    - Shifting around forms. Actually, I am having this problem long time ago. It applies to both of my VB.NET programming and the Compact Framework. Like what we can do last time in VB6....instead of closing a form, we can temporarily hide a form and shift to another form. After that, we can get back to that old created form easily by asking it to show. However, this seems not to be the situation to me in .NET framework. I don't know how to refer back to a old created form instance. To create a new instance, I will: Dim frmTest as New frmTest frmTest.Show How about not to close an instance and to refer back to that instance? I am very grateful to someone out there who is willing to help me on this. Thank you. Tag: Tab control Tag: 27157

    - help with datatable I am having trouble with getting at the last record in a datatable. I need to find the id and increment it. int x = logtbl.Rows.Count; string x_id = logtbl.Rows[x]["fldid"].ToString(); //here it tells me that x_id has a null value because no row exists at (x = 8) int id = Convert.ToInt32(x_id); MessageBox.Show(x_id); Is there an easier way to accomplish this.

    - Adding picture/icon in ListView Control I cannot find the way to attach a picture/icon to my items in the listview control even it was set to be shown in small items view. The command I am using is: ListView.Items.Add(New ListViewItem("xxxx", 1) where "xxxx" is a string and 1 is the listing no of my icon in the image list. However, the system is prompting error on that. Other than that, I cannot show a picture on my message box also, like what we could in vb.net, vbquestion/vbinformation.....those kind of pictures. Is there anyways to do it in compact framework? Thanks, to whom are helping me with the above matters. Thank you. Tag: Tab control Tag: 27142

    - Tabpages order in Tab Control In order to speed up my application, I try to apply the tab control more oftenly to reduce forms opening. However, after maybe somewhile of debugging, I found the sequence of tab pages shown up while debugging was not following the way it was designed in the design mode. How could this happen? Is there any ways I can fix the sequences of my tab pages? Furthermore, this situation appear in my listview control also. The icons (in the large icon view) found to be in different sequences as they were designed also. Many thanks to whom is going to help me on the above problems. Thank you. Tag: Tab control Tag: 27141

    - No DNS server Sorry if this is a repost, I don't think the first on sent. I have made a program that runs on a .net PocketPC that talks over a wireless network with a server running a program that is not written in .net. The program works fine here, but gives an error message of "No such host is known" at the customers location. I do not think they have a DNS server at their place. In csharp how do you connect with TCP to a server without causing a DNS lookup. Here is the code I am using now. Not that ServerAddr is a string containing the valid IPAddress of the server. socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); socket.Blocking = true; IPHostEntry IPHost = Dns.GetHostByAddress(IPAddress.Parse(ServerAddr)); string[] aliases = IPHost.Aliases; IPAddress[] addr = IPHost.AddressList; IPEndPoint ipepServer = new IPEndPoint(addr[0], Port); socket.Connect(ipepServer); I can give you the output of IPConfig run from the server if it will help. Also I can ping the server from the pocketPC so I know it can see it. Tag: Tab control Tag: 27130

    - Networks with no DNS I have written a .net program that runs on a pocketPC that talks wirelessly to a non .net program on a sever though sockets. The program works fine on our network here, but on the customers it gets an exception "No such host is known". I do not think their network has a DNS server. Here is code I use to connect. The string ServerAddr is the IP address of the server in string form. socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); socket.Blocking = true; IPHostEntry IPHost = Dns.GetHostByAddress(IPAddress.Parse(ServerAddr)); string[] aliases = IPHost.Aliases; IPAddress[] addr = IPHost.AddressList; IPEndPoint ipepServer = new IPEndPoint(addr[0], Port); socket.Connect(ipepServer); If it would help I could give you the results of IPConfig when run from the command line on the server. I can also ping the server from the PocketPC so I know that it can see the server. Tag: Tab control Tag: 27126

    - How to resize PictureBox image Does anyone know how to resize an image in a PictureBox? I have been able to resize an image using Graphics.DrawImage in OnPaint, but CF does not support the CreateGraphics method for a PictureBox. I can select SizeMode in a PictureBox and that handles the different mode requirements that I have, but CF does not support SizeMode for anything but a PictureBox. If I could get the image associated with the Graphics object after I draw it and then pass that to the PictureBox, that would suffice, but I can't seem to find how to do that either. Any ideas will be appreciated Tag: Tab control Tag: 27118

    - How to get path to Templates folder? Is there a reliable culture neutral way to get the path to the built in "Templates" folder? Obviously P/Invoking SHGetSpecialFolderPath won't do the trick because it doesn't return the Templates folder path. I have an app that uses templates and documents similar to pocke word so I want to implement the Pocket Word method of sticking templates to the templates folder and regular documents elsewhere, but I have yet to find a reliable way to determine if a folder is the official Templates folder. (i.e. non english platforms obviously won't call it "templates" and a user could easily make a "templates" folder elsewhere confusing the issue) Tag: Tab control Tag: 27112

    - What to Use? I have a large maintenance system running in paper mills. We are moving towards Pocket PCs for the collection of lubrication and inspection information of the equipment. I am a seasoned VB6 programmer and was wonder what should I use to develop these apps. I know that eVB is free but have heard it is dying and has problems. I have VB.Net standard but It does not appear to have any tools for Pocket PC development. First, is eVB a bad choice, and, what version of VB.net (or visual Studio) would I need to develop for pocket PC's? I have visual studio 6 enterprise. What version of VS.net (should/can) I get at a reasonable upgrade price? Thanks, Kim Dobranski > > Tag: Tab control Tag: 27089

    - Marshal function leaking memory Hi, I hope someone can help with this one. I'm using below function but it is leaking memory although an article on MSDN says it should not leak memory. Dim TopHandle As Integer TopHandle = GetForegroundWindow() Dim buffer() As Byte Dim buffersize As Integer = 250 Dim p As IntPtr = LocalAlloc(&H40, buffersize) GetWindowText(TopHandle, p, buffersize) Dim w As String // Take away below line and the memory leak is gone w = System.Runtime.InteropServices.Marshal.PtrToStringUni(p) LocalFree(p) The marshal function is causing the memory leak. What am I doing wrong? Thanks, Jo. Tag: Tab control Tag: 27088

    - GetTotalMemory, GlobalMemoryStatus Hi Hopefully someone can help me clarify some memory issues and in particular the difference between GetTotalMemory & GlobalMemoryStatus... Apparently GetTotalMemory(false) retrieves the number of bytes currently thought to be allocated. I assume the bytes returned reflect only the managed bytes(objects) that *my* managed code has allocated, is that correct? In other words if I have PInvoke calls that allocate memory that would not be included, right? Is there anything else GetTotalMemory excludes that one would assume is included? I observe a large difference between what GetTotalMemory returns and what GlobalMemoryStatus reports (taking in account the memory used by the system. No other apps running). I am guessing this is because the GlobalMemoryStatus includes the JITed code as used memory whereas GetTotalMemory doesn't; is that correct? Still the discrepancy is large so there must be other factors that I am not aware of... For example when GetTotalMemory returns 446KB GlobalMemoryStatus (or indeed the memory control panel or even the remote system info from eVC) shows 9072KB. What extra bytes is it including? It seems even the simplest CF app (8KB exe) consumes over 1MB of memory. Is that right or is there some flaw in my approach? Also GC.Collect affect the results of GetTotalMemory but not the results of GlobalMemoryStatus... is that in line with your observations? Note that when the above results are observed, I then leave the unit/app running for at least 1 hour (in idle mode) and the results remain the same... I have also used the slider to effectively force a memory load of over 95%... Cheers Daniel Tag: Tab control Tag: 27086

    - OOM component, OutOfMemoryException Hi I have been experiencing the OOM dialog that CE throws up so I am trying to diagnose where the leak in my app is (assuming there is one)... The dialog pops up with the caption "Program Memory is Low". Then there are options to close a form down or "Convert some Storage Memory to Program Memory...". I understand this is the OOM component... I would like to handle this situation in my code rather than have the OS do it not only because that dialog actually goes beyond our (240x320) screen but because I would rather reset the unit (or restart the app) if a GC.Collect doesn't help at that point... So the questions are: 1. Has anybody else done this before? I understand that I will have remove the OOM component and then call SetOOMEvent (just changing the registry values had no effect)... I think I'll pass it a handle and 0s for the remaining 4 values.. Anybody see a problem with that? 2. Shouldn't I get an OutOfMemoryException when the low memory condition occurs? Replicating a low memory condition (using the memory slider) always results in the OOM dialog coming up and never an OutOfMemoryException. Could it be a case of the dialog popping up before the GC has a chance to collect the garbage? Cheers Daniel PS This is with CF 1.0 SP2 on own CE 4.2-based device Tag: Tab control Tag: 27085

    - Printing Invoices I've gone through every post I could find and have found 3 solutions, but none of them are working for me. The situation: My app will be used by field technicians to print service invoices out in the field. They will be printing to HP printers via IrDA. The problem is that I can't format and print my invoices. The first solution I found was FieldSoftware's PrinterCE tool, but my employer is a small pest control business and can't afford to buy this for me. It would work perfectly, as I could format the invoices properly, but it's not an option for me. The second solution I read about was creating an HTML document and somehow printing that. This would be great if someone could explain to me how I could print an HTML file. I found the HP Mobile Printer SDK, but it doesn't support printing HTML files. It only supports a handful of text/picture files and I don't know if I could even convert my HTML file to a format that the printer SDK could even use. Any ideas on this? The third solutions seems to be using PInvoke. I've never used it before, but I poked around have a general idea of how it works. It sounds like I'm supposed to use some methods in coredll.dll, but I can't figure out which ones. I can't even figure out what methods are in that file. Someone mentioned "dumpbin /all coredll.dll", but when I ran that I got an error that said I was missing mspdb71.dll, which Google knows nothing about. Is there a site somewhere that lists the members I could PInvoke in that file? Is that the file I'm even supposed to be using? Any help would be much appreciated. I've been spinning my wheels for several days now, going through forums and websites. Thanks in advance, Deadly_Bait Tag: Tab control Tag: 27083

    - Exceptions in exceptions in webservices Hey Cryptic subject, eh... In my webservice im doing code like this: try { //Some code that might generate an exception } catch { //Im logging all errors to a file here } On my PDA im doing code like this: try { //Calling my webservice here } catch { if the webservice fails the user gets a message and i can see the error in the log file } Now, my question is. What happens if writing to my logfile fails? What i would like to happen is that i can tell the user to contact me, so that i can take action on the issues. Since the logfile is my only way to see that errors has been generated its very important that i can see the errors. So i have tried to make a try catch block inside the catch in the webservice. That should raise an exception if writing to the log file fails. But even though it probably does that, all i can see on my PDA is the same error as when i just wrote to the logfile without using a try catch for that. Am i misunderstanding this?? -- Jimmy Tag: Tab control Tag: 27069

    - RAS.Dial + WebRequest -> Error? Dear NG, i need to make a RAS.Dial in my App. But due to some circumstances i also need to make a WebRequest to a page. If i call Ras.Dial and then make the WebRequest, the System tries to make another connection on its own and gives me an Error, saying that it cant establish a connection. If i put the Timeout to 5 Seconds the WebRequest also throws a timeout-exception. I wrote a small app which reproduces this issue and which i put at the end of this post. Please remember to fill in your custom connection, user and passwort for the RAS.Dial. If anyone knows the problem and can tell me how to solve it, i will appreciate it.

    - how to create a VB/C# CF helper dll Hi, I program in eVB 3.0 and Pocket PowerBuilder for WinCE devices. I started looking into the CF using VB/C# recently in order to create some a DLL that does some simple things like memory available, battery status, get handheld name, uniques ID, ... I have found many example of how to implement these APIs and have a working VB.net executable. What I would like to do is create a class library (DLL) that would expose these methods to another application. My problem is I don't think I'm doing it properly. I have created a VB.net Class library project, (see below) which compiles fine, and I have created public functions for a couple methods I want exposed. Ideally, I would like to access these methods like a standard API call. I would declare the function as coming from this DLL I wrote with a return of a particalur type. Can this be done?

    - class to class Hey I was under the impression that it was possible to return an object of a class from a webservice, and then assign it to an instance of the same object on the PDA program receiving the returned object. Example webservice: namespace WS { [WebService(Namespace=http://whatever)] public class WS : System.Web.Services.WebService { retClass retObj = new retClass(); ... ... ... [WebMethod] public retClass Get_Value(){ ... ... ... retObj.retInt = some value; retObj.retString = "some string" retObj.retDS = some dataset; return retObj; } } public class retClass { public int retInt = 0; public string retString = ""; public DataSet retDS = null; } } And the following is my PDA app.: { public class retClass { public int retInt = 0; public string retString = ""; public DataSet retDS = null; } mainclass{ WS ws = new WS(); retClass retObj = new retClass(); retObj = ws.Get_Value(); //This is where VS tells me that it cant convert ws.Get_Value() into a retObj } } Well i left some code out (guess you allready figured out). Ok, what is going wrong? Why cant i do this? -- Jimmy Tag: Tab control Tag: 27044

    - Enable SIP without having a mainmenu or taskbar Hi @ all, after reading a lot of stuff, I couldn't find a solution. I have an application, written in VB.NET, which needs to run in kiosk mode without any tasbar, main menu or something else. As it is an application, where data has to be entered, I really need a small keyboard, which could be activated if needed. Does anybody know how to split the SIP from being dependent on a menu/taskbar? Does anybody know another possible solution like a keyboard-control?

And is there some limit in the number of rows in a CE database ??? Because i'm trying to read in a database which has 2 tables. One with 4 columns and like 80 rows, the second has 4 columns and about 39000 rows. When I try to fill the databse I get the following error : System.Data.SqlServerCe.SqlCeError : The data is truncated so I guess or that i'm using too big of a number to be contained in the int field, or I'm using too big of a string in the nvarchar field ??? So what is bigger than int in SQL ??? Thought I saw bigint somewhere but I just cant seem to find it :( thanx... Tag: Tab control Tag: 27031

    - General access to Windows Directories on PPC, C# Hi all, During installation of my PPC app (C#), I install a custom font file (TTF) into the \Windows\Fonts directory on the PPC. This is achieved in the .INF file by specifying its location as %CE15%, a macro string. However, in my C# code, I hard-code this path in one of my global strings, as follows: public static string strFontPath = @"\Windows\Fonts\"; I have now found that international versions of Windows do not use the English name "Fonts" as a folder name. Are there macro-like strings in C# that I can use to access the specific Font folder without the need to hard-code it? Or is there a more "international" standard of accessing these folders without knowing the local language? In fact, this question will apply to all sub-folders under \Windows. I understand that the word "Windows" is used as a folder for all languages but I am not 100% sure of this. Regards, Neville Lang Tag: Tab control Tag: 27024

    - Bridge between eVC++ and .NET Framework I'm working first time in eVC++ while my partner is working in C# .NET. He created some methods to access SQL CE Server, and I wrote an Today Screen Application. I need to call those methods, to get data to show in Today Screen Item. I saw some articles talking about COM interop, but always between .NET and Visual C++, not embedded VC++. My teacher said, maybe the only way is using sockets. It is possible to do that? If it is, how. Or, if is possible more than one, how (or what) is the easiest way to do that. My project ends at 28th May, so thats why the hurry.

    - Compression, Can It Be Done? hi, What i'm doing is grabbing the image from a picturebox, which is getting stored into a memory stream. The problem with getting the bitmap data this way is i can only get 16bit and 24bit images. This would be fine but i then want to send this data over the internet to a remote pc. Which is all do-able except the size of the bitmap data is around 57k!!! which is far far too big! So wot i need to do is compress the data. However i've searched around for the examples of how to do is and i'm not too optimistic that it can be done! The only other info you need to know is that i'm programming in VB.Net CF Thanks, Craig.

    - String or Integer? Hi Im a relative newbie to the .NET CF and am writing in VB.NET I have a class (class A) that could hold a potential of 15 different classes in its "data" member field. I have added a field called "dataobjectname" which I set whenever I add the data member. Whenever I look to call the "convertToBytes" of on class A I read the "dataobjectname" and cast the object accordingly and call its "convertToBytes" member method I looking to optimise my code and thought that Id replace the field "String - dataobjectname" with "Int16 - dataobjectname" and use an enumeration list" before casting. Will this reduce the amount of memory used in my application? Will there be performance improvements E. Class .. .. Dim data As Object ' Can hold any 1 of 15 different objects Dim dataobjectname As String Im open to suggesting in case anyone knows of how to do away with the dataobjectname field altogether so that I save even more memory whilst my app is running Tag: Tab control Tag: 26941

This is a known issue wioth the tab control. The workaround is to properly
order the tabs in the ctor after the call to InitializeComponent
