I am writting a PC-POS program that runs 24 hours a day (hopefully). At some point during the night it sends to a designated master PC the sales data for that day. During this time period I would like to check if a later version of the application is waiting to be copied from the master PC.
If I use the CopyFile() function it fails because the program is running on the PC-POS unit and so cannot overwrite itself. I was thinking about using WININIT.INI or MoveFileEx() with the MOVEFILE_DELAY_UNTIL_REBOOT flag, but I realy do not want to reboot the machines (16 shops with upto 4 PC-POS units in each shop).
So how would I go about starting the new version of the application without restarting the machine.
Thanks in advance.
Joe.

Pretty simple: copy the new version to a temp file - proggy.new - and then start another program to do the copy and exit the first. This other program - copyupdate.exe - would back up the previous exe, rename/move the new one, and start the new exe, and then exit.
You could also do this with a little DCOM magic, but the above is the simplest to do and debug.

Use this functions:
WritePrivateProfileString,
GetPrivateProfileString
see MSDN Chapter: PlatformSDK/Base Services/Registry/Registry Reference/Registry functions

Hi!
I am an engineering student from India, and am working on a project in Visual Basic-6.0. I need a little help with my project, and have gone through a lot of sites to solve my problem, but to no avail.It was then that I stumbled on to this site, and decided to set up a message.
Well a part of my project needs to acquire data from an ADC(Analog to Digital) card connected to the serial port and plot the data in real time.The only two controls which I can think of are MSComm and MS Chart.But I have a few questions as I have never worked with these controls before.The questions are as follows -
1. Is it possible using MS Chart to plot data in real time?
If not - Is there any other way-Maybe something like an activeX control available which could help me in real time data acquisition?
If it is - how do I go about it?I mean do I use dynamic arrays?If so, then how do I redimension them at run time?
2.Is it possible to set cursors(in the form of horizontal and vertical lines) on the plot?
3.Can I acquire data through an MSComm control from an ADC card and store it in a dynamic array?I want to avoid the modem.
Well, lots of questions , but no answers.I would really appreciate your help.Thanks for your time!!
Regards,
Alok Pradhan.

Hi,
I'm wanting to detect (on a mouse move) whether the mouse is over a popup menu (for which I have a handle). Does anyone have any ideas about how to go about finding the size and position of a menu on the screen, or even just doing a hit test? I cannot find anything in any documentation, but am probably looking in the wrong place!!!
thx

You'll get a WM_MENUSELECT message when the mouse moves over or off a menu item.

I only seem to get this message when moving onto the menu item, not when it comes off (which is what I really need). MenuItemFromPoint sounds like it should do what I want, but it gives incorrect results under NT, although seems OK under '98.
Has anyone else had any trouble with MenuItemFromPoint?

While using 'DLL' created with 'VC++' in VB i am getting an error "Bad DLL calling convention".
Is it the problem with declaration of Calling conventions in vc++?
How to avoid it?
|
|
|
|
|
I don't know VB, but you need to export the function with the calling convention that VB uses. Since the default in VC is __cdecl, I imagine the right convention is __stdcall. For example:
extern "C" __declspec(dllexport) void __stdcall MyFunc() {}
(The order of the tokens may be off - I never can remember which one goes where.)

I feel a little sheepish asking this but could anybody pl. write an easy to follow beginners article on using source control. E.g. I'm a student developer who rarely uses source control at home for code and stuff cause I think I'll get a heartburn going through documentation. Show me the easy way out + tips and tricks for easy usability.
Thanks a bunch.

Hello,
I was wondering if anyone knows of a way to get some kind of system id from a PC. I've looked at:
- GetVolumeInformation to get the hard-drive serial number but this is often the same if drives are ghosted from the same image.
- Netbios to get the MAC Address of the Ethernet Adapter. The problem is that Microsoft says that this "does not work reliably on Windows 95 or Windows 98".
Thanks,
Raed

Heres the deal,
Marketing want's a web view (IWebBrowser2) in a property page of a wizard in my app (piece of cake).
The web page to be displayed will contain a FORM section with a bunch of yet-to-be-determined input controls with a "hidden" submit button - they want the data to be sent when some other control outside the IWebBrowser2 is activated (the apply button).
The big question is - how do I programaticaly "click" on the submit button?
1) Is there a way to directly access the submit functionality with ease?
2) Or do I need to enum all the items and data in the FORM section and compose a custom IWebBrowser2::Navigate call?
Thanks for any help.

I have created two exes(MFC).I am posting a pointer to the structure thro' PostThreadMessage
from one exe
(struct message
{
int messageid;
CString messagedescription;
};
the members are initialized
)
The other exe should receive the pointer posted by the thread from other exe & it should display the member values.But, in my case the structure is getting posted successfully !But, I am getting some junk values in the receiving exe.
How can I get the desired values, then ?

You can't pass data between different programs like that. Each program has its own address space, and pointers in one app don't make sense in another app.
Either switch to WM_COPYDATA or use memory-mapped files.
