MY Scenario is Like this Actually I am writing a DB code in MFC DLL, I need to get return value from this MFC dll to a Win32 DLL i,e I should call MFC DLL inside win32 DLL and get the return value back to Win32.

hi, thanks for ur reply.. i want to call a MFC exe from another exe , so that i used shellExecute() to run another exe, at the same time ,i need to pass some parameter values to the another exe, which has to display the values in their corresponding edit box. for e.g., if i passed "NAME","NUMBER","MARK1" the another exe display those above information in their edit box. :) Try again and again, At last you will say I don't know the meaning for impossible.,.

hi, I have one clarification, I just want to know how to call stored procedures in CDaoDatabase. After the submit button I need to call one stored procedure by name STORE_PROCEDURE1 with input parameters as name,no,mark1,mark2 By using ADO I think we can use like this below. I just want to know how to use in DAO. With AdoComm .CommandText = "{call PROEX.KPP_LFE.PPP_INSTPP_EMBARQUE_AUX(?)}" .CommandType = adCmdStoredProc Set AdoParamRet = .CreateParameter("Retorno", adBSTR, adParamInputOutput, , vfRsEmb) Call .Parameters.Append(AdoParamRet) .Properties("PLSQLRSet") = True Set vfRsEmbRet = .Execute i want to do the same thing in DAO using CDaoDatabse Try again and again, At last you will say I don't know the meaning for impossible.,.

i want to store a image file into "BLOB" value in ORACLE databse. & i used COleVariant to store the byte array of image file. but when i try to insert into the oracle db , it through a error "Data type Conversion error" it's working fine for MSACCESS db using the same COleVariant class.. can u please help me for the same.. it's very urgent .... send reply -- modified at 3:03 Saturday 10th June, 2006

tnx for ur reply, but COleVariant is used to store the "OLE object" datatype in .MDB database. when i use oracle DB , the corresponding BLOB datatype is not get matched with COleVariant class in VC++. I got the error like " Data type conversion error" can u please send the details to store the oracle BLOB value throuh VC++.

hi, i develop one application in VC++-MFC 6.0 , this application is responsible for inserting image into the database (oracle)-ODBC. but when i try to insert a image file , it through a error like "Data type conversion error." //////////////////////////////////////////////////////////////////////// CDaoDatabse db; CDaoRecordset recset(&db); void CDBODBC::InsertintoDB(); { CByteArray BlobFile; BlobFile.RemoveAll(); // I clear the Array CFile aFile("image.jpg",CFile::modeRead); BlobFile.SetSize(aFile.GetLength()); aFile.Read(BlobFile.GetData(),aFile.GetLength()); aFile.Close(); COleVariant aVar(BlobFile); CString Sql = "SELECT * FROM sample3"; db.Open("abc",FALSE,FALSE,"ODBC;UID=abcWD=abc;DSN=abc;"); recset.Open(AFX_DAO_USE_DEFAULT_TYPE,Sql,dbAppendOnly); // bool b=recset.CanUpdate(); recset.AddNew(); recset.SetFieldValue("[num]","6"); //varchar field recset.SetFieldValue("[photo]",aVar); //BLOB field -image field recset.Update(); recset.Close(); db.Close(); } ///////////////////////////////////// it works for Access database .. but i got error in oracle...

tnx, but , it is MSACCESS database with the column datatype of "OLE Object" so using COleVariant class,we convert the image as bytestream to COlevariant.. but i want to do the same thing for oracle ..with the column datatype "BLOB" here also i create same COleVariant ,but it doesn't acceptable by database field "BLOB".....
