As this is a concurrency problem it's kinda hard pointing out the problem without seeing the whole scenario. However to demonstrate the problem, do the following: 1. Create a test table and insert data into it CREATE TABLE Test ( a NUMBER PRIMARY KEY NOT NULL ); INSERT INTO Test VALUES (1); COMMIT; 2. Now in this session start a transaction and delete the rows. Leave the transaction open -- SESSION 1 ALTER SESSION SET ISOLATION_LEVEL=SERIALIZABLE; DELETE FROM Test; 3. Start another session and select data from the test table in serializable mode -- SESSION 2 ALTER SESSION SET ISOLATION_LEVEL=SERIALIZABLE; SELECT a FROM Test FOR UPDATE OF a; 4. The session 2 hangs and waits for the result from session 1. Now go back to session 1 and commit the transaction: -- SESSION 1 COMMIT; The result in session 2 is: SELECT a FROM Test FOR UPDATE OF a * ERROR at line 1: ORA-08177: can't serialize access for this transaction Hopefully this clarifies the problem.

hi, yes document.getElementById("buttonid") is returning an object in both IE and Firefox.The problem only is that i had to fire the click event of the button using the click event in the javascript which is i think is not supported by FF.

There is no cross compliant direct equivalent of window.openPopup() method. Its IE only. If you want to emulate the behavior of 'window.openPopup()', use 'window.open()' along with any 3rd party Javascript Drag and Drop (D&D) API. HTH Jinal Desai - LIVE Experience is mother of sage....

It is in java I want to built the application in .net any idea

I don't know why you get E_FAIL but have you tried getting more information, if it's available, using the COM mechanism IErrorInfo? HRESULT hr; CComPtr spErrorInfo; hr = GetErrorInfo(0, &spErrorInfo);

Hi, By Size I mean the size of the File like recording 1 minute video produces AVI file of 1GB .I want to compress the File Size. Thanks

kjsl2k9 wrote: also the Size of File for AVI files is very large when saved avi files are not compressed, therefore they are large. I don't know what avicap32 is, but for the files to be smaller, you'd need to have some sort of codec installed, and to use it in your capture. kjsl2k9 wrote: .But when the form is minimized the Video is not saved This is somewhat meaningless. You don't even tell us what video you're capturing, I don't see how we can help based on this. kjsl2k9 wrote: Is there any free dll which can be used in the Application. Ultimately, you can do video capture using DirectX, and there are plenty of C# DX wrappers. Christian Graus Driven to the arms of OSX by Vista.

I've never seen any kind of method in any library that changes the refresh reate of a web cam. But, that doesn't mean there isn't one in the SDK that should be provided by the manufacturer of the webcam that you're using.

Hi, I had used the formula for calculating the Lat and Long by first calculating the dX and dY and then applying the following formula : - public point XYtoLatLong(float X, float Y) { float Lat = LAT0 + dY * Y ; float Long = LONG0 + dX * X ; point pnt = new point(X, Y, Lat, Long); return pnt; } where X and Y are the points of the picture box where the mouse is moved , Lat0 and Long0 are calulated as : - delX = (maxLONG().LONG - minLONG().LONG) / (maxLONG().X - minLONG().X); delY = (minLAT().LAT - maxLAT().LAT) / (minLAT().Y - maxLAT().Y); lat0 = maxLAT().LAT - maxLAT().Y * dY; long0 = minLONG().LONG - minLONG().X * dX; maxLat and maxLong are used for getting the maximum Lat and Long but the Lat and Long I am getting is giving the error of -0.00478 in Lat and +0.00389 in Long.How can I remove the Error. Thanks
