What code are you trying to use to set the baud rate? What TSPI is the modem using for its TAPI functionality?
I've found this article useful for serial comms,
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp[^]
it uses BuildCommDCB for setting the baud rate.

I have a simple problem with MFC and VS6 - I want to display a progress bar whilst I'm loading a lot of data. The load happens in a method of my class, which is created under the application's document class. My simple question is - how do I get hold of the parent window needed to create the CProgressCtrl? Can I use GetFocus() somehow?
cheers

Hi
I just wanna know how i can embed SQL in C++. By the way i have this relational schema
HOTEL (Hotel_No, Hotel_Name, Address)
GUEST (Guest_No, Guest_Name, Address)
ROOM (Room_No, Hotel_No, Type, Price)
BOOKING (Hotel_No, Guest_No, Date_From, Date_To, Room_No)
Where it asks what is the total income, for the month of July 2001, from occupied rooms at all the Sheridan Hotels.
I'm trying to program it in SQL in SQL Analyzer, but i have never experienced programming with this transact SQL before. In the first instance, it is like Pascal to me, (IF ..END IF, BEGIN)Does anyone know any hints or tips regarding above problem???
All helps are highly appreciated!

You have a number of choices;
(a) write a stored procedure in T-SQL and call that from your app, passing in your date range
(b) write a select statement, and use any of OLE DB, ATL Data consumer classes, ODBC or even ESQL/C to do it
(c) Use something like Crystal Reports.
More seriously, if you want to issue a simple SQL statement, then something like the ATL classes are almost a no-brainer. There's a Wizard you can use to get you started, with a simple example, and then just tweak bits from it's generated output to go on.
It's sometimes confusing, with Accessors and commands, datasources and sessions, but read through the on-line help and it does make sense.

Hi all,
Here's my issue. I'm using CString and here's what I setting it to:
...
tempString += _T("<basefont size="" 2""="">\n");
...
yes I am building an HTML file.
The problem is with the quotes. For some odd reason, when the string is assigned into tempString ALL of the quotes are removed so it looks like this in the debug window:
<basefont size="2">
WHY? I use this method in many other places and it comes out just fine, which should be:
<basefont size="2">
Anybody have any ideas at all? I do this all over the place, but this doesn't work in one case in my application. I don't understand at all. Any help and suggestions are greatly appreciated.
Thanks!
Dan

Okay, so in a past project I had used IDL to expose a UDT i had in a dll to an excel spreadsheet. The DLL in that case was a straight C++ DLL, no MFC.
In this case I have an MFC DLL. I want to expose a UDT to the excel spreadsheet. I have tried, but it does not work. I have the UDT defined in my IDL file, but when I use "references" tool in excel, I dont have access to the type? The code is below. Am I doing something wrong here?
<code>
[
uuid(A1CCE58E-553D-4394-828C-5227D4526293),
helpstring("Topic Conversion Library For Tag List")
]
library TopicConversionLib
{
typedef struct _vb_topic_data
{
short t_num;
float t_value;
BSTR t_name;
} VbTopicData;
[
helpstring("topic stuff"),
dllname("topic_conversion.dll")
]
module topic_conversion
{
};
}

Don't you need to tag the typedef with a uuid?

How do you use the VbTopicData?

I ran a sample app for a splash screen, and now even though other apps are okay, my main app is crashing at !ProcessShellCommand(cmdInfo) whivch I stepped into, and its at the switch:
BOOL CWinApp::ProcessShellCommand(CCommandLineInfo& rCmdInfo)
{
BOOL bResult = TRUE;
switch (rCmdInfo.m_nShellCommand)
{
Another mfc program does fine! The sample I ran had a file pair: cmdline.cpp and .h.
Here are its contents:
#include "stdafx.h"
#include "cmdline.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
void CCommandLineInfoEx::ParseParam(const TCHAR* pszParam, BOOL bFlag, BOOL bLast)
{
if (bFlag) {
m_options[pszParam] = "TRUE";
m_sLastOption = pszParam;
} else if (!m_sLastOption.IsEmpty()) {
m_options[m_sLastOption] = pszParam;
m_sLastOption.Empty();
}
CCommandLineInfo::ParseParam(pszParam, bFlag, bLast);
}
BOOL CCommandLineInfoEx::GetOption(LPCTSTR option, CString& val)
{
return m_options.Lookup(option, val);
}
I dont know whats gone wrong, but none of my saved versions are working, and I know for a fact they were before I ran this sample. I actually ran another splashscreen app too, but it didnt have a file called cmdline.* (if thats the problem).
Help! I am devastated! What has gone wrong on my machine?
Appreciate your help,

My main app has the splashscreen classes in it, but the earlier versions dont. They arent working either...

Don't panic. I feel kinda guilty since it was me who directed you to the code
Have you supressed the m_pMainWnd setting in InitInstance ? That could be the cause. If this is not the problem, try erasing any trace of DiLascia's code from your project (.cpp s, .h s), delete the Debug and Release dirs and rebuild. Hope this works. Tell me back what happened.

Sorry> I didnt mean to make you feel bad - you didnt know! Besides the sample is working fine! Even if I comment out all his stuff, it crashes> What is weirder is that I have 20 old versions saved as I go along. These arent working either. So something has happened to the environment, not the code> I installed my app on a different machine(2 actually) - it works fine there. My registry looks okay too ....
A coworker is right now in the process of transferring her data onto a new pc she just got, so I''ll use her old machine till my new 2.8 gig comes in( not ordered yet). Its just very puzzling though. In the meantime I am learning about HTML help workshop, and an independent sample app that will merge databases,so I am not totally crippled....this stuff will keep me busy till I can inherit her old pc.
THis makes me so scared to try new things off the web....and yet it didnt install anything...just ran code(which did something that my app doesnt like).
Appreciate your help,
ns

Though one certainly has to be picky about about what to execute from the net, MSJ's code archive is not a hacker-candidate site
I don't have a compiler right now, but I'll try to take a look at this next Monday. In the meantime, I'm almost sure nothing critical has been broken. If you have spare time, try recreating the project from scratch and then transferring the code (and only your code).

Thanks. Thats very kind of you to offer to look at it. I have a good machine at home, so I'll be able to work on it there. Then on Tuesday (we have the coming Monday off) I'll be back to deal with this. I agree that the MSJ site is not a hacker site. But thats all I've done this morning. Please dont feel responsible for this.....I really value your suggestions and help.

Hi Joaquin,
Heres the promised update! Paul D. and I exchanged maybe a half dozen emails and he couldnt think of what had gone wrong. I was configuring another machine etc this morning and just as a last ditch effort, killed the registry entries my project makes, though it looked perfectly uncorrupted. To my unexpected delight, that resolved the problem! I rebuilt the keys and all is well (until I crash again - just a matter of time! ) Anyways I did not expect that would be the resolution. I am so relieved as you might guess! So thanks for the moral support> I even have to nerve to re-undertake the splash screen effort again, though not with P D's class...
Thanks again and I hope that you will still in the future point me to useful resources. I value your responses tremendously!
Sincerely,
ns

Hi
I issued this problem recenty but now I know a bit more about its nature.
I'm trying to store some data in MsOffice files and the problem is that MsWord 2000/XP removes my data after I save document from the Word (I tried also MsWord 97,MsExcel 97/2000/XP and here my data remains untouched). Now some explanation how I store my data in doc file:
1. Using StgOpenStorage I open office file as a compound file
2. I create new storage with IStorage::CreateStorage
3. Within newly created storage I create new stream using IStorage::CreateStream
4. I store my data within newly created stream using IStream::Write
5. I release all opened streams and storages
I discovered that when in doc file Word adds stream 0Table (1Table is probably always present) my data doesn't dissapear (I don't know why). I don't know how to prevent Word from deleting my data but I suppose that forcing Word to add 0Table stream could solve my problem (but how can I do this). I would appreciate any hints.
