While working with "Execl XML toolbox" in C++, I attempt to implement
a logic which is equivalent to the following VB piece of code:
Public objExcelApplication As Excel.Application
Public objWorkBook As Excel.Workbook
Public objWorkSheet As Excel.Worksheet
Public objXmlMap As Excel.XmlMap'
1. list XML maps in the given Book:
.
.
Dim oMapInfo As Excel.XmlMap
For Each oMapInfo In objWorkBook.XmlMaps
msgbox oMapInfo.Name
Next
' 2. Pass back an Excel schema source
dim xSchema As String
xSchema = objXmlMap.Schemas(1).XML'
3. Export The Excel data as XML
dim xData As String
Call objXmlMap.ExportXml(xData)
All necessary standard libraries are #imported into my C++ code / project:
MSO.DLL - contributes MS Office
VBE6EXT.OLB - contributes VB extensions
EXCEL.EXE - for Excel.
However - none of them exposes any helpers, wrappers or any thing else
by which xmlMaps , xmlScemas collections and their associated contained items xmlMap,xmlSchema -
can be accessed easily like other Excel entities.
What did I miss?
Thanks
Hillel.

Hi,
I am trying to get the types of drives (floppy, hard disk, CDROM, etc.) that Directory::GetLogicalDrives() returns. Directory::GetLogicalDrives() returns an array of strings. How do i get this in .NET?

I have a question about the value returned in the fifth parameter (lpulObjType) of the OpenEntry() function.
For reference here is the prototype
HRESULT OpenEntry(
ULONG cbEntryID,
LPENTRYID lpEntryID,
LPCIID lpInterface,
ULONG ulFlags,
ULONG * lpulObjType,
LPUNKNOWN * lppUnk
};According to MSDN[^] "Because the address book provider might return a different interface than the one suggested by the lpInterface parameter, the caller should check the value returned in the lpulObjType parameter to determine that the object type returned is what was expected."
Now that is all fine and good, but does anyone have any idea what the proper return values are for the lpulObjType parameter? How can I check the value if I have nothing to check it against? If I ask for an IMailUser interface how can I be sure, using the lpulObjType value, that the interface I get is an IMailUser interface?

I have never worked with this, but looking at the documentation for IMsgStore::OpenEntry[^], which also has a similar parameter, I'd guess that the object type would be one of the possibilities shown for the PR_OBJECT_TYPE property[^], and that in your particular case the expected type would be MAPI_MAILUSER, which is defined as ((ULONG) 0x00000006) in MAPIDefS.h
Hope that helps,

I want to open a non-existing file, and write to it and read from it without closing and re-opening.
open using CreateFile(). which parameters should be used for this function?
|
|
|
|
|
How about:
HANDLE hFile = CreateFile(..., GENERIC_READ | GENERIC_WRITE, ...);
WriteFile(hFile, ...);
SetFilePointer(hFile, ...);
ReadFile(hFile, ...);
CloseHandle(hFile);

I want to see what kind of connection a computer has. To this end I am using the InternetGetConnectedState function(if you have any better ideas I am all ears).
<br />
<br />
char * tip_de_conexiune(void)<br />
{<br />
char respuns[1024];<br />
<br />
DWORD tip_de_conexiune;<br />
<br />
InternetGetConnectedState(&tip_de_conexiune,0);<br />
<br />
switch(tip_de_conexiune)<br />
{<br />
<br />
case INTERNET_CONNECTION_LAN:<br />
{<br />
strcpy(respuns,"lan"); <br />
MessageBox(0,"lan","lan",MB_OK);<br />
}<br />
break;<br />
<br />
case INTERNET_CONNECTION_MODEM:<br />
{<br />
strcpy(respuns,"dialup");<br />
MessageBox(0,"modem","modem",MB_OK);<br />
}<br />
break;<br />
<br />
case INTERNET_CONNECTION_OFFLINE:<br />
{<br />
strcpy(respuns,"offline");<br />
MessageBox(0,"offline","proxy",MB_OK);<br />
}<br />
break;<br />
<br />
case INTERNET_CONNECTION_CONFIGURED:<br />
{<br />
strcpy(respuns,"configurat");<br />
MessageBox(0,"configured","proxy",MB_OK);<br />
}<br />
break;<br />
<br />
}<br />
MessageBox(0,"a","b",MB_OK);<br />
<br />
return respuns;<br />
}<br />
<br />
this works but it returns none of the predefined values either when I am on or offline. I have a dialup connection.
any other way of doing this?
or what is wrong with this?

Each of those values is a bit flag. The result contains one or more of them. If you use a switch on the result you are checking for each of them but excluding the possibility of combinations.
Try something like this instead:
CString sFlags;
if (tip_de_conexiune & INTERNET_CONNECTION_LAN)
sFlags += "Lan ";
if (tip_de_conexiune & INTERNET_CONNECTION_MODEM)
sFlags += "Modem ";
if (tip_de_conexiune & INTERNET_CONNECTION_OFFLINE)
sFlags += "Offline ";
if (tip_de_conexiune & INTERNET_CONNECTION_CONFIGURED)
sFlags += "Configured ";
AfxMessageBox(sFlags);

thanks man
it works now when I am online
it correctly shows modem configured as in the 2nd and 4th ifs in your code
but when I am offline it shows nothing it does not show offline
why is this man?
and everybody else that might know?

the return value is 0x12 always as I tested.
includeh10
|
|
|
|
|
how did you test includeh10?
|
|
|
|
|
UINT uValue=InternetGetConnectedState();
CString cs;
cs.Format("0x%X, %d",uValue,uValue);
MessageBox("Hello",cs,MB_OK);

I use broadband at home.

Hi!
How do I calculate the value of dwBloblen of pbKeyBlob read from a file.Even if i use the number of byted read returned from the CFile read function the key import function fail.How does the know the receiving side know the size of KEYBLOB.
////read KEYBLOB from a received file
CFile file;
BYTE *pbKeyBlob1 = NULL;
DWORD dwBlobLen1=512; //just for testing but doesnt work for RSA
//signature
pbKeyBlob1 = (BYTE*)malloc(dwBlobLen1);
// Read the key BLOB from the file.
if(file.Open("key.txt",CFile::modeRead))
{
file.Read(pbKeyBlob1,dwBlobLen1);
file.Close();
}
// call CryptImportKey
if(CryptImportKey(
hProv,
pbKeyBlob1,
dwBlobLen1,
0,
0,
&hPubKey))
{
MessageBox("The key has been imported");
}
else
{
MessageBox("The key import failed");
}

Have some legacy code generator (EZbuilder) which reqires Visual v 1.52. Where can I get a copy?
|
|

It's difficult to get 6.0 let alone 1.52. I reccommend you port your code to a current compiler.

Ver. 1.52 was the last version of the Win 3.1 (16-bit compiler). It was include with the release of VC Ver. 4.0.
You need to bring the code upto date.
It's not that difficult, just time consuming.
The MSDN covers the subject of updating 16-bit programs to 32-bit, some where.

It is possible that the code runs under a DOS enviornment, so a newer compiler will not help. Does MSDN still provide the legacy archive?

With a name like EZBuilder, it probably wasn't DOS. If it was then it should have been written according to the standard, in which case it should still compile as a console application. The only problem you may run into under that is modern system security for hardware access.
If it was written for DOS, then the whole interface needs to be rewritten anyway.
Steve Mayfield wrote:

Many of the examples (and samples) you see in MSDN are written in C, there's your legacy archive. Most of the code I wrote years ago for DOS still compiles and works today (still supported).
Note: Many of the examples are the same ones that where in the help file for both Ver. 1.0 and 1.52 of the compiler.
If you seperated most of the code that does the work from the interface code that shows it to the user, then you should still be able to use that same code.
The conversion requires: you to handle some messages differently and some functions are no longer supported.

I seem to recall seeing a C++ instructional book that came with v1.52 on a CD, that might be the easiest way if you can't find a release online.

I'm trying to use MSXML 4 DOM to parse a xml document in Visual C++, but without success. A snippet of the xml structure is a following:
<code>
<data>
<album label="Album title 1">
<track label="Label 1" sndUrl="1\0.jk" txtUrl="1\0.jk"/>
<track label="Label 2" sndUrl="1\1.jk" txtUrl="1\0.jk"/>
</album>
<album label="Album title 2">
<track label="Label 1" sndUrl="2\0.jk" txtUrl="2\0.jk"/>
<track label="Label 2" sndUrl="2\1.jk" txtUrl="2\0.jk"/>
</album>
</data>
</code>
Can anyone give me a code snippet to parse album label, track label, sndUrl, txtUrl attributes to a CString?
Please help!
Thanks in advance for any answers.

What is the problem ? You don't know what to start from ? Or you can not look at MSDN, where MSXML interfaces are well documented ? Or you have some kind of errors ?
If you have you own code, which is not working, you can post a fragment.
