    - Connection to SQL Server I am a VB6 programmer starting out in vb.net. I have been trying to connect to a SQL Server database using SQLClient from a pocket pc, but am unable to connect. my code is: cn = new System.Data.SqlClient.SqlConnection cn.ConnectionString = "User id=sa;password=password;database=test;server=192.168.0.2" cn.Open() However, the connection always fails with the error "SQL Server does not exist or access denied". I am running the emulator on one PC, the SQL Server is on another PC in my network. I am assuming that the emulator can 'see' the other PC, since I can open a terminal server client from the emulator to it. I wrote a 'normal' vb.net program with the same code and that connected straightaway, so I am assuming the connection string is okay. This ran on the same machine the emulator is on. So I think it must be one of: * the pocket pc can't use the same sort of connection string as a normal pc? * the link to sql server from the emulator is different to the link to the same machine using terminal server client? Does anyone have any ideas? Olli Tag: how can do this development. Tag: 18693

    - Easy deployment of pocket pc application Hi, I've developed a pocket pc application for .net. I've not encountered any major problems during the development and think that Microsoft have successfully converted the .net platform to pocket pcs. We aming for a easy installed application, but that seems to be wishing to much... To run the application you need to install(some with installer on pc desktop and some copy .cab files to PPC): My application .net compact framework sp2 SqlCe HP printing sdk Intermec print sdk optional: TomTom and TomTom .net sdk Have anyone encounterd the same problem and have any recommendations to get it "smoother"?! We thought of having all cabs in one installer, but there probably will be problems with ULAs.

    - ShowDialog working semi-modally Hi, I'm creating a dialog that needs more controls than a simple MessageBox. I don't want it to take up the whole screen and I would like it to be movable by the user (just like a MessageBox). I've created a Form and set FormBorderStyle to None. I call it using ShowDialog. ShowDialog is modal and blocks the calling form - that's good. The Dialog box works fine. The problem is that if I click on an area outside of my dialog box, my dialog box loses focus and the calling form is brought to the front. How can I block any clicks outside of my dialog box while it's open? Thanks, Bill Albert ObTech Tag: how can do this development. Tag: 18671

I am needing to display formatted text (bold, change font, color, highlight) but also allow the user to select the text and my program recognize and FIND the selected text and where the cursor is at in the text like a regular text box (but not allow any editing). I am currently using the free browser control from the OpenCF group. I can format my text coming in by adding HTML tags and it works great BUT there's no selected text index and I can't find out where the cursor is at since it's a browser control.

    - Regional Settings Problem / SQLCE money Type Hi guys, im having a problem with CF and SQLCE. ill try to explain it: The Decimal Value in VB.Net(with regional settings to english) is something like 10.98, it uses the dot to split the decimal part. In the VB.NET i work fine with this value. When i convert 10.98 i got 10,98 cuz my regional settings is pointed to Portuguese(Brasil). When i try to record the 10,98 in the SQLCE money field, it brings me and error. I was sending the 10.98, and got no problem. But with the 10,98 in the string the SQLCE assumes that there are two fields. Anyone knows how to send values to SQLCE expliciting they r money values? Or to change the regional Settings logically? Or any other way to do such thing? Thanks, Felipe Tag: how can do this development. Tag: 18615

    - SqlCeDataAdapter.RowUpdated event Can anybody explain to me why after calling SqlCeDataAdapter.Update the RowUpdated event is called but the error information seems incomplete? In the event hander RowsEffected sometimes = 0 so I get the idea that there has been an error, as a succesfull RowUpdate in my case should have 1 row effected. If I dont set the event argument Status to System.Data.UpdateStatus.Continue an Exception is generated which in my case often tells me there is a primary key constraint problem. However if I set Status = System.Data.UpdateStatus.Continue no exception is thrown (as expected) but nor can I get detailed error information in either the event handler or the function that called Update. I dont understand why it isnt available in the event handler since the Row is meant to already had been attempted to be updated. Any ideas? Thanks Josh Tag: how can do this development. Tag: 18603

    - localizating controls ? Hello, I'm trying to find an easy way to localize control's Text properties. For instance I could replace the following code: void InitializeComponents() { ... this.m_Label1 = new Label(); this.m_Label1.Text = "Hallo Welt !" ... } with this code: void InitializeComponents() { ... this.m_Label1 = new Label(); this.m_Label1.Text = Resource.GetString("Hallo Welt !") ... } In which Resource.GetString() is a static function searching the calling assembly's resources for a translation of "Hallo Welt !" depending on System.Globalization.CultureInfo.CurrentUICulture. Unfortunately, editing InitializeComponents() would render the designer useless. So that method is out of question. The next solution that comes to mind is to set all translatable text again after InitializeComponents() has finished. But this is cirumstantial, fault-prone and time-consuming (both, run-time and design-time). Another approach would be to extend all standard controls so that they call Resource.GetString() automatically. How would you or did you deal with this problem ?

    - Yet again a much asked question: full screen Hi, I am reposting my question of a few weeks ago because I got no response. I was using this CDialog based baseclass STFullScreen from http://www.pocketpcdn.com/articles/stfullscreen.html This worked fine on PPC 2002 but seems ineffective under PPC 2003. It seems PPC 2003 behaves different enough with hiding start and sip menu's and perhaps with windows positions or whatever, to cause my PPC 2002 app to become useless. In CE 4.2, my application comes up in full screen, but as soon as I click anywhere in the screen, the menu bars appear again, and for some reason, I can't even exit my application anymore, buttons click, but do not seem to process messages, as the buttons animate, but do not seem to process the on_click messages. Anyway, those are specifics to my source code and the above mentioned base class I think so in general: Can someone just tell me how to, or reference me to some resource, where I can make full screen DIALOG BASED apps, which work on both PPC2002 (CE 3.x) and PPC2003 (CE 4.2) ?

    - MessageWindow Consternation with HTMLControl I am looking for some thoughts on this. I have successfully gotten the HTMLControl to work using C#, and it is displaying HTML and receiving messages nicely. Unfortunately, I am not able to receive notifications from the HTMLControl. In an attempt to support this, I added a private MessageWindow derived class to the control, instantiating it in the constructor (of the control). Unfortunately, I am not receiving any messages from the HTMLControl. I do receive a single message on the initial load of the form (13) but not from the handle of the display window the control is using. I have not found much documentation on the MessageWindow, aside from the NotifyIcon example - which I followed. I thought that adding notifications would be rather simple when looking at that code. So, I am looking for thoughts on how to debug this - or where to look next. My options seem straight forward: 1. The control isn't producing messages and needs some initialization to do so. 2. It is producing messages but not directing them to where the MessageWindow can receive them. 3. The MessageWindow should be receiving them, but isn't properly setup to do so.

    - accessing VC ActiveX from .NET Hi All, I have created an ActiveX control using VC 6.0. One of the interface implements a method which takes in VARIANT FAR* as the parameter. Iam unable to call this method from C#(.NET 2003) no matter what.. I can call the same method from VB 6.0. I have been bogged down by this problem for quite some time.. I dont have a clue what to do.. The funny thing is that I created a VB stub (again an ActiveX with method taking byref Variant), which calls the earlier mentioned VC activex method with the parameter passed to it. If I call the above VB method from C# using "ref Object" param it works fine!!! Following is the code: C# static void Main(string[] args) { VBActiveX VB = new VBActiveX(); VCActiveX VC = new VCActiveX(); Object OOO = new object(); VB.TryThis(ref OOO); // This Works!!! VC.TryThis(ref OOO); // This gives Exception "Catastrophic failure" } VB6 Dim VC as New VCActiveX; Public Function TryThis(ByRef A As Variant) VC.TryThis(A) ' This Works!!! End Function VC6 short VCActiveX::TryThis(VARIANT FAR* Var) { MessageBox( "What is Wrong???", NULL, MB_OK); return 0; } Similar to this problem, I have a third party ActiveX (VC6) which has a metthod with the same signature(VARIANT *). On calling this method from C# an exception "Type Mismatch" is raised, where as from VB6 it works alright???? So where am I going wrong.. thanx a million in advance Niranjan Tag: how can do this development. Tag: 18480

    - Send a file over a TCP network connection Hi, I posted a question a while back relating to sending data over a network, and was told to go and look into how networks send data. I know that TCP can not guarentee the order in which data is delivered to a device. In light of this, I have a problem which I can not find a way out of: I need to send a file of around 4-5Mb over a network. To prevent communicaiton thread being locked, I was attempting to segment the data into 8k segments of data to be sent. In the header of each segment, I was attaching a 4byte integer representing the segment number, which will allow the reciever to place the data in the relevant position in the output file. Occasionally the client decodes the segment identifier into a bizzare value (last time I tried this, I was expecting to see segment number 234, and recieved -432352 or similar). However, this is not working,and the data being written out to a file at the reciever is not the same as the input data at the server. Why would this be? Please can anyone shed any light on this matter, or show me an example of how I should send the data/ensure that the data at the client end is pieced together correctly? Many thanks for any help - I am very confused by this matter. David Tag: how can do this development. Tag: 18478

    - Usual Values for WebService.Timeout? Hello NG! The default for the timeout of an WebService is 100 seconds. I think, this is a long time to let the user know, that the server isn't reachable (with the specified url). So what are usual values in a scenario where mobile devices connect to a server over the internet? I thought of maybe 20 seconds? In my experience thee timeout-value affects only the allowed time to get the first contact to the server. Afterwards it isn't important, how long the WebMethod takes for calculating the result, isn't it? Do client and server 'talk' to each other while the result is calculated?

    - Unable to connect with web service first time. Hi. Im using web services and my two questions are the following: 1. The first time the web service is called it always seems to generate a "Culd not connect to remote server". Any calls after that goes fine. 2. If connection is available then the first call to a web service is much slower than calls after that. Is this to be expected? Are there workarounds. Note: Im using Visual Studio .NET 2003 and the emulator only to try this. Haven´t tried his on a real piece of hardware yet. Regards <P> Tag: how can do this development. Tag: 18469
