    - New Bitmap causing exception Hi, I'm getting a SystemUnAuthorised exception with the following bit of code, separated out for clarity Dim memStr As MemoryStream memStr = New MemoryStream(imageptr) picBox.Image = New Bitmap(memStr) <- exception here Strangely it doesn't get caught by the Try Catch block but only by the debugger. In the call stack window it seems to be in mscorlib.dll Sytem.IO.memoryStream.GetBuffer. imageptr is obtaimed from reading a an image file which i've checked is not readonly. So why is the BitMap constructor call throwing this exception. Tag: How can I set the system date ? Tag: 72200

    - Kill TS Client... Kill, Kill Hi, We have a problem connecting to our Terminal Server via PocketPC. After a bit of research, I found out that it's because the registry key that holds the license information is corrupted somehow. The fix for this is to delete the registry key and warm boot the device. Except I don't want to warm boot the device. As far as I can tell, what I really have to do is make sure that the existing TS client is terminated - so that it takes notice of the change in the registry settings when it loads up. My question is, how do I make sure the TS client is no longer resident in memory? Is TerminateProcess my only option? If so, does anybody have an example of using TerminateProcess in C#?

    - .NET Framwork and VB Hi, I have recently started coding and designing the ,.NET based system using different technology involved in .NET and well from the subject line of this post, it is obvious that I am coming from a VB background. I have many years of expirance in designing distributed system based on VB, C++ and SQL Server but when I have tried .NET it is a complete new exerince for me and I am not hesitant in saying this is a damm cool stuff from MS. Now in this regards, I got a question but I am really not sure what is the case in .NET. In earlier days, when I used to design classes based on limited VB object based model, we used to create 2 different callses for one business component. One class which is used for all database read operation and another for database write, update and delete opeation. Now, why we were doing this so because of the locking in database via VB programs. if all database select operation id seperated from database write operation it palces less locks and almost comes out immediatly by removing database locks (Offcorse when all the VB dlls are regirsted in COM+). Now I wanted know is this still applicable in .NET. For example, if I want to write a Cusomter business component, do I still have to seperate out the select and updates in seperate classes. In earlier days, I used to designed a dll with following classes. CustomerRead (Main class to read, exposed to world) CustomerWrite (Main class to write, exposed to world) CustomerSingleSelect - a calss which gets data from customer based on primary key and always return me a sigle row CustomerMultiSelect - a class which gets the data from customer where select operation is not based on its primay key. CustomerModify - a class to modify customer. Belive me this approch was much faster then everything in one class. But this was the case in VB time. Does this still a case in .NET?

    - Application wont exit Hello All, Im having a problem getting my app to unload from memory. it starts with a sub main, that essentially goes: Dim f as myForm f.ShowDialog() Application.Exit now, it IS getting to the application.exit statment (tested with a MsgBox statement earlier), but it just WONT unload. It LOOKS like it does, all the forms go away, and if i check the Running Programs list, it is not listed anymore, but the terminal just sits there with its little "hourglass" thing going and going ..... and it maintains a lock on the executable file. Very frustrating for development because i have to reset the device before i can copy on a new version, which means having to re-establish a stupid activesync connection too. Rather tedious. Any idea why it would not exit even though it appears to? VS2005, CF 2 Thanks in advance, Arthur Dent. Tag: How can I set the system date ? Tag: 72108

    - Inherited Forms and menus Hello all, I have a small application which has a base form, and forms inherited from it. The base form contains a barcode scanner, and a protected event it raise when the scanner reads data, and the inherited forms can get the scanner and catch the event with no problems at all. My problem comes in, with a mainMenu which i have on the base form, which i expected to see show up on the inherited form, however, it doesnt. This was kind of the whole reason why i wanted to use a base form, was so i wouldnt have to duplicate the same menu on a bunch of forms, with duplicate code. Why does the menu not show up, is there a reason? Anyone know how to fix this? Thanks in advance, - Arthur Dent. Tag: How can I set the system date ? Tag: 72096

    - Beaming data Hi all I have an Intermec on which I am developing a dotnet V2 app. At some point during the day two members of staff may meet and decide to exchange stock. To ensure that there is no fraud I would like the PPCs to talk to each other and negotiate a level of stock to transfer. Eg 01) Person A enters brands + amounts of stock to transfer to Person B 02) Person B (waiting in the "Receive stock" form) gets a signal from Person A's PPC with the data 03) Person B reads the data and accepts or rejects 04) If Person B accepts then A and B both update their DB with the stock transfers I am not sure if I can enable the bluetooth or not, because I think doing so disables the serial connection and I need that for printing (although I may be wrong). Can I do this with the infrared beaming functionality? Does anyone have any info or links on inter PPC communications? Thanks Pete Tag: How can I set the system date ? Tag: 72094

I don't know why this is so difficult to find. I can go to a Cingular or sprint website, enter a persons phone number and a short message, and the web page will take this data back to the web server where it will be routed to the wireless device.

    - Memory mapped IO to PCI driver Hello, I like .NET CF 2.0. I love speed. I need both. Situation: PCI device on CE 5.0. Memory mapped IO connectivity to device. Desires: o I want to have my driver init routine return an address pointing to the user mode address of the memory mapped region in the hardware. o I want to PInvoke into this code to grab that pointer and load it into an unsafe block in c#. o I want to manipulate things in the hardware via .NET by using this unsafe block to change values in the memory region I got from the prior step. I think this all works, but I am not peaked on the performance issues. I belive that I can avoid all the pinvoke business this way (except for the first one that sets things up) and do fast .NET access to the hardware. Can anybody comment on my peculiar approach?

    - Problem with socket communication for client (On handheld) / server (on PC) application Hi, Sorry, I'm reposting this as unfortunately, it's quite urgent, and I hope someone out there can help... have a client application running on a windows ce .net device, and a server application running on a PC. I have been experiencing problems with the tcp connection dropping (ObjectDisposedException for the NetworkStream) and so I have tried to cut the applications down to their minimal details, so that I can post them and ask for your opinion on the problem. The client sends commands to the server, and the server sends a response. The tcp connection is opened at the start of the communication, and is kept open between commands - i.e. a new connection is not opened each time a command is to be sent. I have now configured the client, when the button on the main form is clicked, to send a command (just a longish string) to the server. When the server receives a command, it sends the response (just another arbitrary string in this example). I have used a loop on the client side to send the same command up to 500 times. At about iteration 70, I get an ObjectDisposedException, and the server reports that the connection was closed on the client side. Now an error occurring every 70 times may not seem that often, but in the real application, I am scanning a barcode, and on the basis of that, running stored procedures on the server, and the amount of data going back and forth is more than in this example. I am getting an error every second scan or so, which is definitely not acceptable. I am assuming that if I can solve the problem in this simple example application, then the (hopefully exact same) problem in my actual application will also be solved. The exceptions happen both when the client handheld is connected to the PC via activesync, and the local lan ip is used to connect to the server, OR if the client handheld is connected via a wireless lan access point when NOT connected via activesync. Sometimes an IOException occurs instead of the ObjectDisposedException. But an exception occurs without fail, after some iteration of the loop. The same happens when using the emulator. An important point is if I make a PC client application, using the same code as the handheld client application, is successfully sends and receives the 500 commands and responses, whereas the handheld and emulator only make it to about 70. The code is below, I'd appreciate any help, I have no idea why this is happening! I thought that maybe it would have something to do with a memory problem, but I'm not sure if this is the case. I have tried running GC.Collect() after each iteration, but this just makes the exception happen immediately.

    - Switching Panels using Visible =true & Visible=false; Hi, I'm developing an application on PDA using WindowsCE. In my application I have several tabs at the bottom of my screen. However, in one of the tabs I've placed 2 radiobutton, used to switch between between 2 panels on that same tab. (I don't use nested tabs, because I noticed they always show at the bottom, which is unlogic in my application). The first Panel is a custom Panel in where I override the paint method to paint a curve. The second Panel is dat datagrid which shows a detailed list of the points shown in the curve on the first Panel. The 2 radiobutton are there to switch between those different views. to switch i use the following code. curvePanel.Visible = false; dataPanel.Visible = true; or the other way around. Problem is that when the dataPanel.Visible is set to true, the application hangs big time. Is there somebody who knows why this happens, and what I can do about it? I've been trying to fix this for over 3 days now, no luck yet. Greetins, Kristof. Tag: How can I set the system date ? Tag: 72032

    - Textbox and Timer problem Hi, I am experiencing a strange problem while developing a smartphone WM5 application. I have 4 textboxes and a timer that updates these textboxes. The textboxes enabled is set to false so the user cannot modify them. This works fine and the timer updates the textboxes correctly. I added another textbox (enabled=true) and all of a sudden my other 4 textboxes don't get updated anymore. I set a breakpoint in the timer function and the code never even enters the timer tick event. My timer is enabled..it's something with these textboxes that i can't figure it out. If i set the new textbox to enabled=false then it works again. Anyone know why this is happening. Thanks, Felix Tag: How can I set the system date ? Tag: 72023

You have to P/Invoke SetLocalTime or SetSystemTime.

Take a look at the DateTime2 class in the SDF:

Hai,

do you want to set the system date means,

simply assign the today property with your date. ie., like this

today=dtpcontrol.value

it will change the system date also.

Raj.
