Go to Project -> Add Class. Name your class Variables. Here is an example:

using System;
using System.Collections.Generic;
using System.Text;

namespace YourNamespaceName
{
class Variables
{
public static string var = "";
}
}

then to call on your variable from any code just access it like: Variables.var

Make a static variable in the main form, then you can access it from any form.

If you want to be stricter about object orientation, make a private static variable, and a public static property to access it.

Static class with static member and memory allocation

Herhighness6-Sep-06 6:36

Hi,

I have a static class, and it contains a private static member for resource management.

static class ConnectionManager
{
private static ResourceManager resmgr = new ResourceManager("myApplication.stringresources", Assembly.GetExecutingAssembly());

----------

--------

''''''''''''

}
initializing a static member this way, is this right way to do this?

every time when this class is called, would it reinitialize the static member, creating new memory allocation?
or would I have a single memory allocation alloted the first time class is refereneced?

Thanks,

herhighness

Yes, it is a right way.

The initialization of a static variable would be executed only once. You'll have the single memory allocated the first time class is refereneced.

Best,
Jun

Hi to all,

does any one knows how to resolve this problem

System.Ressources.MissingManifestRessourceException : Impossible to find the appropriate ressources for the specified culture of you assembly.

in fact, i have an image liste on a user control, and that's what is causing the problem, because when i delete the image list from the user control than i have no problem. if i try to put a new image liste, the message reappear again.

best regards and thanks in advance

Help a noob C++ user with C# (union and bitfields)

NYTSX6-Sep-06 5:36

6-Sep-06 5:36

Hi I am trying to learn C# right now on the fly. I want to know if there is a way to implement a bitfield in C# as I would in C++

In C++ I would implement something like this:

typedef struct
{
  union
  {
	unsigned short Value;
	struct
	{
		unsigned short Test1_usec       : 7;
		unsigned short spare1           : 1;
		unsigned short Test1Pass	: 1;
		unsigned short spare2		: 2;
		unsigned short Test1Verify	: 5;
	}Bits;
   }Word1;
   
   union
   {
        unsigned short Value;
        struct
        {
		unsigned short word2Data1       : 12;
		unsigned short spare1           : 4;
	}Bits;
   }Word2;
} ARecvdMessage

what would the C# equivalent be for this struct?

Thanks.

Can you help with the code that will mimic the C++ code that I had posted? I read the articles but it doesn't behave as I would suspect it would. I am trying to read data from a serial port directly into this would be struct.

Not a good idea since the code involves unmanaged memory that might lead to trouble if you are not familiar the issues. However this blog entry[^] should send you well on your way towards a solution.

Good luck

Using propertygrids

Hello!

I am using a propertygrid such as the one used in the following examples:

http://www.codeproject.com/cs/miscctrl/bending_property.asp[^]

http://www.codeproject.com/dotnet/ObjectWrapper.asp[^]

However I was wondering if anyone knows if it is possibile to start my application without having all the main properties expanded such as when one clicks on the minus signs?

Best regards,

CS0029: Cannot Implicitly Convert Type...

This is probably something simple for those in "the know" but I'm not
part of this exclusive group. Blush | :O

So any help would be very appreciated.

Any idea why this code:

public override void LoadData()<br />
{<br />
    // Call base.LoadData()<br />
    base.LoadData();<br />
    if (!this.Page.IsPostBack) <br />
    {<br />
        ArrayList list;<br />
        if ((DataSource == null))<br />
        {<br />
            list = new ArrayList();<br />
        }<br />
        else<br />
        {<br />
            list = new ArrayList(this.DataSource);        <br />
<br />
        }<br />
        int i;<br />
        for (i = 0; i < 50; i++)<br />
        {<br />
            // To insert rows at the end of the table control<br />
            list.Add(new LineScheduleRecord());  <br />
<br />
            // To insert rows at the top of the table control<br />
            // list.Insert(i, new LineScheduleRecord());               <br />
        }                  <br />
        this.DataSource = (LineScheduleRecord[])(list.ToArray(typeof(LineScheduleRecord)));<br />
    }<br />
}

Would produce this error:
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0029: Cannot implicitly convert type 'LINESCHEDULER.Business.LineScheduleRecord[]' to 'LINESCHEDULER.Business.LineScheduleAdminRecord[]'

it would appear that the error is in the error

Cannot implicitly convert type 'LINESCHEDULER.Business.LineScheduleRecord[]' to 'LINESCHEDULER.Business.LineScheduleAdminRecord[]'

the cast is wrong. perhaps you should have something like this:

this.DataSource = (LineScheduleAdminRecord[])(list.ToArray(typeof(LineScheduleRecord)));

What's the type of this.DataSource? If it's LineScheduleAdminRecord[], then it looks like it's a cast problem. Of course, that's assuming list has LineScheduleAdminRecord instances.

Running .net application as both windows and console mode. [modified]

Hi All

I am writing a .net windows app that should also run from command line. I am not sure what is the best way to set such a project.

I intend to create a windows project and on the Sub Main rotine check if any arguments are passed. If not run a form.

Public Shared Sub Main(ByVal Params() As String)<br />
  If Params.Length = 0 Then<br />
    'run windows mode<br />
    Application.Run(frmMain)<br />
  else<br />
    'run console application<br />
    some code<br />
  End If<br />
End Sub

Would this be the best way or is there any standard way of doing this ?

Many Thanks
Mustafa

Probably:

public static void Main(string[] args)
{
    if (args.Length == 0)
    {
        Application.Run(new MainForm());
    }
    else
    {
        // Run as a console application here
    }
}
