Multiple Tables in a Dataset from multiple XML Files?

Hi,

I'm using vb.net and a Windows CE.net device. I have three xml Files that I want to read into a single Dataset so that I can use a dataRelation. The copy method used to a copy a table doesn't seem to be supported in the compact framework. Mad | :mad:

Any ideas how you do this?

I'm trying to use the dataset.readxml method to get the tables into three datasets and then combine the tables into one dataset.

Any help would be greatly appreciated.

This is quite old but I landed here as I was looking for something related.
using ReadXML works only with one file at a time; Once the first file is read the subsequent once wont be read. It creates one dataset with one table.
Alternative way would be to create a dataset for each of the xml files then merge the datasets.
There seems to be a way of creating the dataset from the xsd file and thus retain relationships and constraints. I am looking out for that badly!

Screen Rotation

Hi,

I have an Intermec 700C device running PPC2003 1ST EDITION and I'm looking
for a way to to change the screen orientation programmatically. I have
already tried the API "ChangeDisplaySettingsEx" function but it didn't work.

I know that the Second Edition supports this, but the manufacturer says that
upgrading to the Second Edition the existing devices that my client already uses is
not possible. Therefore the OS has to remain PPC 2003 1st Edition.

After some investigation, it seems that the only way to do this is by
creating a display driver that supports screen rotation using a tool by
Microsoft called the "Platform Builder" which is usually supplied to device manufacturers.

Unfortunately, this is not included with my MSDN Subscription, so my
question is if anybody knows where can I find a display driver that
supports screen rotation with PocketPC 2003 First Edition?

I also know that there is a utility to do this but the customer requires
that I do it from within the application(that is programmatically).

TIA

Has anyone had success in overriding CompareItem in a ListBox-derived class, in a PocketPC MFC app? I've tried lots of variations but CompareItem never gets called. (in a EVC 4/C++ project). Any ideas?

set focus to next edit box

I am new to windows and C++ programming. I am developing an evc++ 4.0 application for a handheld
computer running CE .NET 4.2. I have a dialog with many edit box controls. How do I change focus to
the next control in the tab order when the user enters the max number of characters allowed for the
current control. (I have defined the max number of characters by creating member variables via the
ClassWizard.). Do I have to check for an EN_CHANGE message and then check the length and then call
NextDlgCtrl or is there an easier way? Thanks in advance for any assistance.

Yes, that's the way to go. I'm afraid there's no easier way.

One more question. Is it more efficient to use UpdateData() and CString method GetLength() to determine length of the member variable OR to use GetDlgItemText()?

Dear all,

I'm having problem displaying mixture of chinese and english character in multibyte format on a dialog box.

If I have a char array like this:
char szText[18];
szText[0] = 0xa7;//first chinese character
szText[1] = 0x41;//first chinese character
szText[2] = 0xa6;//second chinese character
szText[3] = 0x6e;//second chinese character
szText[4] = 0x20;//the rest are single byte english character
szText[5] = 0x48;
szText[6] = 0x6f;
szText[7] = 0x77;
szText[8] = 0x20;
szText[9] = 0x61;
szText[10] = 0x72;
szText[11] = 0x65;
szText[12] = 0x20;
szText[13] = 0x79;
szText[14] = 0x6f;
szText[15] = 0x75;
szText[16] = 0x3f;
szText[17] = 0x00;

How do I convert them to a CString type and display on the dialog box.
I have tried to use MultiByteToWideChar() function but was unsuccessful Confused | :confused:

.
Pls help and advise. Thank you.

Hi All,

I am currently developing software for a Windows CE PC which i currently
dont have the hardware, thus I am using the emulator for VS2003. The
software writes out Timesheet entries to file on the WIndows CE PC which
I have done but I require to get the files off the emulator to confirm
the are correct.

Is this possible with the Emulator or would I need the hardware for that?

Best Wishes

Simple EVC4.0 app to run a CAB

To create a simple app in EVC4.0 to run another .exe, I would simply use the "CreateProcess" command!

This, however will not run a CAB file...

Can someone tell me how I can do this ??? Please.... Cry | :((

you can run cab files through the WCELoad.exe app in the windows folder

<br />
CreateProcess( L"\\Windows\\WCELoad.exe", cmdParam, NULL, NULL, NULL, CREATE_NEW_CONSOLE, NULL, NULL, NULL, &pProcInfo );<br />

where cmdParam is the full path of the cab file... you can also put some extra parameters in the cmdParam, but I don^t know them all...

Strange! I don't understand why I can't get it to work.. I setup the "CreateProcess" just as you have above, and included the full path to the cab! The new app compiles and downloads to the device without error, but will not run !!!!

Any Ideas ?? Frown | :(

Ok, This is how I run the cab files programmatically:

<br />
PROCESS_INFORMATION pProcInfo;<br />
<br />
WCHAR cmdPara[256] = L"/noaskdest /delete 1 ";<br />
//underneath FileName is the full path + filename of the cab file.<br />
//eg FileName: "\FlashDisk\TheInstallFile.cab"<br />
wcscat( cmdPara, FileName );<br />
<br />
return CreateProcess( L"\\Windows\\WCELoad.exe", cmdPara, NULL, NULL, NULL, CREATE_NEW_CONSOLE, NULL, NULL, NULL, &pProcInfo );<br />

Hope this helps you... Maybe it was the missing parameters that failed to make it work for you...
This should give some info about params you can pass in the cmdPara:
WCELoad info[^]

Davy

Hi there,
May I ask a question?
I wanna write a program about Call Logs.
However, when researching the information about Call Logs in MSDN, It's not enough to understand for me...
Would you please supply me any simple sample about Call Logs?
Thank you very much.

What do you want to do exactly ?? And what do you mean by call Logs ?
Try to be more precise because it is difficult to guess what you are trying to do.
