Warning: byte[], [XmlAttribute] and MTOM
I don't know if this is an intentional feature change, or simply a bug...
but!
I recently upgraded a web service to WSE3, specifically to use MTOM in a
particular call. This worked, however something else unrelated went "snap"
in the process...
After much head-scratching, I identified it as a public byte[] property that
was marked with as [XmlAttribute] - i.e. to be serialized inline with the
containing object-element. Under vanilla .Net WS everything was fine, but
with MTOM enabled this field ceased working - it would be read as 0 instead.
As it happens this represented a database timestamp, so it (oddly enough)
stopped a few things from working.
Changing this property to [XmlElement] and regenerating my proxy class
resolved this; this was the only change.
For ref, the markers in the proxy class changed from:
[System.Xml.Serialization.XmlAttributeAttribute()]
[System.ComponentModel.DefaultValueAttribute(0)]
To
[System.Xml.Serialization.XmlElementAttribute(DataType="base64Binary")]
Also note that I generate the proxies via
@"C:\Program Files\Microsoft WSE\v3.0\Tools\WseWsdl3.exe" /edb
/type:webClient /nologo /l:CS /n:%2 /out:%1 %3
(with obvious %1...%3; just included to indicate full calling syntax)
I've resolved it now, so I'm not panicking, but does anybody know if this is
by design? As I wasn't expecting it!!!

Implement a link source (or at least part of one)
I want to be able to drag objects from a third-party product to my .NET
Winforms app. If I look at the clipboard formats, there is nothing useful
except CF_LINKSOURCE, so I deduce that I need to do some OLE handshaking
(OleCreateLinkFromData, IPersistStorage, etc.). Does anyone have any
pointers as to how to do this from C# (.NET 1.1 preferred, .NET 2.0
acceptable). Thanks in advance! Tag: VB6 and .NET MDI Tag: 97296

causes validation problem
Hi,
I have two buttons and a text box on my form amongst other things. The
textbox is set to validate to see if there is no text in the box. The two
buttons are set "causesValidate = false" . One of the buttons is in a group
box. The other is on the form. The button on the form doesn't respond to the
validating event as would be expected, however the button set in the groupbox
continues to call the validating event despite it being set to false.
Is this normal? Does the group box change something? If so, what should I do
to stop the button in the group box from responding to the validating event?
Any suggestions will be gratefully appreciated.

how to make an image draggable?

I tryed to look at what IE does and when I drag animage from IE it has the
follwoing formats:
[0]: "UntrustedDragDrop"
[1]: "FileDrop"
[2]: "FileNameW"
[3]: "FileName"
[4]: "DeviceIndependentBitmap"
[5]: "HTML Format"

byte[] imageData = ....;
Bitmap bmp = new Bimtap(new MemoryStream(imageData));
DataObject dao = new DataObject();
dao.SetData(DataFormats.Bitmap, bmp);
dao.SetData("DeviceIndependentBitmap", imageData);
But that doesn't work....
Beside when I drag from IE the form DeviceIndependantBitmap is a stream,
whereas with my code I generetae either a byte[] or a proxy
what could I do?
I would like to drag image from my application without having to save them

Inheriting a from with a special constructor
Hi,
I created a base form, what holds several graphical elements (text boxes,
etc). This form has only one constructor, what expects one integer
parameter. Call this BaseForm
It's constructor looks like:
public BaseForm(int Param1)
{
InitializeComponent();
}
Now I inherit a second form from this one (Call this InheritedForm), and I
found out, that I have to define the constructor as follows:
public InheritedForm(int Param1):base (Param1)
{
InitializeComponent();
}
Now, my problem is, that in the designer the form can not be shown, since
there is an error:
Construcotr on type 'WindowsApplication1.BaseForm' not found.
Why? I defined the constructor! Moreover, if I create a second "default"
conrtuctor:
public BaseForm()
{
InitializeComponent();
}
is not helping at all.
How can I see in the designer the InheritedForm? How can I add more visual
components on it? What did I wrong?

How to make a dialog that is assigned to an MDI child
I have an MDI application, and I'd like to create a dialog box that appears

with an inventory list that pops up as a dialog box. But if the sales
person takes a call from a customer and has to check the status of another
sales order, I don't want them to have to close down the dialog box to do so

the product yet.

Databinding ComboBox with NULL values
VS.NET 2003
I have a Windows Form application, with a form that has various controls,
all of which are bound to a custom business object:
Class Employee
Private _employeename As String
Public Property EmployeeName() As String
Get
Return _employeename
End Get
Set(ByVal Value As String)
_employeename = Value
End Set
End Property
Private _positionid As String
Public Property PositionID() As String
Get
Return _positionid
End Get
Set(ByVal Value As String)
_positionid = Value
End Set
End Property
End Class
SIDENOTE: Yup, I'm stuck with the PositionID being a string instead of the
more sensible integer because of the existing database schema.
My question revolves around the fact that the PositionID can be NULL, and
the user needs to be able to set it to NULL as well. On my form, the
PostionID is selectable by the user with a ComboBox. Here is how the
ComboBox's DataSource is setup:
Dim positions As DataTable = BuildDataTable()
ComboBox1.DisplayMember = "PositionType"
ComboBox1.ValueMember = "PositionID"
ComboBox1.DataSource = positions
The ComboBox is bound to the Employee object as follows (like the other
controls on the form):
ComboBox1.DataBindings.Add("SelectedValue", emp, "PositionID")
The ComboBox's DropDownStyle is set to DropDown. I would like for the user
to be able to simply delete the ComboBox's text and have an empty string ("")
be propagated back Employee business object.
The only way I have found to do this is the following 2-part process:
1) add an extra row with "" as its value to the DataTable that is the
ComboBox's DataSource:
dt.Rows.Add(New Object() {"", ""})
2) add the following code to the ComboBox's KeyUp event handler:
If (ComboBox1.Text = "") Then
ComboBox1.SelectedIndex = ComboBox1.FindStringExact("")
End If
I would like to eliminate the part where i have to add a blank row to the
DataTable, is there a way to do this?
Please let me know if I need to provide more information.
Thanks!

Measurement Unit problem with Printing.

Capturing data from a separate application window?
Hi all,
I have found that I need to be able to write a windows application that is
capable of attaching to an independent windows application (one I haven't
written), and gather information. For example, this application gathers a
bunch of data from disparate sources, and updates a log file every 10
minutes. However, the data is rendered to a textbox (or at least it looks
like a textbox) in the application in real-time. So, I want to be able to
attach to this window and get this data in real-time as well, so that I
don't have to wait 10 minutes for this logs to update.
Does that make sense?
That said, I have no idea where to begin. I've found some applications that
seem capable of doing this, but I don't know how it is they are doing it.
If anyone has any information that they would be willing to share, to get me
started and headed in the right direction, I would really appreciate it.

get value from combo box

Here is what I am trying to do:

Also, the combo box has an id field (value member) and a display field
(display member).

Databind column to property on another referenced object...

namespace MyTest {
class MyTestForm : Form {
public MyTestForm() {
DataGridView grid = new DataGridView();
DataGridViewColumn col = new DataGridViewTextBoxColumn();
col.HeaderText = "Parent.Name";
col.DataPropertyName = "Parent.Name";
grid.Columns.Add(col);
col = new DataGridViewTextBoxColumn();
col.HeaderText = "Name";
col.DataPropertyName = "Name";
grid.Columns.Add(col);
grid.DataSource = new BindingSource(new Child[] {
new Child(new Parent("dad"), "son")
}, null);
this.Controls.Add(grid);
}
}
class Parent {
private string _Name;
public Parent(string Name) {
_Name = Name;
}
public string Name {
get { return _Name; }
set { _Name = value; }
}
}
class Child {
private Parent _Parent;
private string _Name;
public Child(Parent Parent, string Name) {
_Parent = Parent;
_Name = Name;
}
public Parent Parent {

ClickOnce publishing without uploading dotnetfx.exe
Hi,
I'm using ClickOnce to publish my application (MyApp.exe) to a web server.
The application relies on a seperate application (CommonControls.msi), whose
only purpose is to install a few third party components into the GAC. This
application only has to run once on the user's machine.
I created the product.xml and package.xml files, and this CommonControls.msi
correctly appears in the Prerequisites box when I'm getting ready to publish
MyApp.exe.
Since I want CommonControls.msi to be hosted on my web server, I select the
second download option (Download prerequisites from the same location as my
application).
Note that at this point both .Net Frameword 2.0 and CommonControls.msi are
selected.
I now publish MyApp.exe - everything works exactly as expected. The files
dotnetfx.exe and commoncontrols.msi are uploaded to my hosting web server.
However, now every time that I publish MyApp.exe, both these files continue
to be uploaded. This means that instead of a 1.5mb upload, I'm making a 25mb
upload each time.
My question is - how do I tell ClickOnce to upload the prerequisites
manually (i.e. should I ever change CommonControls.msi), yet inform the
client program (MyApp.exe) to download the prerequisites from the same
location as the application?
Many thanks in advance for any thoughts on this.

Taskbar title different from window form text?
I have an application that is currently running without the default
titlebar, because the client needs the ability to create their own
custom titlebar. The only way we have found to accomplish this is to
remove the 'Text' from our main form, and also have no control buttons
enabled whatsoever.
This is all fine and good, they get the standard windows border that
they like, with no titlebar. The problem comes when the application is
displayed in the Taskbar. Since we removed the text property from the
main form, the entry in the taskbar is blank.
Does anyone know any way to set that text in the Taskbar to something
other than what is in your form title? I have looked for API calls
etc, but have come up blank. The other alternative is to hide the
titlebar while still setting the text property for the form. If I set
the FormBorderStyle = 'None', it does just that, but then we lose the
standard border which the client claims is not acceptable.

RichTextBox question
I've been messing about with the richtextbox control so that I can select
multiple different fonts and change their styles, sizes etc together. But if
I test the performance this by filling the box full of characters there is a
noticeable lag while the update happens.
To do this I'm using the following code:
int selectionStart = rtbBody.SelectionStart;
int selectionLength = rtbBody.SelectionLength;
int selectionEnd = selectionStart + selectionLength;
for (int x = selectionStart; x < selectionEnd; ++x)
{
rtbBody.Select(x, 1);// Selects one character at a time
//Do code for checking/changing font styles, type size etc
}
It works perfectly apart from this delay. I've used unmanaged code to stop
the rtb updating while this is happening and it helps a bit.
Would it be more efficient if I manipulated the rtf directly in a string
builder and then placed it back into the richtextbox?
Looking at word, literally thousands of characters can be changed style,
font etc instantly. Does anyone know how they go about doing this?
Any help would be appreciated.

ResizeBegin & Change Size Programmatically
Here is what I would like to do. The app's main form is a MdiContainer
containing forms. When the user changes the size of the container the
child forms are resized, too. I need to catch the beginning and end of
the resizing of the child form. How can this be done.
This is what is done currently. The container overrides OnResize. In
this function the children's position and size is continuously adjusted
as the user keeps on resizing the container. In the child forms I have
overriden ResizeBegin and ResizeEnd. Unfortunately, they are not being
called as they only react to manual resizing and not to
programmatically changed sizes (like SizeChanged vs Resize). Are there
any events like ResizeBegin and ResizeEnd that also respond when the
resizing is done programmatically? If not what is the best solution to
achieve this besides the main form telling the children that resizing
begins/ends?

ClickOnce, MSBuild and multiple servers.
We're currently getting ready to deploy an application using ClickOnce.
We'll be placing the deployment on two servers. Because the app.config files
will need to point to different servers, we're using the revision number to
indicate which server it came from.
Currently, this means manually changing the version in the IDE and then
publishing to each server. Is there any way to automate this using MSBuild?
After looking around it appears MSbuild might be able to generate the files
for publishing, but they would then need to be copied to the publish site, is
this correct?
Can you specify the version number in the build?

backgroundworker Question
We have been using multi-threading in our application in 2003 with good
results. When we migrated to 2005 our old code blew up, so we rewrote our
code using the backgroundworker. It seemed to easy to be true. When we run
our application now it seems that the screens are running synchronously and
not Async. We usually have 3 to 4 backgroundworkers going at the same time
inside the activated event for the form. See the code below to show how we
are using the worker:
Private QueueWorker As New BackgroundWorker
Delegate Sub QueueDelegate()
Private Sub LoadInitialQueue(ByVal sender As Object, ByVal e As
DoWorkEventArgs)
Try
Dim ReturnAsync As IAsyncResult = BeginInvoke(New
QueueDelegate(AddressOf SetupQueue))
EndInvoke(ReturnAsync)
Catch exp As Exception
MessageBox.Show(exp.Message.ToString)
End Try
End Sub
Public Sub SetupQueue()
Try
QueueFlex.Redraw = False
dsNotifications.Clear()
dsNotifications.Reset()
Dim parm() As Object = {Main.oProperties.UsersBankLoanTeamID, 0}
DBCalls.AccessDataLayer.FillDataset("SelUserNotifications",
Main.oProperties.ConnectionString, dsNotifications, New String() {"queue"},
parm)
QueueFlex.DataSource = dsNotifications.Tables("queue")
FormatQueue()
QueueFlex.Redraw = True
Catch exp As Exception
MessageBox.Show(exp.Message.ToString)
End Try
End Sub
Do we have to use BeginInvoke & EndInvoke with this new component because
that seems like the bottleneck. If we do still need to use them what can I
do differently that would make the UI more responsive. It just seems that we
lost the UI responsiveness when we moved over to the backgroundworker. it
looks like it gets the data from the sql server async but it doesn't populate
the controls async so it looks sync.
I don't know any help would be appreciated. Tag: VB6 and .NET MDI Tag: 97191
Click Event on MenuItem with subitems
Hi group,
I have a MenuItem with some subitems. I don't want the Click-Event of the
MenuItem to show me the subitems, but to do something else - e.g. opening a
dialog. The subitems will be shown anyway by mouseOver.
MenuItem submenuImages = new MenuItem("Image", new
EventHandler(this.menuItem_Image));
or
submenuImages.Click += new EventHandler(menuItem_Image);
But this EventHandler is never accessed. Why?
I also tried to derive from MenuItem to create my own MenuItem and overwrite
it's OnClick - but it seems to me, that this is not possible.

problem in global catch for all exceptions
Hi,
I have added a try/catch block in the Main() method of my c# window
application to catch all exceptions in the application. But it is no
catching the errors thrown from timer's tick event. My code is give
below:
[STAThread]
static void Main()
{
try
{
Application.Run(new Form1());
}
catch (Exception exec)
{
MessageBox.Show(exec.ToString());
}
}
private void timer1_Tick(object sender, System.EventArgs e)
{
throw new Exception("throwing exception from timer..");
}
Now it shows a windows exception from timer's tick event. Can any on
help me to fix it?
Thanks in advance

Resetting Combo to original state
Hello,
I'm using a combo box and some text boxes on an input form. When the user
submits the input, all the textboxes should be cleared & the combo box reset
to the way it was originally displayed (order desc.)
How do I 'refresh' to combo box to display as it did? It is bound to a
dataset via DisplayMember & ValueMember so it was not filled
programmatically. How do I do this programmatically? (or not?)
Thanks in advance for any clues.

Richtextbox control question
Is there anyway to create similar behaviour to BeginUpdate and EndUpdate in
a richtextbox control? I've seen a few work arounds on the net but they use
unmanaged code.
Any help would be appreciated,
