Please show the actual code that is not working and explain in detail. No one can guess what your code does.

Instead of disabling the menu-item, I'd recommend not creating it in the first place.

Try creating a variable in the login form, when any of them logs in assign a value to that variable. Note: the value assigned should be different depending on who logged in. E.g (variable_name = 1..when admin logs in, variable_name = 2..when user logs in ). On the load event of the main form use an if statement to check the value of that variable. Depending on the value of the variable disable the menustrip item using the its name. Example when a normal user logs in
If(variable_name=1)
{
Menustripitem_name.enable=false;
}
Remember to declare the variables for validation as static variables in the login form so as to access it in the mainform.
Hope that works

Thanks.
I also solve this problem but my procedure is different first i MDI Parent form menustrip itme property change the modifier it declared public and then i access this menu strip in other form like login form.
step:1
menustripitem property = public
step:2
creating an object the login form
step:3
object.menustripitem.Enabled = false;
it working properly

you also realise that you can merge menu's from the child forms into the parent container?

check it userwise
if(user =="admin"){
menu.IsEnable=true;
}
else {menu.IsEnable=false;}
something like this

Try making a Boolean variable.
On login, the app must determine if the logged in user is admin or not.
Then, set the appropriate values.
On login:
If user is admin: adminbool = true
else
adminbool = false
On form_load
If(adminbool=false)
{
Menustripitem_name.enable=false;
}
else
{
Menustripitem_name.enable=true;
}
You get the idea, right?

? A big code dump. So what? What's the problem?

Hi,
We have a Windows Forms project with quite a few flatstyle buttons.
When we disable the buttons, the colors of the buttons are changed automatically 
Is it possible to override this somehow, so we can control the colors ourselves?
Thanks,
Karl
|
|
|
|
|
You could create your own buttons, the simplest way is to inherit from Button and override some functions:
public class BernieButton : Button
{
protected override void OnEnabledChanged(EventArgs e)
{
base.OnEnabledChanged(e);
....
}
}
|
|
|
|
|
Yeah, that's the expected behavior. It's the standard notification to the user that the button will no longer work in the current situation.
Why would you want to change this?? If you don't change the color, the user will wonder what's wrong with your app because they think they're clicking on an active button and nothing is happening!
|
|
|
|
|
In fact the BackColor of control doesn't change and only ForeColor and BorderColor change.
Set FlatStyle to Flat, Set a non system BorderColor in FlatAppearance, Set a non system BackColor and you will see background and border will not change.
Only ForeColor changes to show difference of enabled and disabled button.

i create control and this control derived from gridview control.then i add 2 column in constructor like this :
InitializeComponent();
this.AutoGenerateColumns = false;
DataGridViewCheckBoxColumn cb = new DataGridViewCheckBoxColumn();
cb.HeaderText = "";
cb.Name = "dgvcSelect";
this.Columns.Add(cb);
DataGridViewTextBoxColumn tb = new DataGridViewTextBoxColumn();
tb.Name = "dgvcRowNumber";
tb.HeaderText = "ردیف";
but when i run my program 4 column generate for me.where is the problem?
please help me

Need a bit more of the code the way this code looks is that you have created two columns but can't see enough to know what is happening.
Please post the entire scope of the problem so we can help.

Hi everybody,
I'm trying to bind a class variable to a textbox.
the data class looks like:
<pre lang="c#">
public class route
{
public string name { get; set; }
public int adress { get; set; }
public route()
{
name = "";
adress = 0;
}
}
public class adr
{
public int index { get; set; }
public route r1 { get; set; }
public route r2 { get; set; }
public adr()
{
index = 0;
r1 = new route();
r2 = new route();
}
}
public class para
{
public int i1 { get; set; }
public int i2 { get; set; }
}
public class adrData
{
public string label { get; set; }
public adr ad { get; set; }
public para pa { get; set; }
}
When I try to bind f.e. ad.r1.name to a textbox text via designer, it offers only label, ad and pa for binding.
What am I missing here?
Thnx adv for your answers.

What type is "ad.r1.name"? As far as I can see from your code, there's only one "name" property, and that's a string, whereas the bindin-options imply that "name" contains an adrData?

its a tree structure:
the string name is an element of class route,
route r1 is an element of class adr,
adr ad is an element of class adrData.
|
|
|
|
|
First, I think you need to add a constructor to 'adrData:
public class adrData
{
public string label { get; set; }
public adr ad { get; set; }
public para pa { get; set; }
// ctor
public adrData()
{
label = "";
ad = new adr();
pa = new para();
}
}Then, in code, you can do something like this:
adrData newAdrData = new adrData();
newAdrData.ad.r1.name = "Route Name #1";
textBox1.DataBindings.Add("Text", newAdrData, "ad.r1.name");To bind to a specific instance of 'adrData. Unless you create a new instance of 'ad, within 'adrData, then you never initialize the 'routes: because only creating a new instance of 'adr will initialize the 'routes.

Hi ,
At the moment I'm developing an Windows Form application and looking for a logger. I have seen log4c++ and boost.log, but both loggers won't work because some code isn't compatible with /clr code. Does somebody has a logger which is compatible with Windows forms?
