Hi, have you ever had the problem, that a Debug build works on windows and the Release does not? The problem is an access violation during appending items to a combobox.
I tried to disable optimization, without success. It's difficult to provide a patch now, because the changes are not small. Here is the problem line. I've also tried to remove "if(connection->pgAgentMinimumVersion(4))". I've included the upper section (pga_jobclass) to demonstrate the similarity of the code - this works well! I've added the cbEmailNotType-Combobox to the xrc file and also a pointer to it. Have I forgotten something important, that is required for a successful release? File: dlgJob.cpp #define cbEmailNotType CTRL_COMBOBOX("cbEmailNotType") .... pgSet *jcl=connection->ExecuteSet(wxT("SELECT jclname FROM pgagent.pga_jobclass")); if (jcl) { while (!jcl->Eof()) { cbJobclass->Append(jcl->GetVal(0)); jcl->MoveNext(); } delete jcl; } if(connection->pgAgentMinimumSchemaVersion(4)) { pgSet *mnk = connection->ExecuteSet(wxT("SELECT jmntypename FROM pgagent.pga_jobmailnottype")); if(mnk) { while(!mnk->Eof()) { *cbEmailNotType->Append(mnk->GetVal(0));* mnk->MoveNext(); } delete mnk; } } If there is not an obvious reason, I will send a complete patch until weekend.
