I want to create an Access database on my PocketPC (WinCE4.2, PocketPC 2003 OS). Then using C# to populate tables, query tables, ...
From a simple search on Google.com I find that I must use ADOCE.NET but I didn't succeed to download it and also didn't see any control that I can use from Visual Studio 2003 (I created a project for Smart Mobile Device).
Is there any one has experiences doing such kind of work?
Best regards,
A. Riazi

Hi,
Here's the problem. We have an XP Embedded box that is mobile and goes in and out of Wireless (Cisco) coverage. Occasionally the box will roam from one Access Point to another and sometimes this causes a "LEAP Authentication" problem. That is, a bunch of dialog boxes pop up and the user has to click "OK" and re-enter their network password.
Now I've successfully implemented a Windows Service in C# that will call FindWindow() and SendDlgItemMessage() etc to do all the work; testing on my laptop while I'm logged on has made me a happy camper. Note that it is very similar to the article here:
Using P/Invoke to Automate Database Signon
The biggest problem is that the series of dialog boxes that pop up can pop up while Windows does not have a user logged in. That is, the logon prompt is showing with these Cisco dialog boxes patiently waiting for user input. My service runs while this is happening, but it never ever sees these dialog boxes. And I even have the service set to "Interact with Desktop".
Has anyone had any luck with a similar problem? Do I have to do more than "FindWindow()". Is this a service setting?
I apologize if this isn't the correct forum for these problems.
Thank you for your time!
-Chris

For those of you who are interrested, I just started my blog (yes, even me!). It's about my experience with Whidbey Beta 2 (and up). We just started using it internally and I'd like to share my problems, workarounds, thoughts, tips, tricks and so on with the world.
If you feel like it, come and see http://whidbeybeta.blogspot.com/[^]
I will use this mainly as a log of the bugs and problems I experienced and how I managed to fix them.

I have a problem with setting the datasource property of a datagrid in the compact framework 1.0.
Here's the senario:
I'm making an asyncronous web service call that returns a dataset with one table. This could be any data in the table. From within the thread for the web service call, I want to get the data and then set the datasource property of the datagrid to ds1.Tables[0];. When reaching that line of code the entire application hangs. I have to stop debugging to return to normal state. Now I at first thought this was a problem with my coding, but the more I delve into it I find that it seems to be a threading problem in the framework. I do not have this problem with any other control, be it a listview, combobox... I can set their display member property while in the other thread with no problem. Now I can change the web service call syncronous and it works fine. The problem seems to center around the thread issue. Has anyone seen this before on a datagrid? Also this problem is inherited by ComponentOne's mobile datagrid since it does the same thing. I have tried converting the dataset to an arraylist and loading it that way... no juice... I have tried creating another dataset at intialization and creating a dumby table with the same charitoristic as the one coming from the web service. set the datasource property of the datagrid to the table, then in the asycronous web service call actually use the dataset.ImportRow in a foreach statement from the dataset the webservice call returns and it will hang on the first record. I guess because the secondary thread is trying to change the datagrid...
Any suggestions?

I'm looking for a way using C# or VB.net to reference variables. More specificly, I have a loaded hashtable that was created on my main form. When I open a new form, I need to have access to that information in the hastable. I don't want to pass the table between forms as this would create copies of the original and end up using more memory.
What is the best way to accomplish this??
|
|

|

No it wont take up much memory! If you pass your HashTable to another form only a reference to that single HashTable is passed. So the memory usage is just 4 byte (on a 32 bit os). This also means changing the HashTable in one place also changes it everywhere else you passed the reference to.
If you still dont want to pass the HashTable around and you only need one instance of it in your whole application declare the variable in your main form public static. This way everyone can access it with MyMainFormClassName.MyPublicHashTableVariable.

Except for value types, everything in .NET is an object (and even value types can be boxed to be objects). All objects are already passed as references. That's why you don't need pointers, or * to dereference a pointer, and that's why you don't need new and delete--the GC keeps track of the references to an object.

Hi,
I would like to know if there is any way to perform a deserialization from a binary file that has not been serialized first.
Actually, I've got a binary file produced by a VC++ app using some structure dumping. I have all the code and the structure of the file and I now need to get it in a C# .NET app.
I naively wanted to recreate the structure dumped in the file as struct/classes in c# and read the data into them.
Thanks in advance for the help

You can always create your own C# class that has the same structure as the C++ class. You can then use a Stream to read data from the binary file byte by byte and fill in your class variables.

Senthil

Thanks for your reply
Actually that's exactly what I wanted to avoid, the byte to byte reading of my file.
There should be an more elegant and maintenable way to read structured data from my file.

as in where's the IL asm code, etc.

I need a "toolbar"-like control (for my "Windows.Form"-based Document Viewer application) with functionality similar to modern ("Microsoft Office", etc.) products:
I want to have an ability to represent it floating over, or docked to the top of the main window; to have entry fields on it (like "Page: # of #" for quick navigation), etc.
Apparently, straight use of "System.Windows.Forms.ToolBar" class (provided by framework) doesn't give such a rich functionality.
I'm quite a novice in .Net GUI development and I did not find anything about it in MSDN (maybe I just made wrong search 
I'm sure it's a very common task nowdays, so there should be some well-known solutions (or approaches) for this problem!
Could somebody post an example, reference, or link to discussion about those matters.
Regards,
Andrey

This will be available with Whidbey, but there are also a couple examples here at CP for v1.1.

I'm currently writing an application that uses LogonUser function from advapi32.dll (Detailed here). The only problem is that I also have a pass a logon provider constant to the API. The technique I was using was to call the procedure four times - once for each of the 4 types of logon providers (NT3.51, NT4, NT5, and Default). While this works great if the username and password are correct, if they're not, it equals 4 failed logon attempts, which locks the user account. I would just use LOGON_DEFAULT, but I was unable to get a positive authentication from a W2K client on an NT4 domain.
Do here's my question: Is there some way that I can determine the logon provider from another API call or somewhere in the .NET framework? That way, I would only have to call the API once, using the correct provider constant, to be able to determine if the username/password/domain combination I've collected is valid. Again, DEFAULT appears not to work in certain situations (like an NT5 or higher client against an NT4 domain) - maybe there's something else about DEFAULT that I'm missing. Any ideas?

Greetings all.
I'm trying to meassure the contents of a string in a webapplication, and have problem with the GetTextExtentPoint32 function and how it works. (I'm using VB.NET cause that is what we have to program in at work, so eventhough this is more for my own benefit and interest, I'll still use VB)
I've never used this API before, so please have some compasion for my newbie questions
Most of this information has been put together using msdn and a few webpages (I lack some decent code exampels in VB which I can read from)
So far what I've done is declaring a number of functions, amongst others:
Declare Function GetDesktopWindow Lib "user32" () As Long
Declare Function GetWindowDC Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function GetTextExtentPoint32 Lib "gdi32" Alias "GetTextExtentPoint32A" _
(ByVal hDC As Long, ByVal lpsz As String, ByVal cbString As Long, ByRef lpSize As SIZE) As Long
I've created a stucture:
Private Structure SIZE
Dim cx As Long
Dim cy As Long
End Structure
Then in my function I do this:
Dim sz As Size
Dim strTestString As String = ""ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz""
Dim hDc as long = GetWindowDC(GetDesktopWindow)
Dim hFont = GetStockObject(ANSI_VAR_FONT)
dim hFontOld = SelectObject(hDc, hFont&)
As far as I understand hDc is the handler to the "screen-area" used for drawing.
I'm by far not sure what hFont of hFontOld does (ANSI_VAR_FONT = 12), but font-buisness is a good guess I hope 
(Taken from websites, not my own)
I then call:
GetTextExtentPoint32(hDc, strTestString , 52, sz)
52 I guess is the number of characters in the string. (String and 52 is taken from websites, and not my own)
And then I get a NullReference exception when running the code (and here I'm stuck).....
Does anybody have any information which can guide me further, or have some good code exampels I can use/read?
I'd really like to this work, seeing as if it does I could perhaps implement it at work, but also because it is starting to nag at me, and I hate having to leave it unfinished.
Please help if possible
With regards and hopefullness
