Are you aware of any spreadsheet like application (incl. Grids) that could be run on .Net Micro Framework?
Appreciate your information.
Thanks,
Srik

Thanks Jinal, for referring a very good site.
btw, if you come across any of the KB related to a custom made lib that renders a spread sheet like UI using micro framework, pl pass on. I appreciate all your help.

thanx to the replies for my previous post i registered a dll using gacutil.exe , but now when i'm trying to use it in a project i tried to add it as a reference , but it is not displayed in the dialog box, but that dll is shown in the "c:\windows\assembly", any idea why this happens.
and need another clarification , when we use drag and drop we put the dll in the
"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727" for version 2.0. but when we use gacutil.exe the dll is in the "c:\windows\assembly", can anyone explain what is the difference of these two folders and what is the folder called "gac". as i read gac is the folder "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727".

GAC is Global Assembly Cache, http://msdn.microsoft.com/en-us/library/yf1d93sz(VS.71).aspx[^].
I'm trying to remain positive and encouraging, however if you don't know this, or at least know enough to Google it, then you shouldn't be doing .NET development.

The listed 'GAC' assemblies shown in the add references is not sourced by the GAC. Visual Studio holds various reference paths in the registry that point to the physical, non-GAC location of the assembly. eg. "C:\Windows\Microsoft.NET\Framework\v2.0.50727" which holds the 2.0 assemblies.
While you can add your path to the registry it would be simpler to just browse to the dll an add the reference.

thanx . i thought vs 2005 get all the dll which only from GACs

int n = int.Parse(CustomerID[CustomerID.Length - 1].CustomerID.Substring(4, 3)) + 1;
i try this to generate customer ID but kept telling me the is clash with surburbID becouse i linked surburb in customer table

Dear Kolisa,
have you tried something like that:
int currentMax = CustomerID.Max(customer => int.Parse(CustomerID.Substring(4, 3)))+1;
I assume you use c# as your choosen language in version 3.x. If not, pls specifiy your problem in more detail. Besides, i suggest to give your variables more distinguished names. Have an array with name CustomerID of type CustomerID is a little bit confusing. Also int.Parse on a substring without null checks or length checks is quite dangerous.
Regards
Jens

You have given very little context. What is surburbID? I assume a foreign key. What does your data structure like? How are you assigning the id? We can't read your mind and we're not working on the same project with you.

i wrote this code to retrieve size from the database
private void grpSize_Enter(object sender, EventArgs e)
{
string size = "";
if (rdbLrg.Checked)
{
size = "Large";
}
if (rdbReg.Checked)
{
size = "Reg";
}
if (rdbSupa.Checked)
{
size = "Supa";
}
i am using this to pass it to the next from
frmOrderDetails order = new frmOrderDetails(lstItems.SelectedValue.ToString(),rdbSupa.Checked.ToString());
order.Show()
but what it does shows me true when i click the size i want and show false when i click other button i want it to retrieve the size i putted on the database
|

can you post code where you retrieve size from database
based on the selection ??

Why are you passing the ToString of a boolean? That is asking for trouble.
If all the radio buttons are in the same group you should add else before the 2nd and 3rd if statements. No reason to check for all 3 every time.
I also don't understand why you wouldn't pass size to your second form.

Hi All,

This exact same code works fine on one of our other machines. Is there some .NET setting that needs to be added/modified on the machine that is recieving this error?
Any help would be greatly appreciated.
Thanks,
Mel

Hi Mark,
Thank you for your reply. I added the AllowPartiallyTrustedCallers attribute to the assembly of the application but this didn't solve the issue.
Let me given more imformation. I have a webApplication that has the dll file (let's call it App1.dll) of a windows application in it's bin folder, which I have also added as a reference. App1.dll is where AUser() is created from and in turn AUser.VerifyCredentials() is called in line 37, which is giving the error.
I added the AllowPartiallyTrustedCallers attribute to the assemblyinfo.cs file of the App1 project and then copied the new App1.dll file to my webApp's bin file again and re-added the reference.
Am I missing a step? Is there something else I need to carryout?
Thanks,
Mel

That could be the key. Not all code can be used in a web application because of security restrictions. What are you trying to use? It could be making a link demand to some API method, directly or indirectly, that is not allowed in a web environment.

This same code works fine locally on my machine it's when I try and run it from our server.
I guess there is no need for me to run it like this on the server, maybe it will work fine once I publish the webSite in VS.
Thanks for your reply.

We have some .Net 2.0 apps, a 3.5 app, and plan to do 4.0 in the future.
Do I need to install all 3 runtimes, or is there a super-version?
4.0 looks really small compared to 3.5, and I think it may only contain stuff specific to 4.
I need an app that will automatically deliver a new BBBBBBBBaBB (beautiful blonde bimbo brandishing bountiful bobbing bare breasts and bodacious butt) every day.

2.0, 3.0 and 3.5 use the same 2.0 CLR. 3.0 and 3.5 are just a bunch of extensions on top of 2.0.
4.0 is a completely new CLR. There are 2 versions of the .NET Framework now. There is the full, heavyweight version that everyone is used to seeing and now there is a Client Profile version which is much lighter in weight and only includes the components that are used the most across the majority of applications.
You can read more about it, and what's included and what's not, here[^].

You need all the three runtimes installed (unless you specify the runtime using the runtime tag in your application configuration file).
.Net 4 is actually a big change over the others as a new version of the CLR has been released along with it.

i tried to install a .dll file to gac using gacutil.exe. i did it successfully , but i don't see that dll
in the gac folder.i want to know whether it copied to gac from the source when we install it using gacutil, if not what happens.

For GAC Commands and other details you can check following links.
http://msdn.microsoft.com/en-us/library/ex0ss12c%28VS.80%29.aspx[^]
You can confirm whether your assembly is really added to GAC or not by traversing following path
which opens GAC Space where all the assemblies (added to GAC) reside.
%WINDIR%\assembly
You can also add your assembly to GAC by directly drag your assembly and drop it in GAC Space.
Hope this will help!

Make sure your dll is strongly named before trying to put it in the GAC.

thank you for your help, i found my dll in the assembly.
