    - Preventing screen updates during initialisation? Due to the performance issues of Windows Forms on PPC, I am looking at the option of creating all forms during the initialisation of the main application form, or alternatively, creating all forms as required, but then maintaining the instance of the form throughout the life of the application. This is working fairly well and has resulted in much less flicker when showing a new form, either on the second showing or when all forms are created at the beginning. The problem with the initial creation remains however and even when creating the forms when the application starts, I am then seeing screen flicker whilst these forms are created even though they are not being shown. Is there a way to prevent the screen from accepting any updates whilst this initialisation is going on, and then reactivating the updates? Effectively, I am looking to "switch off" the screen whilst the forms are created, although I do not actually want to switch off and blank the screen. Cheers.

    - Using Internet Explorer browser control host (SHDOCVW) Hello, We want to be able to fire up and control IE from my C# ce.net app. We used the above control on earlier pc-based projects. I can add a reference to it for windows projects in Visual Studio 2003 (released version) but it is not available for ce.net projects. My target device has shdocvw.dll located in the Windows directory. I was wondering how I can access this functionality? TIA, Tom. Tag: .NET Compact Framework 1.0 Service Pack 1 (SP1) Tag: 1254

    - Adding Custom Component to Toolbox Hi, I've created a custom component for smart devices and I am trying to add this component to my toolbox through an installer. I've read previous posts and msdn documentation on using the DTE object and the various ToolBox collections within. I've been able to create a new ToolBoxTab but I am not able to add any items to this tab. For now, I am trying to add a Text item to the ToolBox (If this works, I will move on to trying to add the component). DTE myDTE = (DTE)Microsoft.VisualBasic.Interaction.CreateObject _("VisualStudio.DTE.7.1", ""); ToolBox myTBx = (ToolBox)myDTE.Windows.Item _(Constants.vsWindowKindToolbox).Object; ToolBoxTabs myTBxTabs = myTBx.ToolBoxTabs; ToolBoxTab myTBxTab = myTBxTabs.Add("MyTabName"); myDTE.ExecuteCommand("View.PropertiesWindow", ""); myTBxTab.Activate(); EnvDTE.ToolBoxItem myItem = myTBxTab.ToolBoxItems.Add("New Text Item", "Some text", EnvDTE.vsToolBoxItemFormat.vsToolBoxItemFormatText); myDTE.Quit(); myDTE = null; Any ideas?

    - Questions regarding sockets and threads I'm developing a server-client [tcp-based] system with the communication part utilizing the socket class. The server is PC-based [fixed ip address], while the client is pocketpc-based and is mobile[ip address might change?] and both are expected to be connected to a WLan network. Question: Would socketexception be thrown during connected communications between the two parties upon a change of ip-address to the client due to its mobile nature? Another question: What is the maximum number of socket connections that a listening socket can accept? Assuming a new thread is created to accept each socket connection request. And what is the maximum number of child-threads that a parent thread can create in the .net framework, if any? Tag: .NET Compact Framework 1.0 Service Pack 1 (SP1) Tag: 1244

    - Some Managed C++ experimants on Compact framework Hi everybody! Managed C++ is unsupported on the compact framework, but it seems to work to some extend anyway. I have tried to make a .NET libarary in MC++, and it works fine. Or at least it works fine when running it on a Pocket PC (emulator or real device) from Visual Studio. The only thing to keep in mind is to not use desktop framework specific functionallity. But when I compile the library to a stand alone DLL and then include it in a VB.NET PocketPC project I get the following error trying to compile (or deploy) the VB.NET application: Error: The dependency 'mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=969db8053d3322ac' in project 'Foo' cannot be copied to the run directory because it would conflict with dependency 'mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' What this error message says is basically that the libaray is depenedent on the desktop version of mscorlib and that the VB.NET app is targeted at compact framework. Therefore it refuses to compile. But... if I for example add the VB.NET app and the MC++ library to the same solution, I can run it on a real Pocket PC device if I start the execution from inside Visual Studio (pressing "Play"). Has anyone tried this with more success than I have had so far? Does anyone know if it is possible to tweek the MC++ library in some way so it claims to be depenedent on compact mscorlib instead of the desktop one? Maybe it still doesn'e work, but it would bring the experiment one step futher. /johan Tag: .NET Compact Framework 1.0 Service Pack 1 (SP1) Tag: 1220

    - Joke: You can't draw strings on a common base line ...unfortunately, it's not a joke. In the .NET framework strings are drawn using the top of the bounding box as the vertical coordinate, instead of the base line which is the *only* sensible thing to do (and which, therefore, Java's AWT uses). And in the compact framework the font metrics (that allowed for a work around by shifting the string) are missing, which leads us to the conclusion: you can't draw several strings properly aligned on their common base line. Am I missing something here (suggestions are very welcome), or have I just stumbled across another reason to abandon the .NET platform? Tag: .NET Compact Framework 1.0 Service Pack 1 (SP1) Tag: 1215

    - System.Threading.Timer - Does it Work? I have a need to code a timer in a class which will raise events periodically. The timer used is system.threading.timer and it works well EXCEPT when I call RaiseEvent to notify a windows form. There appears to be a deadlock occurring as I don't get control back to the class.

If i use the Internet Explorer on the machine it stays connected, so need to know how to start a permantent connection via GPRS with C# to use it within my application. I allready read a lot of postings on this forum, but i diddnt manage to find a post which fits my needs.

    - Visual Inheritance & compact framework? Hi, Does anyone know how to make Visual Inheritance work using VS.NET 2003 and the .NET Compact Framework? A marketing article on msdn said its one of the benefits of VS.NET over embedded programming...However, I can't find out how to do it. I went through a walkthrough for a normal application where I created a base form in a class library. I then created a standard windows app & added a reference to the class library. Then I (per the walkthrough) click on the project --> Add Inherited form. This is for a non-"Smart Devices" type of project. When I follow the same for a "Smart Devices" type of project I do NOT see the option to add an "Inherited form". I thought I'd try to go a little and changed the "inherits system.forms........" line to "inherits myclasslib.frmbase" BUT after doing this, I couldn't go to the design mode of the form to add a new button??? I'm hoping that this is one of those scenarios where the option I'm looking for is right in front of me...but..........help! Anyway? I'm actually looking at this functionality because I want to create a bunch of forms that share common features like menues, certain labels,.....

    - Deployment Newbie Hi all, I am new to the world of developing for the compact famework, and have recently finished my first application. The only problem is, I am having a lot of difficulty figuring out how to create a deployment project. One that deploys to the desktop computer and uses active sync to add/remove programs with the pda. I have been trying to follow the process outlined in the msdn document found at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetcomp/html/netcfdeployment.asp or http://microsoftdev.com/Learn/Articles/566.aspx but am finding that it doesn't provide enough detail. I have since tried several third party deployment wizards, settling on the Wise include for VS 2003, but have still been unable to compile a successful deployment project. Basically, I was wondering if anyone knew of any step by step walkthroughs for creating a deployment package (using VS or Wise or any other vendor) that provided more detail than that of the afore-mentioned msdn articles...

    - Differences between ipaq and Axim and the CF All, We are experiencing a very strange issue; a CF application, written for and tested on Dell Axim's (Pocket PC 2002) works as expected. We then began testing on Compaq Ipaq's (5450 and some older models), all with Pocket PC 2002. The ipaq 5450 and Dell Axim's have the same specs (processor type and speed, etc). The application will not run on the ipaqs; it fails during the load sequence. In debug mode, we isolated the issue around setting properties on the CFCOM component (3rd party tool from Odyssey) which hosts the Windows Media Control. As aforementioned, the exact same code base works as expected on the Dells. As far as I know, the CF should behave the same regardless of the hardware platform. Any ideas?

I am wondering whether this is related to the thread modelling on the evb. Is there anyway while the while loop run, i can also have the button functioning at the same time?

    - C# HTML Renderer - Any interest? All, I have developed an HTML Renderer for the compact framework written entirely in C#. Since there is no pIE or rich text control, I just had to do this. It supports a subset of HTML (no scripting, or CSS, your HTML must be parsable by the CF XmlDocument class), but it allows one to have a reasonably rich user-interface without having to use unmanaged code hooks into pIE. I wrote it as part of a project I'm working on but my boss is open to offering this component to other developers who may be in need of a managed HTML Renderer. I told him there may be a market for it, so I'm asking you guys out there if there is any interest. If there is interest, I'll put some screenshots of it up on the net for you guys to look at. IMHO, this functionality should have been included in the core framework. -Bruce Shankle eshankle AT nc.rr.com (replace AT with @) Tag: .NET Compact Framework 1.0 Service Pack 1 (SP1) Tag: 1072

    - Virtual ListView using the Compact Framework? Okay, I've got a question for you folks. I'm currently working on creating a C# version of Tillanosoft's TGetFile open/save dialogs (they don't work with C#, and I'm a cheapskate anyway). I've managed to solve the majority of my problems, mostly through insane amounts of Googling, but this one I haven't been able to find an answer for. The major timewaster in my dialog right now is adding files into the ListView.ListViewItemCollection. Since the CF ListView doesn't have a .Sort() method, I've been doing sorting on my own, and managed to get it pretty fast. However, this means I have to .Clear() the ListView each time I sort it, and .Add() every item back into the list in the newly sorted order. I've been testing my dialog against the \Windows directory, which currently contains about 750 items. Adding those 750 items into the ListView can take anywhere from 5600 milliseconds to 11000 milliseconds - far too long to be acceptable. As a result, I've been reading up on "virtual listviews". I understand the basic concept of them, and even found an example in C# at windowsforms.net. Here's where my problem comes in. The example I found overrides the .CreateParam sproperty and sets its style to LVS_OWNERDATA, which is necessary for it to be a virtual listview. Naturally, the Compact Framework ListView doesn't support .CreateParams, and apparently doesn't support other styles either. So, here's my question: is there ANY way possible to set the Compact Framework ListView style to LVS_OWNERDATA? I can get a handle and do a SendMessage if necessary. Any help would be GREATLY appreciated, including possible ideas for optimizing adding ListViewItems or other techniques for doing a virtual listview with the Compact Framework. If this can't be done, well... does anyone have any suggestions as to how to go about creating my own ListView control that I could make virtual, something like wrapping the MFC or built-in ones? I think the biggest issue there would be trying to dealing with all the messages and handling the imagelists and stuff. I really don't want to have to do that if I can avoid it. Anyway, thanks in advance for any help you guys can provide. Mark Erikson Tag: .NET Compact Framework 1.0 Service Pack 1 (SP1) Tag: 1068

    - Using Spb Kiosk Engine for eVB and .NET CF Pocket PC enterprise applications - (DEVBUZZ) Hi all, There is a growing trend for Pocket PC's to be used as special devices in a very restricted way with many functions disabled and with only one application executing - this is called kiosk mode. A lot of vertical market applications require kiosk mode. It can for example disable all games and other entertainment programs on Pocket PC. This article describes how to create eVB and .NET CF kiosk applications for the Pocket PC using the Spb Kiosk Engine. http://www.devbuzz.com/content/zinc_spb_kiosk_engine_pg1.asp -- Regards Derek Mitchell news@devbuzz.com NET Compact Framework Tutorials: - http://www.devbuzz.com/content/init_compact_framework.asp eVB Tutorials: - http://www.devbuzz.com/content/init_starting_out.asp Pocket PC Development Forums: - http://forums.devbuzz.com/ Code Snippets: - http://www.devbuzz.com/content/code_snippet_list.asp Tag: .NET Compact Framework 1.0 Service Pack 1 (SP1) Tag: 1055

    - How can i get data more fast in tokening the data? Hi.. PDA received somedata from server(desktop PC) using socket communication. After received the data, i separate each data from the received data. my source code is below. Server sent the data which is combined about 1000 data. In my source code, for(int i = 0; i<data_count; i++) { .... } it takes long time to separate each data regardless of listview. To tokening the data is originally slow in CF? How can i resolve it.. get data more fast? Or if i receive the data using file, how can i use it? //////////////////////////////////////////////////////////////////////// receive_data = reader.ReadLine(); if (receive_data != null) { receive_data = receive_data.Remove(0,1); commandstr = receive_data.Substring(0,2); if (commandstr != "02") { MessageBox.Show("ERROR"); return false; } receive_data = receive_data.Remove(0,2); data_count = Int32.Parse(receive_data.Substring(0,4)); receive_data = receive_data.Remove(0,4); for(int i = 0; i<data_count; i++) { areastr = receive_data.Substring(0,3); receive_data = receive_data.Remove(0,3); indatestr = receive_data.Substring(0,10); receive_data = receive_data.Remove(0,10); intimestr = receive_data.Substring(0,8); receive_data = receive_data.Remove(0,8); outdatestr = receive_data.Substring(0,10); receive_data = receive_data.Remove(0,10); outtimestr = receive_data.Substring(0,8); receive_data = receive_data.Remove(0,8); monstr = Int32.Parse(receive_data.Substring(0,6)); receive_data = receive_data.Remove(0,6); totmonstr = totmonstr+monstr; instr = indatestr.Substring(5,5)+"/"+intimestr; outstr = outdatestr.Substring(5,5)+"/"+outtimestr; ListViewItem item1 = new ListViewItem(areastr); item1.SubItems.Add(instr); item1.SubItems.Add(outstr); item1.SubItems.Add(monstr.ToString("#,##0")); listView1.Items.Add(item1); } } /////////////////////////////////////////////////////////////////// Tag: .NET Compact Framework 1.0 Service Pack 1 (SP1) Tag: 1049

    - Dynamic Controls...how to ID? I have wrote my own icon class that places a bmp and two lines of text onto a panel. These icons's are created dynamically and represent positions on a map. I want to be able to click on the icon and use the icon as an index to the data it represents. IE. click on it using a contextmenu and be able to edit, move, and delete the icon. I am able to actually put it on screen, add the contextmenu and select its events, but my question is how do I know what the ControlNo is for the icon I am selecting in the panelField.Controls list? Should I create an array to store these controls in? And again how would I be able to extract the Icon no in the ArrayList so that I can delete it from the array, etc.? Basically touch that specific icon object in the heap... Thanks as always peoples.... doogman Tag: .NET Compact Framework 1.0 Service Pack 1 (SP1) Tag: 1047

    - Help with Connection Manager PInvoking Greetings, I am having difficulty calling the ConnMgrEstablishConnection function through PInvoke which I hope somebody can assist with. I have used the CMHelper project in the PPC2002SDK as a basis for this code. The call to ConnMgrMapURL works fine, but when I try and call ConnMgrEstablishConnection (via the EstablishConnection function below), I get a NotSupportedException. I suspect that it may be a problem with the ConnMgr_ConnectionInfo structure (eg. data types). I had tried hWnd and lParam with Integer data type as well with the same effect. My call to ConnMgrConnectionStatus also achieves the same result but possibly because I do not have a valid handle. Thanks for any help anybody is able to provide. Regards, Justin Marshall.
