how to retrieve the type of each field? I mean, I would like to know that, for example, 's' is a string
further questions - is it possible to retrieve also information about arguments that funcion takes and the return type?
|
|
|
|
|
Type type = typeof(A);<br />
MemberInfo[] mis = type.GetMembers();<br />
foreach (MemberInfo mi in mis)<br />
{ <br />
System.Diagnostics.Debug.WriteLine(mi.Name + ": " + mi.MemberType.ToString());<br />
}
|
|
|
|
|
it doesnt work - I tried and MemberType gives exactly the same as MemberType.ToString() - it gives only general info (method, field, etc) and I want detailed information (string, int, char, etc)

You want ReflectedType. All your questions can be answered by MSDN[^] though.

Hi all,
I've built a Windows Service wich accepts arguments in the main function so I can execute the exe like <code>MyWindowsServ.exe –install</code>.
I can install the service, I can run it, and everything runs ok.
Now, what I wanted to do was to install the service so when it starts it can take some arguments as well.
If you look at the COM+ Event System service properties (for instance) in your control panel, you can see that the path to executable is something like this <code>C:\WINDOWS\system32\svchost.exe -k netsvcs</code>
Is there a way I can add these arguments to my ProcessInstaller or ServiceInstaller or something like that?
Thanks,

You can pass startup parameter to windows service but however rather than acceptin arguments in Main Method Windows service accept arguments and handle them in OnStart MethodTo setup startup parameter
Open the windows Services MMC snap-in
Select your Service->Properties-->General
You will find Start Parameters you can write your start parameters in it To add this information when you install windows service you have to write start parameters in registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
start up parameter stored in ImagePath
There are some articles at codeproject about custom installation of Windows service like

I would like to be able to use some old ANSI C functions but have access to them using a new GUI built in C#. Basically I'm trying to take a comsole app and make it windows based. Is there anyway to do this? I have tried adding the reference but, even though the code is compiled under .NET, it doesnt seem to like it. ANy suggestions? Or am I SOL?
Thanks in advance

put your c code in dll and use this dll in your c# code
P/Invoke will help you to do this
look at question titled using c++ dll in this forum page

hi all i´m a little new in c# and i am having problem doing some programming
the question is: implement a method that returns an average of set variavel of arguments in integer type
can anyone help
it is quite simple but not for me
|
|
|
|
|
1. What do you mean by 'set' of arguments?
2. What kind of average? There is several differend kinds of average value...
|
|
|
|
|
So, let's say you have a set of an unknown number of arguments
void Test(params int[] arguments)
{
}
You could compute the average by using something like
int sum = 0;
foreach(int i in arguments)
{
sum += i;
}
int average = sum / arguments.Length;

To pass Variable Parameters to method use params keyword For example
public int GetAverage (params int[] nums)
{
}

Hi All,
This probably really easy for somebody out there but this problem is doing my head in! What i want to do is update a a single cell in a in a datarow of a datagrid with a value from a textbox so i don't have use a query to repopulate the datagrid after a update query.
What i've tried
Updating the DataTable or DataSet from the datagrid before updating with the following code:
1)mydatatable.Rows[lastUpdatedRecord].ItemArray.SetValue(int.Parse(txtVal.Text),0);
2)ds.Tables[0].Columns[0].Table.Rows[lastUpdatedRecord].ItemArray.SetValue(int.Parse(txtVal.Text),0);
and then rebind it to the datagrid.
My problem is that the "ItemArray.SetValue" method doesn't seem to be updating the value when i check it through the step through debugging.
Please help,
Thanks in advance

Dont play with the itemarry. It is handled internally.
mydatatable.Rows[lastUpdatedRecord] = int.Parse(txtVal.Text);
will do the job.

Thank you for your response.
My problem is this:
mydatatable.Rows[lastUpdatedRecord] = "Needs Type DataRow"
DataRow is made up of a array of values, a single value in the array represents a single cell value in the datarow. I just need to update a single cell value in the datarow array.
Is there any other way of updating the datagrid without having to query the database?
Thanks in advance,
|

With just one indexer (lastUpdatedRecord) you reference a single row, but when you use 2 indexers, you can access a single cell:
mydatatable.Rows[lastUpdatedRecord][columnNumber] = newValue;

Is there a CodeParser concrete class to parse C++ code?

There are tools available. Look for programmar in google.

None that I know of. I know for sure that the .NET Framework doesn't have one, but I'm not sure about the availability of 3rd party implementations.

I have successfully called a Fortran dll from unmanaged C++ and now I'm trying this in C#.
This is my attempt:
<br />
class MyClass {<br />
[DllImport(@"square.dll", EntryPoint="aFunc")]<br />
public static extern void aFunc(out int aNum);<br />
public static int Main() {<br />
int aNum=20;<br />
aFunc(out aNum);<br />
Console.WriteLine(aNum);<br />
return 0;<br />
}<br />
}<br />
The dll merely squares the number and sends it back out. The error message is System.DllNotFoundException. I think the reason is that I'm not able to add reference. It keeps saying that it's not a valid .COM or .dll !
Suggestions greatly welcomed.

You need to add the DLL path to the PATH environment variable or you can just copy the DLL in the same folder as your managed assemblies.

I managed to get it to work by putting the .lib and .dll file in bin\Release folder but now I have some new problems.
This works to an extent.
The number goes in OK, and does the calc inside the dll correctly but the new number is not sent back. I tried both "out" and "ref" declarations.
class MyClass<br />
{<br />
[DllImport(@"square.dll", EntryPoint="aFunc")]<br />
<br />
public static extern void aFunc(float aNum);<br />
<br />
public static int Main() <br />
{<br />
float aNum=20.0F;<br />
aFunc(aNum);<br />
Console.WriteLine(aNum);<br />
return 0;<br />
}<br />
}<br />
}
