.

Thanks,
Gary

SynEdit is a third-party component set for syntax highlighting. Some SynEdit classes are used by MyDAC design-time editors, if it is possible.
Please check in any place of your program, what values returns the GetClass function with 'TSynMemo' and 'TSynSQLSyn' parameters. This may look like:

Code: Select all

if GetClass('TSynMemo')  nil then
  ShowMessage('GetClass('TSynMemo') is not nil');

if GetClass('TSynSQLSyn')  nil then
  ShowMessage('GetClass('TSynSQLSyn') is not nil');

I'm having the same problem.
I have MyDAC mydac71d11pro to D2007.

I have completely uninstalled and reinstalled MyDAC as well as Delphi 2007. On reinstall the same problem persists.

Everything worked properly, but gave error after installing a trial version of MyDAC (mydac19). I removed all versions and installed again, but the error continues.

Please, try to download the latest MyDAC build (8.2.5) and check if this problem still exists.
And uninstall all DAC products before installing MyDAC 8.2.
