I have a Resize method that I want called only when the user changes the size of the form. But when I Load that form for the first time I notice that the resize event gets called. Is there some way to prevent this?

I think you're thinking about repainting automatically when the form resizes. There's nothing in CreateParams property (it's actually the protected property Control.ResizeRedraw you're thinking about in this case) or ControlStyles enumeration that controls that.

He doesn't want a fixed-width form, merely to not be notified initially of the resize when the form is loading. You did, however, remind me that it was ControlStyles.ResizeRedraw and the Control.ResizeRedraw property that did match-up, though. I knew there was a pairing there somewhere, just didn't remember off the top of my head.

It is being resized when the form loads. It starts out as a zero-width and zero-height window and then is drawn in the appropriate dimensions, hence the resize.
The solution is simple: use a state variable (recommend private accessibility). It's initially unset (false, for example) and the OnLoad override will set it (true, for example). The OnResize handler (btw - don't handle events from a base class in a derivative class: it's inefficient and gives you less control) will check this state variable. If it's unset, don't call base.OnResize (which will fire the Resize event) and don't call your code that you would normally when a form resizes.

Hi!
yes... and once more...
I now I go: Could somebody please, please, please compile WeifenLuo's DockManager Library in Debug and Release Mode for me? I'm not using visual Studio and I'm having massive problems getting it compiled. Just want to check whether I'm being stupid or my IDE (SD) is...
Source can be found here[^]
Here is my email.
And the last one to go...
Thanks a ton. Seriously.

I just downloaded it and it compiles without any errors for me (VS.NET 2003) in both debug and release.

Sorry, chief. I reread it and I still don't see where I went wrong; I did what the guy asked. I hope your solution below is what he needs.

He said he's not using Visual Studio.

Rename those resources to include the namespace.folder.filename.ext, then just compile with csc

Just to expand on what leppie said, VS.NET will use the project's root namespace + any folder names to construct a default namespace for new source files, or when it compiles resources it will use those names to create a "namespace" for the resource. This is a feature of VS.NEt, however, not the csc.exe command-line compiler - especially since it doesn't even compile .resx files (you have to use resgen.exe for that).

Hi Heath,
I don't seem to get it working. Eventhough I've read the csc and the resgen documentation forward and backward.
Could you (or somebody who's reading this) pls. be so kind an mail me the DLL's (preferably in DEBUG and RELEASE mode, but it's ok if I get only the RELEASE version). I just want to use the library. I'm actually not too much interested in manipulating the source.
Takes you a couple of seconds. Keeps me from getting nuts. 
Thanks again...

You'll never learn anything that way.
For resgen, just include the root namespace of the project plus any folders. Since you don't have VS.NET, then find where the file is used and use the same namespace. Then use resgen.exe like so:
resgen.exe SomeFile.resx SomeNamespace.SomeFile.resources Do that for each ResX file. When you need to compile the source, do something like this:
csc.exe /t:winexe /out:SomeApp.exe /recurse:*.cs /res:SomeNamespace.SomeFile.resources *.cs Or whatever is required.

I write a class(public class MyTableControlA : System.ComponentModel.Component, IExtenderProvider,ISupportInitialize) that have a DataSet and DataAdapter properties.
I have also a MainForm that i drag and drop and initialize DataSet and DataAdapters on it.
I drag and drop myclass on a form, it DataSource property can brow all DataSets on it contain form.
but i want to that myclass can see and use each DataSet and DataAdapset objects that placed on the mainform. i mainform i fill all datasets and i want to use filled datasets in each other form by my class.
notice than i want to do this visually.

Then expose your DataSet and DataAdapter as public or internal properties on your form and access them from your child controls or from other forms:
MainForm form = this.Parent as MainForm;
if (form != null)
{
form.DataAdapter.Fill(form.DataSource);
}If you want to access these from other forms, then make sure those forms have a reference to the form instance that declares the DataSet and DataAdapter and that those fields or properties (properties are recommended since they give you more control via encapsulation) are accessible (public or internal, or protected if a form derives from the form that has those properties or fields).
It's all a simple matter of object-oriented programming. Expose objects with member accessibility that provides other objects access to what they need and denies access to what they shouldn't have.

I have a component that contain a collection of a struct.
I drag and drop this component on a form. than i chang it collection, i want when i close form at design time, my collection content save automatically with form(into form's code or resource).
I use this attribute :"[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]".

As I told you before, you may have to implement your own CodeDomSerializer derivative if the DesignerSerializationVisibilityAttribute doesn't suite your needs.
I also gave you a link to an article that describes such an implementation. I suggest you read it.

I have a class. I can serialize my class by XmlSerializer.
but when i add a DataTable property in the class, XmlSerializer submit an error in this code:
XmlSerializer serializer = new XmlSerializer(typeof(MyCoulumnClollectionClass));
====>>>>
public class SCol
{
[XmlElement(ElementName = "TaxRate")]
public string FieldName
{
get
{
return m_ ;
}
set
{
m_=value ;
}
}
public string DisplayName ;
//````````````````
public DataTable m_columnTable ;
private string m_ ;
[XmlElement]
public string AAAA ;
}
public class MyCoulumnClollectionClass : CollectionBase
{
public SCol this[ int index ]
{
get
{
return( (SCol) List[index] );
}
set
{
List[index] = value;
}
}
public int Add( SCol value )

when i add this property to the class :
public DataTable m_columnTable ;
this error in submit:
An unhandled exception of type 'System.InvalidOperationException' occurred in system.xml.dll
Additional information: There was an error reflecting type 'MyCoulumnClollectionClass'.
error occurein this line :
XmlSerializer serializer = <br />
new XmlSerializer(typeof(MyCoulumnClollectionClass));
when i remove "m_columnTable" , it is ok.

NEVER use public fields - this is the worst programming concept you could do, except perhaps in the case of private structs used only internally to your code.
If you don't want the DataTable serialized, making the field private (and any public properties that access it, attribute them with the XmlIgnoreAttribute) will take care of that automatically, since XML Serialization only serializes public and private fields (unless you implement IXmlSerializable, which is undocumented and requires that you know how it works internally).
A DataTable should be serialized as part of a DataSet, so if you want this DataTable serialized, define the field as private (besides, public properties or fields should never start with m_, that goes against naming guidelines), reflect the field with a public property attribute with [XmlIgnore], then make a public property declared as DataSet that instantiates a new DataSet, puts the DataTable into the DataSet.Tables collection, and returns it. You don't have to use it (and can attribute it with [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)]) - it's only for serialization.

Hi,
how can I call the default constructor of a class from an overloaded one? Example:
public class MainForm : System.Windows.Forms.Form {<br />
public MainForm() {<br />
InitializeComponent();<br />
PrepareSomeStuff();<br />
SomeMoreStuff();<br />
}<br />
<br />
public MainForm(string Somestring) {<br />
mSomestring = Somestring;<br />
InitializeComponent();<br />
PrepareSomeStuff();<br />
SomeMoreStuff();<br />
}<br />
}
Any ideas are welcome.
