sql server connect : DMO SQLServer->Connect failed for user name with special characters
If I give a user name or password having special character (mainly semi-colon) then I cannot connect to the SQL Server. Following is the error: Login failed for user 'a`~!@#$%^&*()_+|-=[]'. TCP Provider: An existing connection was forcibly closed by the remote host. Communication link failure Invalid connection string attribute However, this error was coming in my Cpp code. I tried with VB, I works. Also, I got same error from Enterprise Manager. Is this a defect or known behavior in DMO? TIA, Ajey
Actual user name was a`~!@#$%^&*()_+|-=[];',./{}:"<>?

/ is an escape character in cpp, you have to replace / with // in your
string for it to work properly. hth -- Vikram Vamshi Database Engineer Eclipsys Corporation [quoted text, click to view] "Ajey" <ajey5@hotmail.com> wrote in message news:OqwRXccjFHA.3316@TK2MSFTNGP14.phx.gbl... > Actual user name was a`~!@#$%^&*()_+|-=[];',./{}:"<>? > > "Ajey" <ajey5@hotmail.com> wrote in message > news:ujnaqXcjFHA.1428@TK2MSFTNGP10.phx.gbl... >> Hi, >> If I give a user name or password having special character (mainly >> semi-colon) then I cannot connect to the SQL Server.

I think it's mainly due to semi-colon. The error message displays the user
names till the character before the semi-colon. Also, same username & password does not work while registering the sql server using Enterprise Manager or connecting through Query Analyser. - Ajey [quoted text, click to view] "Vikram Vamshi" <vikram.vamshi@online.eclipsys.com> wrote in message news:uMKZSCkjFHA.3900@TK2MSFTNGP10.phx.gbl... >/ is an escape character in cpp, you have to replace / with // in your >string for it to work properly. > hth > -- > Vikram Vamshi > Database Engineer > Eclipsys Corporation > "Ajey" <ajey5@hotmail.com> wrote in message > news:OqwRXccjFHA.3316@TK2MSFTNGP14.phx.gbl... >> Actual user name was a`~!@#$%^&*()_+|-=[];',./{}:"<>? >> >> "Ajey" <ajey5@hotmail.com> wrote in message >> news:ujnaqXcjFHA.1428@TK2MSFTNGP10.phx.gbl... >>> Hi, >>> If I give a user name or password having special character (mainly >>> semi-colon) then I cannot connect to the SQL Server.

Also try to put quotes around the user name (try both single quotes and
double quotes, one of them should be able to handle special characters) hth -- Vikram Vamshi Database Engineer Eclipsys Corporation [quoted text, click to view] "Ajey" <ajey5@hotmail.com> wrote in message news:uZXxuFojFHA.2644@TK2MSFTNGP09.phx.gbl... >I think it's mainly due to semi-colon.

Can you post your cpp code that can reproduce the issue?

strSQLLoginName = L"abc;xyz"
strSQLLoginPassword = L"abc" HRESULT hrConnect = spServer->Connect( rkstrCurrentServerName.c_str(), strSQLLoginName.c_str(), strSQLLoginPassword.c_str() ); This code also gives the same error. Also, if i paste user name as abc;xyz in Enterprise Manager or Query Analyzer I get the same error. The same thing works with ADO. I had to just escape the special characters in the connection string. While can pass the username & password directly to the ADOConnection->Connect() method. But same is not working on DMO.
