Asked On May 12, 2003 11:05 PM

Hi, I can't compile my existing VB.NET programs or write new ones because I get this error ervery time: 'System.ArithmeticException' occurred in system.drawing.dll. To duplicate this problem, I create a new VB.NET project with a single form. If the is blank (i.e, has no controls or menus) then it would compile and run, but as soon as I put any control or menu on the form, I would get the above error when i compile or run it. Can anyone help me? Thank you.

So this problem is not specific to Syncfusion controls? If its a general problem, you may have to re-install the .NET framework.

What's the setup of your computer? - I have exactly the same problem, (and have not been able to find a solution). My PC is a dual proc Xeon 2.2 Regards Jeremy

Try doing a Google search for "'System.ArithmeticException' occurred in system.drawing.dll". Seems like other programmers also ran into this issue (see the groups). There is also a KB article: http://support.microsoft.com/support/kb/articles/q326/2/19.asp Q326219 BUG: Exception Error When You Change FPU in Managed Application Not sure if this related ... Maybe one these links help: http://groups.google.com/groups?q=%27System.ArithmeticException%27+occurred+in+system.drawing.dll&hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=e86bf36a.0210170550.338b0c0e%40posting.google.com&rnum=1 http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&threadm=aZQb510TCHA.2132%40cpmsftngxa08&rnum=11&prev=/groups%3Fq%3D%27System.ArithmeticException%27%2Boccurred%2Bin%2Bsystem.drawing.dll%26hl%3Den%26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8%26start%3D10%26sa%3DN Other than this, no idea what could cause this.

Stefan Any chance of translating the code on the Microsoft KB to VB? I experience this problem with all controls - in my own application where I'm using the native Msoft controls, I can trap for the error and just ignore it. You had this problem in version 1.5.2 - in 1.6.2 the GridDataBoundGrid now traps the error - however most of the other controls do not. I've created a number of DirectTrac reports relating to this, but to no effect. The simplest solution is to trap anything that initializes a system.font - I would prefer the control not functioning rather than crashing the application. Regards Jeremy

Did you ever try reinstalling the whole system? Or try installing a 2nd os on the same system, just the bare OS and then the .NET Framework. And then see if the problem happens after you install a specific application. But I will also make sure we'll add try/exception pairs whenever we allocate fonts (maybe a global utility fn that does that). But you might still get errors with the .NET controls themselves, e.g. LinkLabel also does not allocate fonts with try/catch. I looked through our database. We had once a customer report a similar problem with allocating font and he said it was because of a faulty ODBC driver he had, some kind of buffer overrun. Stefan

Stefan I've had VS Studio installed on two machines both dual proc - one d/p Xeon and one d/p P3 400, under Win 2000 as well as XP Professional. I've never installed it on a single proc machine. In each case I've had the same problem. I had some correspondence with someone from Microsoft on their newsgroup, who gave completely incomprehencible instructions to get around the problem. Essentially he gave the same info as the chap on the link you provided above. Further he suggested that at some point I was initializing some kind of access to printing under NET which I wasn't (and still not), implying that this was the probable cause of the problem. I've looked at the BIOS on my machine to see if there is some way to turn of FPU operations, but to be honest I don't know what I'm looking for. I attach a list of running procs on my machine (none of which seem to be particularly likely to cause this problem). On a side note, I occasionaly have a situation where Windows goes completely bananas - all the text in all the windows (Word, Excel, Explorer etc) start moving up and down at at a frantic rate. This used to happen with VB 6.0 on Win 2000 as well, and only happens when VS Studio is running - this might happen once a month - rebooting solves this problem. Not sure if this is related in any way. The arithmetic error problem is also not consistent. Sometimes its really bad, sometimes I don't get it at all. I really can't pin down under what circumstances its particularly bad. However, its interesting to note that your controls without the try/catch will fail 100% of the time, while the native LinkLabel might fail 15% of the time. Anyway, thanks for taking the time out to try helping me with this problem. I'd also like to take this opportunity to say your suite (minor problems aside) is absolutely marvellous. I have succeeded in completely updating one major application, and am in the process of updating a second to take advantage of your controls. I have other suites (Infragistics and Developer Express) but have never managed to get to grips with them - your is by far and away the most useful and customizable suite I've come across, and the support here is exceptional. Assuming that you manage to fix the arithmetic exception problem, would you consider creating two other controls???? 1. A checkbox control that has a transparent background for the text with XP Themes enabled (the Miscrosoft version looks horrid on your gradient panel) 2. A way of getting the XPComboBarItem to work properly with an external datasource, and the combo to work like the DataGridComboBox??

Jeremy, we'll have wrapped all new Font calls with try/catch calls and that should be in the next time we build. I'll forward your feature requests to the tools team. Here is one more suggestion. Can you try the following code instead of the code suggested in the MSKB article: [C#] [DllImport("msvcr70.dll", CallingConvention = CallingConvention.Cdecl)] public static extern int _controlfp(int n, int mask); private void Form1_Load(object sender, System.EventArgs e) { const int _RC_NEAR = 0; const int _PC_53 = 0x00010000; const int _EM_INVALID = 0x00000010; const int _EM_ZERODIVIDE = 0x00000008; const int _EM_OVERFLOW = 0x00000004; const int _EM_UNDERFLOW = 0x00000002; const int _EM_INEXACT = 0x00000001; const int _EM_DENORMAL = 0x00080000; const int _CW_DEFAULT = _RC_NEAR + _PC_53 + _EM_INVALID + _EM_ZERODIVIDE + _EM_OVERFLOW + _EM_UNDERFLOW + _EM_INEXACT + _EM_DENORMAL; _controlfp(_CW_DEFAULT, 0xfffff);; } [VB] _ Public Shared Function _controlfp(n As Integer, mask As Integer) As Integer Private Sub Form1_Load(sender As Object, e As System.EventArgs) Const _RC_NEAR As Integer = 0 Const _PC_53 As Integer = &H10000 Const _EM_INVALID As Integer = &H10 Const _EM_ZERODIVIDE As Integer = &H8 Const _EM_OVERFLOW As Integer = &H4 Const _EM_UNDERFLOW As Integer = &H2 Const _EM_INEXACT As Integer = &H1 Const _EM_DENORMAL As Integer = &H80000 Const _CW_DEFAULT As Integer = _RC_NEAR + _PC_53 + _EM_INVALID + _EM_ZERODIVIDE + _EM_OVERFLOW + _EM_UNDERFLOW + _EM_INEXACT + _EM_DENORMAL _controlfp(_CW_DEFAULT, &HFFFFF) End Sub 'Form1_Load Stefan

Try adding Main method and put the code there. Then in your project settings, set the StartUp to this Main...

You can find these methods in C:\Program Files\Microsoft Visual Studio .NET\Vc7\include\float.h My guess is _statusfp. Too bad that didn't help either. I am out of ideas. But we'll wrap the "new Font" calls. Stefan
