Don't you need two \ characters for literal character strings?
"c:\\Program Files\\Windows Live\\Messenger\\msnmsgr.exe",

I checked your code against mine and see the following differences:
- Creation flags. I use: normal_priority_class+CREATE_NEW_PROCESS_GROUP
- I use CreateProcess(NULL,"C:\Program files....". Thus turn the first 2 arguments.
- Try parent starting directory "c:\Program Files\Windows Live\Messenger". Or try to run something in the windows folder. Guess that the folder is not accessable. As mentioned try to run
it manually from the commandline.
- Set si.wShowWindow to SW_SHOWNORMAL
Does this help?

Follow the suggestions by Garth J Lancaster and Chuck O'Toole.
In addition to those suggestions you also need to pass the command line in a modifiable array for the unicode version of CreateProcess.
Here is an excerpt from the documentation -
The Unicode version of this function, CreateProcessW, can modify the contents of this string. Therefore, this parameter cannot be a pointer to read-only memory (such as a const variable or a literal string). If this parameter is a constant string, the function may cause an access violation.

Hi,
I'll explain what I am trying to do with my project. I have created a client for a 3D world but when you click on the application the game launches but what I want is when you click on the application a login window appears so users can login to the project or create a new account with a new window.
Thanks
Andrew

And what is your doubt about?
It's just a dialog box with some text boxes and possibly static controls (and, maybe, one or two buttons...).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

It's on C++ and I am having trouble creating code for it and to connect it to a database with user accounts and that would be fantatic to have it on the project.

I hope you are using Win32/MFC or windows for creating UI.

Visual Studio can create a skeleton dialog-based application for you, either a MFC project or a Win32 one(if you use MFC the task is somewhat simpler). As for connecting to the database, you've a lot of options (personally, I like ADO), have a look at CodeProject's articles about [^].

Would it be easier if I pasted code onto here and I had one error but I don't think I have done right.

You may try.

Please excuse me if I get it wrong the first time but I will get use to it quickly. Here is the top part of the code and the area I put the CreateWindow Code.
<br />
<br />
#include <windows.h><br />
#include <windowsx.h><br />
#include <d3d9.h><br />
<br />
#pragma comment (lib, "d3d9.lib")<br />
<br />
LPDIRECT3D9 d3d;
LPDIRECT3DDEVICE9 d3ddev;
<br />
void initD3D(HWND hWnd);
void render_frame(void);
void cleanD3D(void);
<br />
LRESULT CALLBACK WindowProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam);<br />
<br />
int WINAPI WinMain(HINSTANCE hInstance,<br />
HINSTANCE hPrevInstance,<br />
LPSTR lpCmdLine,<br />
int nCmdShow)<br />
{<br />
HWND hWnd;<br />
WNDCLASSEX wc;<br />
<br />
hWnd = CreateWindow(TEXT ("Login"),<br />
TEXT ("Login"),<br />
WS_OVERLAPPEDWINDOW,<br />
CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,<br />
NULL,NULL,NULL,NULL);<br />
ShowWindow(hWnd,SW_SHOWNORMAL);<br />
UpdateWindow(hWnd);<br />
hdc = CreateDC(TEXT ("Design Results"), NULL, NULL, NULL);<br />
I need help with the textboxes, size and button for the dialog to be created. If I have got it wrong could you help me amend it.
Thank you.

In your WindowProc implementation,
you should handle WM_CREATE message and try create textboxes, button.

Can you show me how my code should look like and I will follow on and learn it for next time.

Why don't you learn it for this time?

As Chief Executive at iWorld, shouldn't your employees be handing this for you? 
You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

As a matter of fact, I did. That's why I made the comment. Hard to tell if he's being tounge in cheek or just seriously out of touch. For going to Europe's largest school, I would have hoped their English department was doing a better job.

Okay, fair point. Any chance I could have that "duffer" back - think I may need to assume that role for a little while.
Personally, I was left with the impression that it was a rather cheeky and informal tone on the site, though as you mention the spelling and grammar don't exactly put him in the queue for Pulitzer Prize winners. (not that I'll ever get one mind you)

Duffer? And I don't play golf at all. I infer that to you duffer probably means more like what dufus does to me. It did sound "cheeky" (and not the big butt meaning from this side of the pond) to me but I thought my reply could be taken either way depending on his meaning.
They do have a geek category for Pulitzer Prizes.

You should handle WM_LBUTTONDOWN event for your client application.
After that you create a window using CreateWindow or use CMyDialog for logon

Is there any code floating around anywhere or a tutorial or someone who know how to create it anywhere just to help with this.
I am using Win32.

Yes, there are lots; in books, here on CodeProject, on nearly every site in the world that offers technical support/resources. The trouble is you are too lazy to use them. The code you posted above is exactly the same (apart from the text strings) as the ones you posted previously, demonstrating that in the last few months you have not spent any time trying to learn any more about Windows programming.
I even went as far as providing you with a fully funtional basic Windows app a couple of months ago; obviously even that was too much for you to try and learn from.

Richard maybe you shouldn't be that cheeky as I don't think you know how powerful and well respectedand I am. I have close contacts with the BBC and serveral companies who are interested in sponsorship and advertising opportunities within my 3D virtaul world.
As the Chief Executive I have capabilities to learn very quickly and I am a very enthaustic individual who always puts 100% into my work, I know how to manage my employees at the company, I pay them a lot of money but I have seen a downside when they are programming they seem to have a hearing difficulty about what I require and it's really annoys me and the Board of Directors, so I've decided to take matters into my own hands.
As the saying goes "Treat others, how you would like to be treated"

This is the virtual world you created without being able to construct a simple Windows dialog.
MrMcIntyre wrote: I am a very enthaustic individual who always puts 100% into my work
And yet you cannot make the effort to learn Windows programming, even when provided with a full source code sample to help you.
MrMcIntyre wrote: I know how to manage my employees at the company, I pay them a lot of money
Your job advert here[^] says you won't pay until you have sold your product; hardly treating employees well.
MrMcIntyre wrote: so I've decided to take matters into my own hands.
Or rather you have decided to try and get CP members to do all the work for you, again.

Richard I want to clear a few things up for you as you are finding it extreemly difficult to understand this. I have over 125 employees at my company stretching over 30 countries and speaking different languages and payed around £200 - £300 per month you do not know how hard it is to communicate clearly to foreign people.
I don't mean to be rude to you but you can't tell someone what you think without actually investigating who they are first. Yes, it's true I am not very good at programming and that's exactly why I have employees so I decided to turn to CodeProject as it has great people for help and eventually I can help out my employees with things shortly, but quite frankly I haven't seen anyone who has attempted to help me.
