Hi,
I'm trying to read the content of a file which I've put in bin\debug.
So I define StreamReader sr=new StreamReader("file.csv"); but I get this error "Could not find file '\file.csv'".Do you know what the problem is?Why is adding a backslash?
Thanks
P.S. I've put the same question in web development by mistake because I'm trying to do a mobile app

As far as I know WinCE has no concept of a working folder, so all paths are absolute.
This means "file.csv" is the same as saying "\file.csv". You need to set the full path, ex: "yourlocation\bin\debug\file.csv".

|
|
|
You could easily use My.Computer.FileSystem.CurrentDirectory & "\file.csv" or however you call the "Current Directory" in C#/C++.

Hello everyone,
I have used Visual Studio 2005 to create a C# .Net Compact Framework 1.0 application on Pocket Pc 2003 device. But when building the application, there are some errors dealing with System.Data can not find.
I have solved this issue by manually add System.Data from References of project, and it is working now. I am wondering whether we should manually add reference to System.Data in an application based on .Net Compact Framework 1.0 (Pocket PC 2003).
thanks in advance,
George

Hi, i'm very newbie about mobile web application. So i have some problems about deloying a mobile web application in reallife.
I am using vb.net (2003) to make a mobile web application. And i use Nokia web browser 4.0, nokia mobile internet toolkit 4.1, nokia wap gateway 4.0 to deloy that application on local computer and it is running well.
But i don't know how to deloy it in reallife like :
+ Where should i put Nokia mobile internet toolkit on my phone ( client ) or on server?
+ What will i config? ( port, ip ... or something else ).
And one more thing, when i want to move from pageA.aspx to pageB.aspx, i use RedirectToMobilePage("pageB.aspx"). But before moving to pageB.aspx, it ask me to confirm moving. How could i do to turn off that confirmation?
Please give me some advice. Any ideas will be welcomed.

hi everybody,
got a problem on developing with vstudio2003 for my mobile device which is an anubis typhoon 4500sd.
i wrote a small and simple helloworld application with one button on a form that shows a simple messagebox. Everything works fine under the pocketPC 2003- emulator.
but when i build a cab- file (target- device: ARMV4) ,copy it to my SD- Card and install this on my device, the application doesn't start. the installation- procedure seems to work well, no error- messages, but when it's finished and i click the installed icon, nothing happens.
the manual says that the compact- framework is already installed on this device (in ROM), but even when i try to install it again by copying and installing the necessary files to the device (netcf.all.wce4.armv4.cab) the behavior of the helloworld-app won't change. so, the situation today is that none of the vstudio2003- apps that i have build and deployed as cab-file to my device, works.
i have no idea of what might be wrong, perhaps anyone of you ?
with kind regards
heb

I have a form that initially did not have a sip or menu.
Form works fine but needed to add sip for easier editing of user fields.
When sip/menu added, the paint event only fires on the first entry into the form and not subsequent entries.
Paint event would always fire on all loads of the form before menu/sip added.
No additional code added outside of what was added by the designer when sip/menu added.
I've tried refresh and invaliding different components on the form the paint event does not get to the form.
 Any suggestions would be greatly appreciated.

Hello everyone,
In my understanding, Windows OS for device is divided into two sub-categories, Windows Mobile and Window Embedded. And in Window Mobile, there are two sub-categories, Window Mobile Pocket PC Edition and Windows Mobile Smart Phone Edition.
Is my understanding correct?
I have a further question, what is the common points and differences between Windows Mobile Pocket PC Edition and Windows Mobile Smart Phone Edition?
thanks in advance,
George

Thanks Steve! I have read through the article, but it does not cover the various types of Windows Mobile platform -- common points and different points between different types of them.

 I'm using C# to develop an application for an ARM handheld that uses PocketPC 2003. Part of the time I work on an XP machine at home, and part of the time on a Win2K SR4 machine at work. The application runs under the .NET Compact Framework 2.0. It includes a set of Windows forms for data entry. The application looks fine in the VS design view on the XP machine and deploys properly to the handheld. However, when I tried to open the project's design view under Visual Studio 2005 Professional on the W2K machine at work, I received an error message stating that an input string was improperly formatted and the form did not load. I found a reference to what appeared to be an identical error in Microsoft's Knowledge Base[^]. However, the error persisted even after I downloaded and installed the hotfix developed to fix the error. I'm wondering whether anyone else has encountered this problem, and if so, whether they might have found a workaround.
Incidentally, I can build and deploy the solution from my Win2K machine and it runs properly, either under the PocketPC 2003 emulator or on the handheld itself. I just can't make any changes in the design editor on the Win2K machine because the design editor won't load. This problem occurs even if I create a new smart device project in either C# or VB, so it's not just this specific project. It doesn't occur if I create a smart device project in VC++, however. I've repaired VS 2005 through the Add/Remove Programs utility, to no avail. I'm afraid the answer might be a complete re-install of VS 2005 but I dread doing that. I'd be grateful for any ideas or suggestions.

Hello,
I'm trying to use the macro feature of eVC4.0 to add the capability of updating the build number every time my project is compiled/built (there is no built in capability for doing this). So I hunted down so information on how others had got 'er done. All the information I could find was for doing it with the normal Visual Studio (probably the problem). But I've come to the conclusion that my problem is that the VBscript events don't seem to be triggering the handler that I'm defining. i.e. the following code should open a message box when I built the project and it does not!
<br />
'------------------------------------------------------------------------------<br />
'FILE DESCRIPTION: Updates the build number every time a [successful] build happens. <br />
'------------------------------------------------------------------------------<br />
<br />
Sub Application_BeforeBuildStart()<br />
<br />
msgbox "Hey hey!!!"<br />
<br />
End Sub<br />
Can anyone tell me why these VBscript events are not firing within eMbedded Visual C++? There is very little documentation on this. There is one topic that is called "Handling Events", and they cite an example using the "Application_BeforeApplicationShutDown()" event handler but I can't seem to get that one to work either.
Is there some way to turn these events on or make them call my handler?
Ok, thanks for helping a brother out,

Can anyone plz tell me what Hardware and software I need to use GPS on my windows application.I would most propably appreciate a list of all hardware and software necessary for my application to work, and possibly a step-by-step guidelines.
Programming is not a skill, it's an art.

Hi Arthur,
Either CodeProject or CodeGuru has a very nice article on interfacing to a piece of hardware. I don't recall the details - it has been too long. I recall the article impressed me.
Also, the hardware manufacturer probably has a SDK available. You might have to pick up the phone and call.

I have a problem making a new Data Source from VS2005. I have made a new
Widows Mobile 5.0 Pocket PC SDK Project. I’m going through Data
-> Add New Data Source… -> Database -> New Connection… -> Microsoft SQL Server Mobile Edition
(or through Server Explorer). I’m creating new database (or browsing existing).
The connection test ends with success and when I press OK I get such message box:
“Unable to find the requested .Net Framework Data Provider. It may not by
installed”
I have installed VS2005 with Widows Mobile 5.0 Pocket Pc SDK – no difference!
What’s wrong?

I am producing a mobile application using embedded VC++ 4 which contains multiple dialogs.
It was intended to step through the dialogs using a next button which would open the next dialog and close the current dialog. Also a previous button which does a similar thing.
The code used to open the next and close current is
Class2 dlgClass2(this);
nRetCode = dlgClass2.DoModal();
CDialog::OnCancel();
And for the previous button on the dlgClass2 button
Class1 dlgClass1(this);
nRetCode = dlgClass1.DoModal();
CDialog::OnCancel();
However by continually selecting next on the dlgClass1 and previous on dlgClass2 the application crashes after the 11th or 12th attempt.
Does anyone know please why this is happening? Are you able to close the current dialog or does it need to remain open?

DoModal creates a nested message loop. Eventually you get a stack overflow.
To avoid this, consider using the dialog's Create function. That creates a modeless dialog - messages are then pumped by the main thread's Run function (if all dialogs are modal) or by the most recent modal dialog on the thread.

Thanks,
