Truly aopreciate it. Hopefully my execute statement wont choke. For example, I cant get past a crash when i do an insert into in an execute statement. Its really frustrating! I pConn->Execute or PCommand->Execute or even pRecordset.OPen(pCommand,...) All three crash. SO hopefully your sql wont crash. ANy ideas why?
If you are into SQL and db, can you point me to some Working code for addnew or insert into? Theres tons of stuff out there - nothing works. AT best addnew() works, says recordcount is increased, but no records added to the db are visisble. The rs is lockoptimistic and adkeyset. It can edit just fine, but not add..
Thanks,
ns

Are you using RichEdit 2.0 (riched20.dll) on the NT machine?

Hi,
I would like to read IP address of my DeskTop to prepare some Internet link! But I do not have the Iphlpapi.h & I can not download the SDK Platform from Web (Can nor ceate Server object even I restart PC several times)
Any one know how we can work around without using Iphlpapi.h to search for IP address?
I appreciate any one can provide any information about this!
Thanks & regards,

Hi,
I'm sort of a beginner at MFC, and have taken a mammoth dialog from my project and attempted to convert it to a tabbed interface using CTabCtrl. Everything works on the child dialogs except for my combo boxes, which are drop-down style straight from the ClassWizard. They worked fine on the main page. Now, the lists will not drop down at all on my XP system, and only a blank list drops down on my W2K system (not sure why). The lists are the proper size.
If the problem is that the list portion of the combo box is a child of the desktop, is there a workaround?
Thanks in advance for any help,
- Fran

i have only used CPropertySheets to do tabbed interfaces, but what you probably need to do is have a function get called whenever a tab is selected.. like a notify event.. whenever a tab(dialog) gets this notify event it should call m_cbMyCombo.ResetContent() and then m_cbMyCombo.InsertString() for each of your items..
what probably happens is that the OnInitDialog() is only called once (or maybe not at all) for each of the tabs(dialogs).. so you should call a function to populate them everytime that tab is selected..
hope im somewhere on target..

Hi dz,
Thanks! I was dubious (sorry), but that did the trick. What a relief. I already had OnSelChangeTab() handling tab selection, so all I had to do was insert the ResetContent() and InsertString() calls as you suggested.

i have a combobox which has the sorting function turned on.. but i am dynamically populating it all the time and it doesnt ever sort them.. is there something i can do to make it sort the text strings in the combobox after I've added all of my items? ive tried myComboBox.Redraw() and myComboBox.Invalidate()
thanks for any suggestions!

Have a look at CComboBox::CompareItem

i dont follow.. i have tried looking at this function on msdn, but this function appears to just compare 2 items, i would be have to sort before i populated the combobox each time..
i was kinda just hoping to call the sorting which is already built in.. it has sort turned on.. but it isnt sorting when i add items.

How are you adding items to the combobox? If you use InsertString(), they won't be sorted, as you're specifying a position. If you're using AddString() (and CBS_SORT is set) they should automatically be sorted.

my question regards the MS browser control , but this seemed the most appropriate forum.
Does anyone know whether it's possible to affect the security domains of windows and frames presented within the browser control selectively - eg. for different window instances to possess alternate security levels. I'd like to develop a BC based app. that possesses security characteristics similar to those of an HTA. This is primarily to allow script originating from one domain to affect pages from a foreign domain without providing the foreign domain a 'Trusted' status relative to the top level window. Essentially I'm trying to get the BC instance to behave like an HTA.
Any advice a/o leads on resource will be appreciated - I'm new to windows development.
Thanks

I've been asked to write a program that will start another program up and then log all calls it makes to WriteProcessMemory() and any changes it makes to its variables. Is this even possible and if so where would be a good place to start looking?
Thanks
|

Intercepting WriteProcessMemory() is possible using API hooking techniques. (There are articles about this here at Codeproject.)
However, WriteProcessMemory() is usually used only to modify memory in foreign processes. If you need to monitor what the process does on its own address space you are nearly out of luck. This means that you have to write a debugger that connects to the target process, halts all threads and single steps them to monitor the changes. Really, really hard work!

Thanks for the reply, sounds nasty. Might have to tell the guy that its going to take a while if it'll be done at all. I wasn't expecting it to be easy to check the variables of another process but that sounds a little out of my league just now, maybe in a couple of years 
Thanks again

I think he miss-read your question. It is nasty to do that to the program's own process, but your program is going to start another program with the CreateProcess function, right? If that's the case then it won't be as hard as because you your program can intercept all the other programs messages amd can easily log it. Look for windows hooks at msdn.microsoft.com.

What value can you get out of this output, seriously curious here. Is the idea to detect memory flaws in a programs process? How do you analize this?

Maybe something like BoundsChecker would work for you.
When someone asks you for the impossible maybe it's time to ask them what they really want.

hehe, thanks for all the help guys, more pointers are always welcome
My program would be starting the other process up so I'll take a good look at hooks(thanks). The main reason for doing it is because there is a group of us working on a set of programs. We're all students and bored doing the usual 2nd year programming stuff so we're writing some other games and apps and taking requests from local businesses for fun.
Just now the way we work it is that we have everyone send in the executables once they're finished their programs but we're trying to get this program and the ftp site-to-site program up and running to make life easier. Because we don't send the sources around we like to be able to check that our programs are working on others machines as well so we can then pass them on.
Anyway, thanks for the tips and keep them coming if anyone knows the solution to my CFtpConnection::Command problems feel free to help

What does that mean? The messagebox appears and it goes into assembly debugging, i'm trying to enumerate all the available compression driver on the system, here's the code:
void onConvert()
{
acmDriverEnum((ACMDRIVERENUMCB)listCallback, NULL, ACM_DRIVERENUMF_DISABLED);
}
BOOL WINAPI listCallback(HACMDRIVERID hadid, DWORD dwInstance, DWORD fdwSupport)
{
if (fdwSupport == ACMDRIVERDETAILS_SUPPORTF_CODEC)
{
ACMDRIVERDETAILS details;
int box;
int test;
details.cbStruct = sizeof(details);
box = acmDriverDetails(hadid, &details, NULL);
SendMessage(GetDlgItem(ghWnd, IDC_CODECS), LB_ADDSTRING, 0, (LPARAM)details.szLongName);
}
return true;
}
First i call the onConvert and then it uses the listCallback function to enumerate the different drivers.
Thanks in advance

Hm...
- Did you placed a breakpoint on the very first statement of your listCallback?
- The cast to ACMDRIVERENUMCB for the first parameter to acmDriverEnum() should not be necessary. If the compiler complains about it, there is something wrong.
