Call Unmanaged Mobile CE Dll From Full .Net Framework (Run On Desktop)
Jul 15, 2010
I have an Unmanaged Lib compiled for Windows Ce. I am trying to call this dll from VB.net Full Framework .Net 4 Client Profile Windows application. I am trying to use the same code that I use in the Compact Framework application. It compiles without errors and runs but when Invoking a function I get error ex = {"An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)"} Is it possible to use the Mobile Unmanaged Dll on the Desktop ? Here is the Wrapper code I use to call the Dll:
Imports System
Imports System.Runtime.InteropServices
Module modM300CF

I am calling a function from a VB.NET webserver to a custom written unmanaged DLL.If we call this DLL via a webservice on a multi-core server we run into problems and it always crashes.If I reboot the server and make it only use a single-core, it always runs fine and never crashes.I know the DLL call is responsible for the crash as I have outputted debugging code just before and after the DLL call.I can force the processor affinity of the .NET code to 1 core but this doesn't apply to the unmanaged DLL.How can I force the unmanaged DLL to only run on a single core as I am sure this will solve the problem?

Just finishing off an update to an application written in VB.NET that used to run fine under CE.NET 4.2. Deployment platform is now Windows Mobile 6.1. The application runs in full screen, however whenever a new form is opened, the task bar, i.e. the bar with the start button comes to the fore and then the new form takes over. This is particularly annoying as I have a form that has many sub forms which are 128,128 and still the task bar flashes and obscures part of the user input screen

My app is built in vb.net compact. All these years in all versions when user taps at the top or bottom of the screen (depending on where the task bar is located) it brings up the task bar and start menu fine. But now the latest OS build doesn't do it anymore. I'm thinking of having a button in my app to bring up the task bar but not sure how to do it.However, in IE full screen there is a circular button that brings up the task bar. If I can accomplish it in my app that would be good.

i would like to build an inventory manager application that would have two versions :1. Would run on the desktop 2. Would run on windows mobile 6 I would like to have both these versions store and read data from a database that can be stored centrally either on a webserver or somewhere on the LAN.
I would like to know can i use Access as my backend database or sql server ? will windows mobile app be able to access it and read and write to it Note : I would prefer to create only one database that will just store the details in the tables and do not need any other functionality. All functions such as save,edit,delete,search,filter etc with be done from the FRONT-END VB.NET interface ONLY If you suggestion involves the use of 2 databases such as one for desktop version and one for windows mobile then please also tell me how would i sync the data between them.

I am writing my first windows ce app. I am using an xml file (app.Config) to store state data... basically user preferences on the last location (connection string) that the person was using before closing the app. I am having trouble understanding what is happening on deploy. It looks like it is copying my xml file to the debug folder on deploy. My problem is, when I save the xml file it is not saving in my project. Is there another folder in which the emulator resides that contains all of the state data and possibly the file that I am writing out? I am saving the doc to the same filepath as I am reading in but it does not actually save or throw error or anything.

I have 2 applications that needs to talk to each others. After some research, I wanted to go with managed pipe (namespace system.io.pipes). The problem is, the client must send commands to the server but need to also wait for incoming message from the server at the same time. I tried to go asynchrone but it doesn't work.

I have an application that is written in VB.NET, using the System.Windows.Forms.Form as the front-end GUI. It runs perfectly on my Windows machine however recently there is a business requirement to convert this application to run as a web application so that people could view them in their blackberries when they go to the URL. Is there any quick way to perform such a conversion or I will have to translate the code line-by-line for such cases?

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?

I have a desktop application which reads files from a specified folder, then deposits the files to a folder in a third party document management system based on criteria that the user provides.
is it possible to somehow provide different parameters to the code, depending on which shortcut of the application the user clicked on to start it up?

I'm working in VB.Net and I'm trying to make a piece of code more generic.In fact, there's a big Select Case statement that build a ProxyServer based on a value passed in parameter (a string).
Select Case _strNteraHL7
Case Constantes.NomPRPMIN306010
strUrl = ObtenirUrl("ProviderDetailsQuery", _strVersion, _strEnvir, True, _blnSimulCAIS, _blnSimulPDS, _blnSimulPDSSIIR, _blnSimulPDSInteg)
[code]....
or something similar, so I can remove all those big switch cases, that repeat the same thing 30 times.objWsHL7 being an object or type "object" at compiling.Again, in another switch case statement,
objMsgHL7Out = _objWsHL7.ProviderDetailsQuery(_objMsgIn)
objMsgHL7Out is a System.ServiceModel.Channels.Message
_objMsgIn is a System.ServiceModel.Channels.Message
_objWsHL7 is an Object

I have written my own function, which in C would be declared like this, using standard Win32 calling conventions:int Thing( char * command, char * buffer, int * BufSize);I have the following amount of VB figured out, which should import the dll and call this function, wrapping it up to make it easy to call Thing("CommandHere",GetDataBackHere).UPDATE:This code is now a working solution, as shown here:
Imports Microsoft.VisualBasic
Imports System.Runtime.InteropServices
Imports System
Imports System.Text
[Code]...
Updates: I got the code to build by following the help received here, and then I had forgot the As Return Type (which got me a MarshalDirectiveException PInvokeRestriction). Then I had an assertion failure inside my DLL, which lead to an SEHException. Once fixed, this works BEAUTIFULLY. There are newsgroups where people are saying this can not be done, that VB only loads managed dll assemblies (which I guess is the normal thing most VB users are used to).

I'm planning on using the Smart Device Framework 2.3 to use the signature control panel in a Windows Mobile 5 application using the compact framework 3.5.
The control has the option to save the signature as either a byte array of points, or as a bitmap. Now seeing as I want to store the signature in a sql compact database, I guess the byte array is going to be better. The trouble is, I'm not sure how to render that in a full WinForms application after I've transferred it back to the desktop.
I need to show the signature on a report, so it would need to be an image I could link/embed into the report.

Its based around space invaders and works quite well. however because i have finished my college project almost 2 weeks ahead of the assignments release date, my tutor has asked me to tweak my project and make it better.So far i have added a full main menu to the game and a full splash screen. I would like to add in a section for recorded high scores but have no idea how to attempt this at all.

Some of u already know I'm making a 'virtual desktop'- thing.Only one problem. When switching to a new desktop it starts a new instance of my app in that desktop (works) and on the form load event it says process.start("explorer.exe") <- here is the problem. It only shows a window not the actually bar.Also this may be important it shows the window, but when I navigate to explorer.exe 'C:Windowsexplorer.exe' and open it there. The explorer bar does show up.
