    - PictureBox - Loading/Viewing JPG files I have some code that loads JPG files into a PictureBox control. It works fine if the file is small, but files over 100K cause an Argument Exception error. Since the compact frame work does not have: picbox.image.fromfile("...") I had to do it this way: Dim MyImage As Bitmap MyImage = New Bitmap(OpenFileDialog.FileName) picbox.Image = CType(MyImage, Image) It fails on New Bitmap(). Iâ??ve seen other message threads about these bit map size problem, but no solution. How can I view these larger files on my hand held? IE seems to handle it. Thanks.

    - color.fromargb in .net compact does not paint transparent Hello, When I use the microsoft example below and run it, it produces 3 circles which are more or less transparent. When I use the exact same code in .net compact, I see 3 opaque circles. The MSDN information does not mention anything about not being able to draw transparent images.

    - 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. I other posts people have referred to CESpy, which I am not familiar with, but am currently attempting to locate. Tag: update ComboBox: flicker problem Tag: 18520

    - VS 2003 freezes when bringing up GUI from code this is -really- weird. i built a GUI yesterday that included buttons, text boxes, labels, a menu, image list, and picture boxes. nothing fancy, just basic stuff. when i tried to open it today VS 2003 just froze. but when i create a new project, copy over my old .cs and .resx files, and then bring up the GUI editor and the source code, it's fine. unless i exit w/ the GUI editor still open, and try to open it again, then i have the same problem. VS 2003 also freezes when i open the old project and i don't have the GUI editor open, but then try to bring up the GUI editor from the source code. has anyone seen anything like this?? i'm running on win2k if that makes a difference. thanks in advance.

    - 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: update ComboBox: flicker problem 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: update ComboBox: flicker problem 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.

    - PPC 2003 & 2002 Emulators both launch I've just installed the PPC 2003 SDK, and would like to run my existing project using the new 2003 emulator. I have set the project to use 2003, but it still insists on launching the 2002 emulator first. Weird thing is, it installs .net & sqlce on 2002, copies the application over to 2002, and then also copies to 2003, finally launching the app only on 2003...aarrgghh I can create a new hello world app using 2003 and it works just fine....

    - messagewindow not listening after losing focus Hey guys, I have 2 CF apps where one sends message and the other listens through a messagewindow. The problem occurs when focus is taken away from the listener app (e.g. by starting up another app), from that point on the messagewindow no longer receives messages even though the sender app is still sending them. I was wondering if any of you have run into this problem or have ideas as to what's going on.

    - SqlCeRemoteDataAccess Pull Im using RDA (SqlCeRemoteDataAccess) to retrieve data from a remote sql server to a pocket pc device It works no problem, in that if no sql server ce database exists on the device the pull method retrieves the required data and creates a local sql server ce database The problem I have is refeshing the data I initially retrieved. I have tried using the same code but it fails. Now if before using the same code i delete the sdf file off the file system and then use rda pull again it works fine. I tried leaving the database intact and dropping the local table i want to refresh and then trying rda pull again but that fails too So it appears to use rda pull the database must NOT exist and the call to pull creates the database. The problem i have is that there are numerous tables in the local sql server ce database and i only want to refresh the data in a couple of tables rather than retrieving the whole database as this is not required. My question really is just to confirm , can you use rda pull to refresh data in a local ce database file that already exists. My experience leads me to believe you can't but could someone confirm or deny this THank An Tag: update ComboBox: flicker problem Tag: 18420

    - Interrupting Events from within Parent Control Hello, ive got the following problem, which i hope gets solved here. I ve got a Form with a Number of Controls in it (Button, Listboxes and Textboxes). The user can use a config-file to control the output target of an attached scanner. If i use the scanner while a Textbox is focussed, the scanned code gets inserted into that textbox. My problem is, that i need to decide where the scanned code gets put to. For example, if the output target is Textbox 'A' and Textbox 'B' and Button '1', then the scanned code has to be atttached to these three controls. Dows anyone knows how to intercept a Keypressed event for example on a parent control(Form), since all the controls i mentioned above, are added to the Form. The reason for this is, that if the scanner is used, i want to decide in this one event, where to put the scanned text to and even if i handle the scanned code in any way. Thanks in advance Greeting Jens Meyer Tag: update ComboBox: flicker problem Tag: 18356

I have installed SP2.

I have a screen with many Controls (setting some property values), one of
them being a ComboBox.

At some stage I should update the DataSource and SelectedItem of the
ComboBox (when the user change a setting with another Control)

the problem is even thought I change this 2 property one after the other, in
the same event handler, my combo flicker. when I set the DataSource it
redraws, then I set the SelectedItem it redraws again, which looks messy.

Is there a way to do that in a clean way, from the user point of view ?
