Changing the User account of a Service dynamically - C / C++ / MFC Discussion Boards

i am using dshow to play a video. (i am using dx9)

top of my project, i set,

#include <dshow.h>
#include <d3d9.h>
#include <vmr9.h>

...

in Debug, the program runs successfully,

when i changed to release, it has link error,

error LNK2001: unresolved external symbol _CLSID_NullRenderer
error LNK2001: unresolved external symbol _IID_ISampleGrabber
error LNK2001: unresolved external symbol _CLSID_SampleGrabber
error LNK2001: unresolved external symbol _IID_ICaptureGraphBuilder2

when i change Debug again, it can not be complied with the link error also.

Buddy, it would be better you ask this question in WIX support forum, here i believe very few people are aware of this installer, generally people prefer installar shipped with VisualStudio or MacroVision Installshield on paid side and Innosetup on free side.

Hi,

I have created a service not specifying the username/credentails i.e. local-account. I am trying to change the user to "domain\username" dynamically using ChangeServiceConfig API. This API always returns me error code 87 i.e. “The parameter is incorrect”.

I have explained the problem below. Does anyone why this behavior?

I have detailed the steps below:

I have an issue. I create a service under the local system account. After that I am trying to change the user to domain\user. E.g.: if my domain name is “MSDN” and username name is “me”, I am trying to change the user credentials to “MSDN\me” using the ChangeServiceConfig API. This API is always throwing me an error 87 i.e. “The parameter is incorrect”.

#define SZSERVICENAME “Trial”
ServiceCreate()
{
schSCManager = OpenSCManager(NULL, // machine (NULL == local)
NULL, // database (NULL == default)
SC_MANAGER_CONNECT | SC_MANAGER_CREATE_SERVICE // access required
);

schService = CreateService(schSCManager, // SCManager database
TEXT(SZSERVICENAME), // name of service
TEXT(SZSERVICENAME), // name to display
SERVICE_ALL_ACCESS, // desired access
SERVICE_INTERACTIVE_PROCESS|SERVICE_WIN32_OWN_PROCESS, // service type
SERVICE_AUTO_START, //SERVICE_DEMAND_START start type
SERVICE_ERROR_NORMAL, // error control type
szPath, // service's binary
NULL, // no load ordering group
NULL, // no tag identifier
TEXT(SZDEPENDENCIES), // dependencies
NULL, // LocalSystem account
NULL); // no password
}

ChangeServiceParms()

{
//Domain = “msdn.try.com”, computer name is “comp”
LPTSTR szServerDNS = “comp.msdn.try.com”;//Fullname of the computer
LPTSTR szAccountDN = “MSDN\me”;// User to which I am trying to logon
schSCManager = OpenSCManager(szServerDNS,
NULL,
SC_MANAGER_CONNECT );

BOOL success = ChangeServiceConfig(service,
SERVICE_NO_CHANGE,
SERVICE_NO_CHANGE,
SERVICE_NO_CHANGE,
NULL,
NULL,
NULL,
NULL,
szAccountDN,
NULL,
NULL);
if(!success)
{

DWORD err = GetLastError();
}
}

Hi all,

I would like to install and configure the postgresql from my MFC code! If it is possible?

Thanks in advance

I basically have three group boxes.
The first group box has 2 radio buttons with labels reading “Choice A” and “Choice B”
The second group box is entitled “Choice A” and has several radio buttons within it.
The third group box is entitled “Choice B” and has several radio buttons within it.

I basically start off the program with group boxes “Choice A” and “Choice B” and their contents invisible.

Now, what I can’t figure out is:
When I click “Choice A” in the first group box, I want the “Choice A” group box and its contents showing up (with “Choice B” and its contents still invisible) and vice-versa.

I don’t necessarily need code, just a push in the right direction.

I’ve looked at several tutorials involving adding member variables and such to the radio buttons, but the tutorials were for an older version of Visual C++ and the ClassWizard has changed enough to cause conversion issues when I (attempted to) follow along.

However, I’m hoping the answer will be a simple “on push, choiceA.radiobutton1.visible=true;” type of thing.

Thanks in advance.

This seems to be C#, in VC++ I would make it like...

supposing you have member variables for every element...

If (m_rbChoiceA.GetSelect ())
{  //Showing the A group...
   m_rbChoiceA_1.ShowWindow (TRUE);   //or ShowWindow (SW_SHOW)
   //the rest of the options
;
   //Hidding the B Group...
   m_rbChoiceB_1.ShowWindow (FALSE);
   //...
}

and the opossite when B is selected.

I hope it helps you a bit, sorry but I didn't use C# yet.

BTW, I think is better to enable/disable than show/hide, I had a endless loop in OnPaint bcause of ShowWindow because it sends a "redraw" message internally.

Greetings.

“The First Rule of Program Optimization: Don't do it. The Second Rule of Program Optimization (for experts only!): Don't do it yet.” - Michael A. Jackson

Add the code below in the OnInitDialog function call
where IDC_STATIC is ID of Group box and IDC_RADIO3 the ID of the Radio Button. This may be different for your application hence needs to be changed accordingly.

<br />
	//Hiding the 2 Group Boxes<br />
	GetDlgItem(IDC_STATIC)->ShowWindow(SW_HIDE);<br />
	GetDlgItem(IDC_STATIC1)->ShowWindow(SW_HIDE);<br />
<br />
	//Hiding radio button in Group Box A<br />
	GetDlgItem(IDC_RADIO3)->ShowWindow(SW_HIDE);<br />
	GetDlgItem(IDC_RADIO4)->ShowWindow(SW_HIDE);<br />
<br />
	//Hiding radio buttons in Group Box B<br />
	GetDlgItem(IDC_RADIO5)->ShowWindow(SW_HIDE);<br />
	GetDlgItem(IDC_RADIO6)->ShowWindow(SW_HIDE);<br />

This will make sure that the 1st time you start your application, the 2 group boxes are visible.

Now handle the Single Click event of the 2 Radio buttons.

Add the following code in the "Choice A" radio button event handling function.

<br />
	GetDlgItem(IDC_STATIC)->ShowWindow(SW_SHOW);<br />
	GetDlgItem(IDC_RADIO3)->ShowWindow(SW_SHOW);<br />
	GetDlgItem(IDC_RADIO4)->ShowWindow(SW_SHOW);<br />

If you want dont want Group A radio buttons/box to be visible when you click on the 2nd radio button, please hide the same.

char** Buf[ 8 ] ;
how to allocate and use this pointer ?

Confused | :confused:

Thanks & Regards

char ** Buf[8];
int i,j;
for (i=0; i<8; i++)
{
  Buf[i] = new char * [10];
}
Buf[0][0] = "foo00";
Buf[0][1] = "foo01";
Buf[0][2] = "foo02";
//...
Buf[1][0] = "foo10";
//...
for (i=0; i<8; i++)
{
  delete [] Buf[i];
}

BTW: until you can't figure how to use it, don't use it.
BTW2: maybe hard-wired 8 as buffer size is not a good idea. Use an const instead.

Nice Work

std::vector<std::string> is pretty much better if you code in C++.

I prefer CString over std::string. as it is much easy to use than std::string and in my way more robust.

that's only your point of view. std::string is not that difficult to use, and is much more powerful when mixed with the other STL classes, especially the algorithms.

>> more robust
I don't trust this. can you give some proof about this ?

BTW, i really don't like the idea of mixing MFC and STL.
either choose std::vector<std::string> if MFC is not a must, or CStringArray, but vertainly not std::vector<CString>.

CStringArray has less capability than vector and CString Mix. this is some time called Mixed mode programming;P Smile | :)

Hello Everybody,

I have developed an MFC dialog based application which I am launching through an interactive service. The application was running fine with all its functionalities until I installed IE7 on my machine. The problem is that, I can logout safely first time after rebooting the computer, but if I tried to logout second time I get an Event ID 1073 in system event viewer and computer doesn’t logout.
Please help me out…

Thanks in advance,
Sumedh

Thanks
