Hi,
Is someone knows, where are the setting for sound audio acceleration
saved?(registry, ini file, value of the slider to be precise )
Or is there the way to change it programmatically (lowering or incrementing)

Regards,

C++ / VB Hi every one, I have a dialog application with a start button, a slider control, an edit box where the value of the slider control will be displayed and another edit box where the result of some operations made from a workerthread will be displayed. When moving the slider, the new value of the slider should appear in the corresponding edit box and the workerthread should be aware that the value of the slider has changed and should update the value of the slider in the calculations being performed. I created a class CWorkerThreadMgr (for the thread code) which the CStartCalculationDlg.h CWorkerThreadMgr m_WorkerThreadMgr / / instance of the WorkerThreadMgr CSliderCtrl m_Slider / / member variable of the slider control CString m_SliderValue / / member variable of the edit box, where the current value of the slider control will be / / displayed CString m_Calculation / / member variable of the edit box where the calculated

a duplicate copy of all the com ptogid's under the HKCU hive - ugh! My registry takes up twice as much memory, and I am reluctant to attempt to undo the Servers http: / / msdn.microsoft.com / en-us / library / ms693350(VS.85).aspx See also: INFO: Registry Entries Made by an ActiveX Component http: / / support.microsoft.com / default.aspx?scid = kb;en 183771 If you need it per user for some reason, you need to add the registry entries manually. If you have entries in both locations, HKEY_CURRENT_USER takes precedence. However, I have maybe the HKCU part came later. (Which seems to mean, mr_u., that your bloated HKCU Registry is probably less than useless. :) I just tried it on XP+SP2 and it does Application NOTFOUND OpenKey HKCR \ Excel.Application SUCCESS Key: 0xE61245A8 QueryKey HKCR \ Excel.Application SUCCESS Name: \ REGISTRY \ MACHINE \ SOFTWARE \ Classes \ Excel.Application OpenKey HKCU \ Excel.Application \ CLSID NOTFOUND OpenKey HKCR \ Excel.Application \ CLSID SUCCESS Key: 0xE163CD80 QueryKey HKCR \ Excel.Application \ CLSID SUCCESS Name: \ REGISTRY \ MACHINE \ SOFTWARE \ Classes \ Excel.Application \ CLSID OpenKey HKCU \ Excel.Application \ CLSID NOTFOUND QueryValue HKCR \ Excel s CreateObject-call does something diffferent "at its higher layer") - after one "manually" provided the registry with appropriate entries in HKCU. . . No time currently for that, maybe some nice guy can do such a test. . .?

Registry search and replace C++ / VB Need some help creating a vbs file that will replace a server name with another server name and traverse the entire registry, all KEYS and VALUES. Needs to be non-prompting, silent and easily set with the If End Sub VBScript Discussions Error (1) Recursive (1) XP (1) CreateObject (1) GetObject (1) Registry (1) Binary (1) Array (1) So, you want us to review a 200 line script of whitespace, along with some comments. Perhaps this script is capable of making changes to registry values somewhat along the lines of what you are trying to do. But just to code to do that would be a significant task. As to changing (i.e. renaming) registry keys, you seem to be asking for trouble. Suppose the registry contains keys named "homer" and "marge", and the server names in question happen to be that if you ever get this script working to the point where it modifies the registry, that running it will disable the computer. Good luck with that. / Al I dont see postings from people who cant write their full name. . .
