I have built a program utilizing ADO to pull data from an Access Database. I am having problems taking this data which is formated as a _variant_t data type to a floating point array in C++. The following is the initial format of the array and the process that is attempting to populate this array. Can someone help me with a good source to learn about these conversions? Secondly, can someone help me with the proper code for the array so that it can be populated? At the bottom is the error message I am getting.
const int arraySize = 5000;
_variant_t OpenArr[arraySize];
ADODB::_RecordsetPtr recOpen = NULL;
while(!recOpen->EOFile)
{
record++;
Open = pOpenField->Value;
Open.ChangeType(VT_R4);
printf("Data_Open: %4.5f\n", Open.fltVal);
printf("Record: %d\n", record);
OpenArr[record]=recOpen->GetRows(-1,0);
recOpen->MoveNext( );
}
Data_Open: 1.41283
Record: 1
Error
Code = 800a0d5d
Code meaning = U
Source = ADODB.Recordset
Description = Application uses a value of the wrong type for the current operation.

Have you Googled for 800a0d5d?

Have you tried other arguments to GetRows()? I've never used it, but -1 looks odd as the number of rows to retrieve.

My bad. I was using a slightly aged version of MSDN.

Hi all,
i am working on an MFC application, just a small dialog to take password input from user...
once the password has been entered in the edit box, if i click ENTER(IN KEYBORAD) a new character is appended to the password..
if i click manually on the OK button in the dialog things work properly.....
So could i get some help on how to solve this issue so that once the user types the password and hits ENTER in KEYBORAD, the action is performed which should happen on OK button clicked on the dialog...
Thanks...

did you set multi-line property to edit box? that can be one reason.

Check out the ES_WANTRETURN and ES_MULTILINE styles.

Use an installation package like InstallShield.
It supports upgrade, removal etc.

The latest version of our software suddenly started running slowly and being generally erratic.
We traced it to our dongle heartbeat timer routine. Though we set it to 90s, somewhere else the same timer ID seems to be set to a few milliseconds.
We have several third party components. Is there anyway to find out the source of the rogue SetTimer?
Edit to clarify....
We still get the 'fake' OnTimer message even if we disable all of our own timers...
|
|
|
|
|
Why don't you create unique IDs for you timer and do processing only after checking the ID?
|
|
|
|
|
We do exactly that - but one of our third party components was using the same ID. The ID is just an Int so you can't guarantee it won't be used by someone else.
Still, I figured out what was causing it and decided the easiest way to fix it is to change our timer IDs.
|
|
|
|
|
But timers can be made based on a Window handle.
I'm guessing you're not doing that.
|
|
|
|
|
We are - but peculiar to the way we implement stuff we 'share' our main frame hWnd with a third party CAD engine, and thus ran into a conflict...
|
|
|
|
|
Aha!
For a Window, you must have unique timer IDs.
So, as you've done, changing the ID is the solution.

Im throwing this question out there and seeking any direction
anyone can give me. I think I would die for a sample project that
perform just some steps and I can finish it from there.
Go to this link:

From a visual C++ program, is there a way to programmatically click on
'District of BK v4.1 RC2 [10/20/10] - Live - Document Filing System'. Then you get
to a screen asking for a login and passcode. I have that data. Is there a way to
programmatically type in that data and hit Login.
There other screens ask you for your name, address and so forth.
Is there any way to type in this data programmatically rather than manually go to this
link and doing it each step at a time?
Please let me know.
Sincerely,
Danielle Brina (an oveworked graduate student)

I've done this very thing with VB Script before, but not VC++.

Hmm... I havent work with basic for along time. How hard is it with VB?
Is there a way of sending a sample project or script that could do this?
I can use ShellExecute to run something. Can I ShellExecute a VB script?
Please let me know.

I've not ever tried, but I would not be surprised if you could.

You can get more information in the call stack if you have the corresponding .PDB files for the binaries.
