Article #10347: Programmatically Changing the IDAPI.cfg

Question: How do I change settings in the IDAPI.cfg file programmatically in C++?
Solution: You need to use the DbiOpenCfgInfoList BDE API call. The following code example is a function that will take in a path to the part you want to change, and a value that you want to change it to.
Code: void __fastcall SetConfigParameter(String Param, String Value){

hDBICur hCur;

DBIResult rslt;

CFGDesc Config;

String Path, Option;

bool Found;

char Temp[256];

hCur = NULL;

Found = false;

if (Param.Pos (";") == 0){

ShowMessage (String ("Invalid parameter passed to function. There must ") +

String ("be a semi-colon delimited sting passed"));

return;

}

Path = Param.SubString (0, Param.Pos(";") — 1);

Option = Param.SubString(Param.Pos(";") + 1, Param.Length () — Param.Pos (";"));

Check(DbiOpenCfgInfoList(NULL, dbiREADWRITE, cfgPersistent, StrPCopy(Temp, Path), hCur));

do{

rslt = DbiGetNextRecord(hCur, dbiNOLOCK, &Config, NULL);

if (rslt == DBIERR_NONE){

if (StrPas(Config.szNodeName) == Option){

StrPCopy(Config.szValue, Value);

Check(DbiModifyRecord(hCur, &Config, false));

Found = true;

break;

}

}

else{

if (rslt != DBIERR_EOF){

Check(rslt);

}

}

}while (rslt != DBIERR_NONE);

if (Found == false){

ShowMessage (Param + " entry was not found in configuration file");

}

if (hCur != NULL){

Check(DbiCloseCursor(hCur));

}

}
