Anyone knows any good way to do that? I have a (raw-formatted) XML file and I need to build ADO recordset from it. The last resort would be parse the XML file and build the recordset from scratch Dead | X|

Hope there is a way to use the XML file as data source.
Thank you.

Unfortunately no, there is no such thing, unless you use ADO.NET

There is quite a bunch of Xml readers here in the SOAP XML section, I guess it shouldn't be that hard to reuse one of them, especially if the Xml content is simple (no deep use of namespaces, etc.).

I know ADO has a way to write out a recordset as XML. One would think it could read in an XML dataset as long as it conformed to some schema structure.

If you want to load the recordset to insert this data into a database, then you could consider transforming (XSLT) the XML to generate a file, that will be in the correct format for sqlloader or BCP. Lesser XMLDoc parsing code inside your application then.

I am trying to restore a registry key by using the RegRestoreKey. I keep getting an ERROR_ACCESS_DENIED (return value 5) from the function.

I have ensured that I have the SE_RESTORE_PRIVILEGE.

Here is my code. Any help would be appreciated.

<br />
<br />
// This function is directly from MSDN website<br />

Look over Microsoft's specification of RegRestoreKey(). Maybe you left something out.

Passing macro's via NMAKE & handling (Q237870)

Editted: for better understanding, I suggest one read the MSDN-Q237870 before continue

Hello all,

We've here automated build-scripts (Batch files and also 4NT batch-files) that creates user environment at a central (build)server. One of the scripts also executes NMAKE <makefile> in order to build the application.

Problem:
Within the scipts I've the variable MAJOR_VER, MINOR_VER and BUILD_NR. I would like to pass these with NMAKE in such way that I can use those variables (Macro's) to fill in the VERSIONINFO-resource: the file + product version entires. This structure is already moved to .RC2-file so its in our control.

When manually define them in a header-file and include this in RC2-file (as mentioned in MSDN: Q237870) this works.

But...
I want to pass this info via batch-file (NMAKE), iso calling a script which modifies a headerfile. Anyone suggestions?

Thanks in advance,

EiSl

This is somewhat of a problem as I can't compile my programs anymore Cry | :((

Now, my biggest problem is that my Visual C++ cd is in Europe and I'm in the Carribean at this moment.
You might say: hey, what's the problem, go and enjoy the beach and the sun and forget about programming Wink | ;)

but I should really appreciate it if someone can send me a zip file with the contents of C:\Program Files\Microsoft Visual Studio\VC98\MFC\LIB (with mfc42d.lib, ...) to wjans@aqualectra.an?

hi
i have a "char* printername" variable is there. in this variable i want to store the selected printername. i assign this value to "dmDeviceName" structure member of DEVMODE structure. it's giving data type conversion error.
dmDeviceName datatype is TCHAR or BCHAR.
how can i assign my value to that. please help it's very urgent.
thank you

Instead of using char* I would recommend using CString if you are using MFC or WTL. If not then use std::string to store the name of the printer.

Third option would be to use a TCHAR printername[ 256 ]; to store the name of the printer. Then when you want to store it use _tcsncpy( ) to copy the name of the printer from dmDeviceName to this buffer.

But I would recommend using a string class - either CString or std::string.

you can't AFAIK.
Btw, the proper sequence for closing a TCP connection is:

Finish sending data.
Call shutdown() with the how parameter set to 1.
Loop on recv() until it returns 0.
Call closesocket().

How to move a CTreeCtrl item?

Daniel Strigl31-Oct-02 1:50

31-Oct-02 1:50

How can I move a CTreeCtrl item to a other position?

Item 1
  SubItem 11
  SubItem 12
  SubItem 13
Item 2
  SubItem 21
  SubItem 22
  SubItem 23

So I want to move Item 2 with all subitems (up or down):

Item 2
  SubItem 21
  SubItem 22
  SubItem 23
Item 1
  SubItem 11
  SubItem 12
  SubItem 13

How can I make this? (I want to move the current selected item with all subitems up or down)

There's no built in method that does this. The only way I'm aware of is to manually walk the tree, create new items with the same attributes as the old ones and finally delete the old ones. It would probably be a good idea to disable redrawing in the control while doing this ( m_wndTreeCtrl.SetRedraw( FALSE ); at the beginning and m_wndTreeCtrl.SetRedraw( TRUE ); when everything is finished.

CMultiDocTemplate?

Do I need to use CMultiDocTemplate in CApp::InitInstance? Is that what I should read about or do I risk learning something for nothing? Wink | ;)

Re: different CView derived views on same document

Roger Allen1-Nov-02 6:27

Yes, you need to use an addtional CMultiDocTemplate object:

pDocTemplate = new CMultiDocTemplate(
    IDR_PGPCONTYPE,
    RUNTIME_CLASS(CSGAControlDoc),
    RUNTIME_CLASS(CChildFrame), // custom MDI child frame
    RUNTIME_CLASS(CYourScrollView));
AddDocTemplate(pDocTemplate);
pDocTemplate = new CMultiDocTemplate(
    IDR_PGPCONTYPE,
    RUNTIME_CLASS(CSGAControlDoc),
    RUNTIME_CLASS(CChildFrame), // custom MDI child frame
    RUNTIME_CLASS(CYourListView));
AddDocTemplate(pDocTemplate);

By default this will register 2 view types wit hteh same document. When you create the document you will be asked which type of view you want. To add the other view type, you will have to write a function thats adds the new view to the existing document. I did this a while back, but the code has since gone obselete in my app and has been deleted, so I don;t have any example code ready to hand.
