Resetting a PChar variable
- by scott-thornton
Hi,
I don't know much about delphi win 32 programming, but I hope someone can answer my question.
I get duplicate l_sGetUniqueIdBuffer saved into the database which I want to avoid.
The l_sGetUniqueIdBuffer is actually different ( the value of l_sAuthorisationContent is xml, and I can see a different value generated by the call to getUniqueId) between rows. This problem is intermittant ( duplicates are rare...) There is only milliseconds difference between the update date between the rows.
Given:
( unnesseary code cut out)
l_sGetUniqueIdBuffer: PChar;
FOutputBufferSize : integer;
FOutputBufferSize := 1024;
while( not dmAccomClaim.ADOQuClaimIdentification.Eof ) do
begin
// Get a unique id for the request
l_sGetUniqueIdBuffer := AllocMem (FOutputBufferSize);
l_returnCode := getUniqueId (m_APISessionId^, l_sGetUniqueIdBuffer, FOutputBufferSize);
dmAccomClaim.ADOQuAddContent.Active := False;
dmAccomClaim.ADOQuAddContent.Parameters.ParamByName('pContent').Value := (WideString(l_sAuthorisationContent));
dmAccomClaim.ADOQuAddContent.Parameters.ParamByName('pClaimId').Value := dmAccomClaim.ADOQuClaimIdentification.FieldByName('SB_CLAIM_ID').AsString;
dmAccomClaim.ADOQuAddContent.Parameters.ParamByName('pUniqueId').Value := string(l_sGetUniqueIdBuffer);
dmAccomClaim.ADOQuAddContent.ExecSQL;
FreeMem( l_sAuthorisationContent, l_iAuthoriseContentSize );
FreeMem( l_sGetUniqueIdBuffer, FOutputBufferSize );
end;
I guess i need to know, is the value in l_sGetUniqueIdBuffer being reset for every row??
