CommandText is placed in the resx file

I have the following class defined:

[DesignTimeVisible(false),
ToolboxItem(false),
Designer("Agrovision.Data.Design.CommandDesigner, Agrovision.Data.Design,
Version=3.0.3.0, Culture=neutral, PublicKeyToken=27bbda75f3eecde7",
typeof(IDesigner))]
public class CommandClass: Component
{
private string FCommandText;
private string FConnectionName;
private string FTableName;
[DefaultValue(null),
Editor("Agrovision.Data.Design.CommandTextEditor,
Agrovision.Data.Design, Version=3.0.3.0, Culture=neutral,
PublicKeyToken=27bbda75f3eecde7", typeof(UITypeEditor))]
public string CommandText
{
get
{
return FCommandText;
}
set
{
if (FCommandText != value)
{
if (value == null || value.Trim() == String.Empty)
FCommandText = null;
else
FCommandText = value;
}
}
}

[DefaultValue(null),
Editor("Agrovision.Data.Design.ConnectionNameEditor,
Agrovision.Data.Design, Version=3.0.3.0, Culture=neutral,
PublicKeyToken=27bbda75f3eecde7", typeof(UITypeEditor))]
public string ConnectionName
{
get
{
return FConnectionName;
}
set
{
if (FConnectionName != value)
{
if (value == null || value.Trim() == String.Empty)
FConnectionName = null;
else
FConnectionName = value;
}
}
}
[DefaultValue(null)]
public string TableName
{
get
{
return FTableName;
}
set
{
if (FTableName != value)
{
//Check is FTableName is unique
if (value == null || value.Trim() == String.Empty)
FTableName = null;
else
{
FTableName = value;
}
}
}
}
}

When I place this component on a form which has the localizeble property set
to true, the value of the CommandText property is saved to the resx file,
while the values of the ConnectionName and TableName properties are saved in
the Designer.cs file.

What's the reason for this behaviour and how can I prevent that the value of
the CommandText is saved in the resx, because it's not localizable, ofcours.
 
Hello,

The main difference between the "CommandText" and "ConnectionName" is their
Editor attributes:

Agrovision.Data.Design.CommandTextEditor
Agrovision.Data.Design.ConnectionNameEditor

Have you check the implemnents of these two Editors, to see if they cause
the problem? Or you may post their code here so that we can build a similar
component and test to see if we can reproduce the problem?

Sincerely,

Luke Zhang

Hello,

Thank you for the information. Because lacking of other parts of your code,
like, definition of CommandClass, I cannot build a similiar sample on my
side. Anyway, when you run the code in VS.NET, have you check the "value"
passed into:
public override object
EditValue(System.ComponentModel.ITypeDescriptorContext context,
System.IServiceProvider provider, object value)

Is actual a string value?

If it was possible, please email you a sample which can reproduce the issue
completely, I may take a look at it on my side, to see what happened. (To
get my actual email, please remove "online") If we can reproduce the
problem, it will be a little easy to found its root cause.

Sincerely,

Luke Zhang

Hello,

I have examined it a little further. It appears that the commandtext is
saved in the resource when it's length is more the 200 characters. This not
only applies to the commandtext property, but to all string properties, e.g.
the Label.Text. It's saved to the resouce even if the localizable property of
the form, usercontrol or component is false. When you decrease the length of
the string, the property is removed from the resource file and placed in the
Designer.cs file.
So it seems you have no control over the fact if a lengthy string is saved
in the resource or not. In the case of the commandtext that's very
dangerouse, because a translator of the resource could change the commandtext
to a wrong statement.

Regards, Jaap

Hello,

But how can I prevent long strings from being saved in the resource file?
I don't want them in my resource, because they are not localizable!
