As usual, I checked LNK 2019 , in MSDN Apr-2001. And could not find it. With VS 6.0 its LNK 2001. Thats why asked for error message.
Though, its present in latest one. I should have checked that.

Remark from MSDN about Execute:

Execute works only for action queries or SQL pass-through queries that do not return results. It does not work for select queries, which return records.

One way is to derive a class from CDaoRecordset. Then just change the GetSQL() method (it default to SELECT *) to select those columns and rows you want.

I want to print a small bitmap image using c++ (not MFC). I don't have a problem in printing normal text. But now I want to print an image.

Sorry for incomplete information. I want to print using a standard LPT printer. for example, to print some text we can print simply by writing it into a file (naming the file as "LPT1" inside the program). But how do I print a image?

Crystal Reports 9 deployment

Anybody with experiences in deploying CR9 with an application developed in VC 6.0 please help!
I'm pulling my hair out one by one! App should be installed on win98 machines!
I'm using CR9 Crystal Report Viewer Control implemented in my app, with printing, exporting functions as well.
I build my setup package with Inno. I used all the crystal docs could find in the topic of figuring dependencies.
I already have a bunch of files installed. I know the issue with unicows.dll, atl.dll, registering, not registering, etc. When I'm about to show the report in the app, it dies without errormessage.
I already have all the files installed that Dependency Walker shows, same mdac, but still doesn't work.
I developed the app under XP, but since than I installed the VC 6.0 to a win98 machine as well to check dependencies. Is anybody out there who has something similar working on win98? Might be possible to check file versions...

thanks

Hi, I got through the same problem some time ago and there is the solution. Inno script with Crystal Report Installation.

Crystal Report 9 and 11 Installation - Inno Script

I like Inno since it's fast, easy and you have full control over the whole process. Crystal Report msi package is just pain.

Hope It helps. Thumbs Up | :thumbsup:

Subclassing Control

Hi, I am trying to create a simple control which is a subclass of COMBOBOX. So using MSDE 2003, new C++ MFC project, create control based on COMBOBOX.
How do I expose the combobox's existing functions like AddItem in my subclassed control? Do I have to add same method to both ctrl and interface?

Many thanks for any helpful pointers...
Patrick

What do you mean exactly ? You want that the user of the control will be able to call AddItem (for example) as it was possible to do with the combobox ? If yes, then you don't need to do anything: the class 'inherits' also all functions from the base class.

Yes, that's exactly what I mean. But currently they do not have any methods/properties/events. I can do things like add the OnClick event though, by adding a "stock" event.
If they should be there already then it means I am doing something wrong - I will see if there is anything obvious I am missing.
Thanks.

Datatype Misalignment

I have a Datatype misalignment issue with one of my dll's.
The thing is that all the code inside the dll used to be in a normal .exe application, but since multiple apps will use the functionality inside it we decided to make it a .dll. When the code was completely in the .exe applications everything went very smooth, now however that I made a dll I got this Datatype misalignment issue.

If I do a step by step debug the crash occurs on a line:

m_zsRow = new char[nLen+1];<br />

with m_zsRow being a normal char* declared in the class header.

Does anybody know how this could happen? And how I can fix this?

Thanks for any help you might provide,
Greetings,
Davy

Hello,
Well apparantly all that was needed to find the answer myself was to post the question here Smile | :)

.
The error apparantly was not located in that function, it was a few steps up in the call-stack. There was memory being allocated like:

char* aString = new char(A_Certain_Length);

so with parenthesis in stead of square brackets. How nobody found that out earlier is a wonder to me... Anyways, fixing this fixed the problem. I don't know why this caused the Datatype misalignment error though.

Thanks anyway,
Davy
