I want to get a file name back from the saveFileDialog box and store it as a global variable. What Type should I declare this varialbe as? Seems like the return type for the saveFileDialog file name is String and the compliler is not liking this Type..

Anyone have a simple VC++ .NET example on how to get the user selected file name back from the saveFileDialog box and stored in a variable?

Thanks.

Here's what I have used:

CString strFile;
CFileDialog fSave(parameters);
if ( fSave.DoModal() == IDOK )
{
     strFile = fSave.GetFileName();
}

For whatever reason, my .NET compiler is not liking the declaration of a variable as CString Type. I wonder if there needs to be included another .h file to be able to use String type?

Compiler does not like this:
CString myFileName;

I figured out what I was doing wrong.

I did not realize that the return type of the file name is a pointer, so it needs to be declated like this.

String *myFileName;

I understand what this does, but I was wondering how people felt about it.

Is it better to have incremental linking on or off?

and

Do you, personally, prefer to have incremental linking on or off?

I have "Incremental linking" on, and "Edit and Continue" off by choice.

Link times are notably smaller (and the only glitch that happens is finding a function that no longer exists). E&C is for veebees.

XML parse to get a single node

LCI21-Jul-05 3:44

Why is it that when an XML file is has a root node that looks like this:

-(Test xmlns="urn:response"\)
(MyTest)test data(MyTest)

I can't seem to select singlenode on //Test//MyTest to get the text. But if the 'xmlns="urn:response' is removed to look like:

-(Test\)
(MyTest)test data(MyTest)

then i can selectsinglenode and get the text.

How would i read an xml file with root having a namespace definition??

Please Help

I do not understand.

When i define my tag it is like this

_bstr_t mybstrtagTestText = ("//Test//MyTest");

The above does not work when i do a

MSXML2::IXMLDOMDocument2Ptr pDocument;
MSXML2::IXMLDOMElementPtr pDocRoot;
MSXML2::IXMLDOMNodePtr pTag;

pDocRoot= pDocument->documentElement;
pTag = pDocRoot->selectSingleNode(mybstrtagTestText);

This is because the XML file that i am reading has has a root that looks like
(Test xmlns="urn:response") - I can't change this part

what should i do differently in my code?

Promlem is in XML
This is invalid XML

<Test xmlns="urn:response"/>
<MyTest>test data</MyTest>

XML document mast have one root node in first case you have two
Test and MyTest

This is valid XML
<Test xmlns="urn:response">
<MyTest>test data</MyTest>
</Test>

I am using threads and when I compile, it says I have to include /clr in the command line. I added in the managed extension option and saw that /clr had been added. Now, I get the error that says /RTC and /clr cannot both be in the command line. I can not seem to get rid of /RTC. I have tried to use this: #pragma runtime_checks( "", off ) --but it doesn't seem to do anything. Can anyone help me?

Hello

But what types are using for decimal addition ?

int a = 0x12;<br />
int b = 0x56;<br />
int c = a + b;<br />

Does it what you need ? So, you can use any numeric type.

hex is a way to represent values. If you work with integers then you can do:

int a = 0x0a;
for (int i = 0; i < 10 ; i++)
a += 0x08;

Can I get a handle to the root of logical drive?

Hi
I am interested to get a handle to the directory that consists the root of a logical drive. E.g. I want a handle on C:\ I noticed that FileFirstFile will refuse to give me back such handle. Also do time attributes (i.e. creation, modification, last access) have any meaning for the root directory? They certainly have meaning for the subdirectories but what about the root.

Thanks for any given help

The GetFileAttributesEx function retrieves attributes for the specified file or directory. Probably what you want to know.

what do you call "caption bar" ? an edit box ? or the title bar ?

the title bar cannot get the focus, never.

if you want to set the focus into a specific control on the dialog, do this :

(GetDlgItem(IDC_MY_CONTROL))->SetFocus();

How do I Set the TAB Order of Dialog Controls through Code in MFC VC6?

I am trying to set the TAB order through Code. It’s not enough setting the Tab Order initially using Layout - > Tab Order. As the TAB order needs to be set to a different order during run time. How can I do this exactly?

Any help will be greatly appreciated.

Use SetWindowPos() to change the Z-order.
