Drag and Drop events not firing
Ok, this is the first time I've tried a serious use of Drag and Drop.
As a test, I first defined 2 instances of a very basic user control on a
form. The user control had one string type public property. All the dragdrop
event handlers needed were defined automatically by VS from the individual
instances (MouseDown, MouseMove, DragEnter, DragDrop). (This was all based
on that article http://msdn2.microsoft.com/en-us/library/aa289508(VS.71).aspx
- Implementing Drag and Drop in VisualBasic.Net)
This test worked fine. (I also went back and assigned a panel as the 2
usercontrols parent. It still works.)
Now in the real application, what I want to do is dynamically define a
number of usercontrols based on the data and attach them to a panel. In
other words, define a loop and for each record:
Dim x as new UserControl1
-- define it's properties
-- Attach the event handlers
AddHandler x.MouseDown, AddressOf ControlMouseDown
AddHandler x.DragDrop, AddressOf ControlDragDrop
AddHandler x.MouseMove, AddressOf ControlMouseMove
AddHandler x.DragEnter, AddressOf ControlDragEnter
Now the event handlers aren't firing, not even MouseDown. I've set the
AllowDrop property of each control instance to True. What else could I be
forgetting? Tag: Minimize Window in IE 7 Tag: 113830
OnSetCursor
Hi, I'm extending an MFC app with a .NET control and i want it to respond to
::SetCursor, is this possible? Actually, i want the control to ignore the
SetCursor call and pass it on to it's parent.

WinForm with Dynamic Controls and Model View Presenter
Hi,
I have a WinForm control that has a tab control on it as its only control.
In the code I am dynamically adding controls to the tab control dynamically.
You could picture a page that gets populated with questions with either radio
buttons for choices, or perhaps combo boxes whose items come from the
database. All of these controls are placed on the tabs depending on answers
to questions - so if you answer "yes" to question "A" for example, then
another question may appear on this same tab, or a new tab may be added and
have additional questions on it. I am looking at doing this all using the
Model View Presenter pattern and was wondering if anyone had done anything
like this before? I am not sure what the best design might be to pass the
controls and data to the View as the controls will have to be "added" to the
tab control.
If anyone has done anything like this and has any recommendations, I would
be appreciative to hear about designs.
Also, I don't know if there would be any benefit from doing this using WPF
instead of .net 2.0 WinForms. Any thoughts about this would be appreciated as
well.
thanks in advance!

Use an icon inside a WinForm?
I'd say it's a dumb question... But so far I haven't been able to find a way:
I have some .ico... is there a way to use it INSIDE a WinForm? Like a simple
bitmap, but choosing which resolution (index) I want to display?
Thanks a lot.

Urgent - Controls on a form
Hi,
I am using Visual Studio.net 2005 to develop Windows Form applications
in C++.
My application is a Multiple Document Interface.
For each form opened I would like keep the controls (like picturebox,
buttons) but also other informations (another kind of information -
like and iplimage from the OpenCv Library)
For the first part, I need just to do
"form's name" -> Controls -> Add(""control's name");
How do I associate a class to a form?
Imagine my class is one which derive from another called Mdi
//File: OpenImage.h
ref class Figura : public MDI
{
public:
IplImage * srs;
}
//File OpenImage.cpp
#include "OpenImage.h"
Form ^Image = gcnew Form();
PictureBox ^pb = gcnew PictureBox();
pb->Image = Image::FromFile("lena.jpg");
Image->Controls->Add(pb);
Figura ^ImageCV = gcnew ImageCV;
ImageCV->src = cvLoadImage("lena.jpg", 1);
And now, how can I say that this class ImageCV must be added to the
form Image?
Any help will be very appreciated.

Clickonce: keep data files on uninstall?
Hi,
I'm getting my first ClickOnce app ready for prime time, but there's still
one thing bothering me:
At this moment I'm using |DataDirectory| to point to the SqlCe database. The
database itself is marked as "data file".
However, when I uninstall my ClickOnce app the SqlCe database is also
removed. What are my options to prevent this? Isolated storage? What would
be my connection string like?

scaling UI (higher resolution => bigger buttons + bigger font)
I want to create a UI with Windows Forms that should scale with the
resolution. It's some sort of demonstration UI to be used on
presentations.
For example: my application is always maximized and lets say it
contains 4 big buttons (in 2 rows and 2 columns) that completely fill
the screen.
When it runs on a 800x600 screen it should fill all space. When it
runs on a 1600x1200 screen it should also fill all available space.
I have already used a tableLayoutPanel but this only scales the
controls, not the font.
Is the tableLayoutPanel the right tool for this job? And can it also
dynamically change the fontsize? Tag: Minimize Window in IE 7 Tag: 113818
change location of control
Hi all,
I have a form that inherits from another form.
I want to change the location of a specific control. For this I have a
method in the base form which does only this:
public virtual void SetLocation(int x, int y)
{
myControl.Location = new Point(x, y);
}
I call this method from the inheriting form, like this: base.SetLocation(0,
0);
It doesn't work. The control's location changes but not to (0,0).
When I call this method from inside the base form it does work(changes to
0,0).
It looks like the inheriting form can't touch some certain area.
Can anybody explain to me what may cause this issue, and how to solve it?

Application deployment
Hi there,
I am nearing completion of my first real project in .NET and I'm looking at
the various deployment options. The clickonce alternative seems like the
ideal option for us, but my solution contains sevreal projects which make up
2 .exe files and a few .dll s which must be included in the installation.
It would appear that clickonce deployment only applies to a single solution
file, is there any way to combine multiple exe files into a single clickonce
installation that will take advantage of the autoupdate feature?
I have made a deployment project and that seems to work fine, but I really
need the update procedure of clickonce and if possible want to avoid any
major changes to the project at this stage.
Any help/suggestions are very much appreciated.

Using ComboBox in DataGridView with custom classes as datasource
Hello.
I'm working on a telephone directory lookup for an application and have
a custom class I would like to show in a datagridview.
The problem is that a person might have more than one mobile phone
registered, but the application expects only one, so the user will have
to choose one. My idea was to use a DataGridViewComboBoxColumn in a
datagridview to let the user choose one of the phone numbers.
This is the class:
public class PersonInfo
{
private string _name;
private string _address;
private string _workPhone;
private string _homePhone;
private string[] _mobilePhone;
public PersonInfo(string name, string address, string workPhone,
string homePhone, string[] mobilePhone)
{
this._name = name;
this._address = address;
this._workPhone = workPhone;
this._homePhone = homePhone;
this._mobilePhone = mobilePhone;
}
public string Name {
get { return _name; }
}
public string Address {
get { return _address; }
}
public string WorkPhone {
get { return _workPhone; }
}
public string HomePhone {
get { return _homePhone; }
}
public string[] MobilePhone {
get { return _mobilePhone; }
}
}
The problem is getting the numbers in the MobilePhone property to show
up. Is this at all possible?
Does anyone have some idea of how to do this? Tag: Minimize Window in IE 7 Tag: 113792

Help - Sudden crashes while editing DataGridView properties!
I have a fairly large winforms project, VB/Dot Net 2.0. While in the midst
of fairly routine editing I have suddenly found myself unable to click on the
'Choose Data Source' dropdown of DataGridView Tasks without crashing Visual
Studio.
This goes for all DataGridViews within the project and only this one
project. It does not matter if the the DataGridView has been setup already
or if it has just been put on the form. I am able to edit DGVs normally in
other projects. I have also tried rebuilding the solution and even
rebooting. Nothing works.
(One of my co-workers has just suggested that the solution itself is corrupt
and I should try creating an entirely new solution and copying over
individual files. I'll probably do that.) Tag: Minimize Window in IE 7 Tag: 113787
Drawing tabs in ListBox.DrawItem event
I have a ListBox, and have changed the DrawMode to DrawMode.OwnerDrawFixed.
I'm using the ListBox.DrawItem event to do some custom coloring in my ListBox
object.
My item strings contain tabs, but after drawing the items myself, the tabs
are not intepreted. Currently I'm just using the sample code given in the
MSDN docs for the event handler:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
private void listBox1_DrawItem(object sender,
System.Windows.Forms.DrawItemEventArgs e)
{
// Set the DrawMode property to draw fixed sized items.
listBox1.DrawMode = DrawMode.OwnerDrawFixed;
// Draw the background of the ListBox control for each item.
e.DrawBackground();
// Define the default color of the brush as black.
Brush myBrush = Brushes.Black;
int mod = e.Index % 3;
// Determine the color of the brush to draw each item based on the index
of the item to draw.
switch (mod)
{
case 0:
myBrush = Brushes.Red;
break;
case 1:
myBrush = Brushes.Orange;
break;
case 2:
myBrush = Brushes.Purple;
break;
}
// Draw the current item text based on the current Font and the custom
brush settings.
e.Graphics.DrawString(listBox1.Items[e.Index].ToString(), e.Font,
myBrush,e.Bounds,StringFormat.GenericDefault);
// If the ListBox has focus, draw a focus rectangle around the selected
item.
e.DrawFocusRectangle();
}
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
As I mentioned, my items contain tabs, and when I intercept this event, my
strings look like this:
"Name\taddress\tetc..."
Also, in case it matters, I'm setting my own tab stops in the list box:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
private void SetDeviceListTabStops()
{
// A tab-stop location of 4 equates to the width of one average
character for the specified font
int[] listBoxTabs = new int[] { 20, 75, 110, 160 };
// Send an LB_SETTABSTOPS message to the ListBox control.
int result = SendMessage(this.listBox1.Handle.ToInt32(),
LB_SETTABSTOPS, listBoxTabs.Length, ref listBoxTabs[0]);
// Refresh the List Box control.
this.listBox1.Refresh();
}

Problem rendering metafile text on bitmap.
Hi,
I have a problem with the quality from metafiles rendered on a
System.Drawing.Bitmap. In particular, text is drawn poorly. If the same
metafile is rendered directly onto a form's drawing surface, the quality is
fine. There's also a problem with scaling, with a difference in size between
the bitmap and directly drawn versions.
The code below illustrates the problem. It draws a string three times. The
top one is the string drawn directly on the form. The middle one is from a
metafile (with the string drawn onto it) drawn directly onto the form. The
bottom one is from the same metafile, rendered onto a bitmap, which is then
drawn onto the form. Top two look fine, bottom one not so good. Any ideas
what I'm doing wrong?
Thanks,
Chris.
Bitmap bitmap;
Metafile metafile;

What are my options for implementing a horizontal drag/drop contro
I have an interesting problem. I have a set of records in a data table
organized by a simple key. What I want to do is represent these records as
icons on a horizontally oriented control in asending order. Furthermore, I
want to be able to use this display to reorganize the order of the records in
the data table. i.e. If the control is displaying item1, item2, item3, I
want to be able to select item2 and drag it to the left so that the new order
in the data table is item2, item1, item3.
Also I want the control to have horizontal scrolling capability because
there will almost certainly be more than a few of these items.

options. Any ideas? Tag: Minimize Window in IE 7 Tag: 113774

Catching mouse events on all child controls
Greetings,
I've already tried googling for the following problem, but it seems
every solution I've found is too complex and error prone.
I've got a control (Panel) that acts as a container for several other
controls. These controls, in turn, have several other controls and so
on. I wish to be notified whenever the mouse is hover the area defined
by the container control, regardless of its children. OnMouseEnter and
OnMouseLeave triggers as soon as the mouse enters/leaves a child
control, so I can't use them. Same applies for OnGotFocus/OnLostFocus.
One solution would be to hook upon all events in every child control.
Despite the resulting complexity of event triggering (and the fact
that some controls can simply override the events I'm listening for
and inhibit them), the controls I'm using can (and will) change in run-
time (we are talking about adaptative interfaces here); this would
probably mean that I also need to hook upon the ControlAdded and
ControlRemoved events.
So my question is simple: is there any "clean" way for a control to
know that a mouse is in its area (ClientRectangle)? I don't mind if
the solution involves WndProc...
Best regards and thanks in advance,

Very weird RichTextBox bug
I have tried to make a simple sample of this - but the simple samples all
work. The basic problem is I create a RichTextBox and then call
RichTextBox.LoadFile() to load a rtf file in it.
If the file has an image in it - the control displays nothing and
RichTextBox.Text returns "". If I do the same thing in my simple sample
program, it all works fine.
Where it does not work I have a Word AddIn (IDTExtensibility2, not VSTO)
that uses DevExpress for it's ribbon forms, etc. In it to display the rtf
file I bring up a Form that has a RichTextBox in it and call LoadFile(). And
if the rtf has an image in it I get a blank control.
To try and recreate it I just did a plain old Windows form - no DevExpress
and no Word AddIn. But that works fine. Has anyone ever heard of anything
like this?

Set the row background color according to a cell value
Hi,
At this time I'm able to set the background color of a cell depending
on it's value. I'm able to achieve this by extending the
DataGridTextBoxColumn class and overriding the Paint method:
[code]
protected override void Paint(System.Drawing.Graphics g,
System.Drawing.Rectangle bounds, CurrencyManager source, int rowNum,
System.Drawing.Brush backBrush, System.Drawing.Brush foreBrush, bool
alignToRight)
{
if (internalHighlightInformation != null)
{
object objAtRow = GetColumnValueAtRow(source, rowNum);
//(Values A, C and X are just an example, this values
are set at run-time)
if (objAtRow = "B" || objAtRow = "C" || objAtRow =
"X")
{
backBrush = new SolidBrush(Color.Red);
foreBrush = new SolidBrush(Color.White);
}
}
base.Paint(g, bounds, source, rowNum, backBrush,
foreBrush, alignToRight);
}
[/code]
My problem now is, how can I do this to the full row? At this stage I
know the row number, and the cell, but I don't have any access to the
cells that exist in the same row :( (or do I?)
Any ideas? I just cannot figure out how to do this...

Component Designer
A great problem on VS2005. After I dropped an object on the designer area,
it does not maintain the position assigned. All objects, after closing and
reopening the designer, move on the left of the area.
It's hard to work in this situation. VS2005 SP1 resolves the problem?
Help me please!

Exceptons when debugging
My VB 2005 winforms application has an Application.ThreadException
handler to catch any unhandled exception.
When debugging, the debugger doesn't stop when I get an exception,
control passes to my application exception handler. Currently I
comment out the handler to be able to get the debugger to stop when an
unhandled exception occurs.
Ideally I would like to have the debugger stop when any exception
occurs, then optionally be able to proceed by having the exception
bubble up. Is this possible? Tag: Minimize Window in IE 7 Tag: 113741
PictureBox.Load and animated GIFs
Loading an animated GIF using PictureBox.Load causes an
ObjectDisposedException with the message "Cannot access a closed file" to be
thrown in the FileStream.Read method ultimately called by
ImageAnimator.UpdateFrames.
Looking at the output from ILDASM, it seems that the underlying file stream
is being disposed in the PictureBox.Load method. However, KB article 814675
states that the stream must not be destroyed for the lifetime of the image.
Can anyone shed some light on whether the .NET framework really is closing
the stream before the image is finished with.

Autocomplete textbox with dynamic datasource
I know how to use autocomplete with 2.0 framework on a textbox. I also know
how to use COM interop to use the IAutoComplete interface directly.
But with either approach I seem unable to change the list while the user is
typing.
I have an XML document and i want the user to be able to navigate to nodes
by typing in an XPath.
i.e. when the user types /A
it pops up with
/Animals
/Applications
and when they type
/Animals/
it pops up with:
/Animals/Dog
/Animals/Cat
I do NOT want to prepopulate the whole list.
However when using the .NET framework and changing the list I get an 'Access
Violation' exception which is unacceptable.
I tried to use the AutoComplete COM control (IAutoComplete) based upon this
blog entry :
http://jiangsheng.spaces.live.com/blog/cns!1BE894DEAF296E0A!732.entry
Unfortunately the control doesn't 'ask' for an updated list of items as I
type. I've tried all kinds of nasty tricks, like faking an 'Escape' key press
but none are acceptable because of unwanted sideeffects.
I essentially want the same behavior you get with the windows filename
autocompletion, but I dont see how I can achieve this. I might just have to
make my own autocomplete dropdown,but woudl rather not have to do that.
Any suggestions?

WebBrowser (loop automation)
Hello,
Background information â?¦.
I have a VS2005 C# Windows forms app which has several text fields, one
button control and one webbrowser control that I use to display an external
webpage and based on the input data provided by the user, I perform some
tasks on the webpage. The idea is to go automatically go through several web
pages based in data captured by the user until I reach to a desired webpage.
All this works fine,
The user fills the data on the windows form, then clicks on the form's
button and the process starts.
The click method of this button does something like like â?¦
private void btnSendData_Click(object sender, EventArgs e)
{
Uri myUri = new Uri (http://www.externalwebsite/page1.htm);
this.myWebBrowser.Url = myUri;
this.stageSecuence = 1;
}
I use a variable named "stageSecuence" in the next method to perform some
automated tasks depending on the webpage that is being processed.
Then for the webbrowser control I have the following method:
private void myWebBrowser_DocumentCompleted(object sender,
WebBrowserDocumentCompletedEventArgs e)
{
switch (this.stageSecuence)
{
case 1:
// perform some tasks like invoking the submit on the web page
this.stageSecuence++;
case 2:
// perform some other tasks
this.stageSecuence++;
// and so on
}
Current situation,
Now, instead of executing this automation on the webpage based on the data
manually typed by the user; I want to call this process several times based
on some database information.
I wrote the following code to perfom a loop (hoping to call sereval times
the automation process)
for (int i = 0; i < this.numberOfTableRecords; i++)
{
// get record info
Uri myUri = new Uri (http://www.externalwebsite/page1.htm);
this.myWebBrowser.Url = myUri;
this.stageSecuence = 1;
}
By doing this I only get the myWebBrowser_DocumentCompleted method executed
only once for the last record of the loop; in fact this method is executed
once the loop has finished.
How can I get the DocumentCompleted method executed once for every record in
the loop ?
Can I call this method manually such as:
this.myWebBrowser_DocumentCompleted( â?¦ ) ??
Thanks in advance,

Layout MDI problems with more than 3 windows
Hello,
When i use LayoutMdi with TileHorizontal or TileVertical and more than 3
windows the result is not the expected one and is the same.
When i TileVertical 4 windows i want them
===

===
=2=
===
=3=

===
(like ALL windows application does) but i got them :
======

If TileHorizontal : the result is the same.
Example VB Code :
You open a new windows application and paste this in Form1.vb
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
If Me.MdiParent Is Nothing Then
Me.IsMdiContainer = True
For i As Integer = 1 To 4
Dim f As Form1 = New Form1
f.MdiParent = Me
f.Show()
Next i
Me.LayoutMdi(MdiLayout.TileVertical)
End If
End Sub

Non-English Warnings
When I use OpenFileDialog.ShowDialog(), the dialog is in Dutch (which is
fine for the moment). It says 'Bestandsnaam' for Filename,
'Bestandstypen' for File Types etc. But when I select a non-existing
file, the warning is in English. How can I change the warnings to Dutch
(or to any other language)? Tag: Minimize Window in IE 7 Tag: 113720
Inconsistent image behavior in a Winforms app.
I'm writing a Winforms app in Dot Net 2.0. I created a few PNG images for
use as button images in order to liven up appearances a bit. I thought I had
given the images a transparent background using Paint.Net and they display
correctly on my own computer (a lenovo T60p laptop). However when the app is
run on another computer (A Dell desktop with a flat monitor, if I remember
correctly) the images have a white background. (The actual button background
color is the system default grey. I have not changed that.)
Am I forgetting some setting? Tag: Minimize Window in IE 7 Tag: 113719
Delete key in DataGridViewComboBoxCell
I have a DataGridViewComboBoxCell in a DataGridView. When it is

How can I override this default behavior and delete entire row
instead?

Capturing Shift+Return when AcceptButton is used
Hi,
I've got a search form with the search button used as AcceptButton for
the form and everything works as expected. However, I want to be able
to capture not only Return, but also Shift+Return in which case I want
to change some settings and then perform the search as normal.
As I understand it, when an AcceptButton is used the form's KeyDown
event handler doesn't receive the Return key event even with
KeyPreview on. If I remove the AcceptButton the Return key event gets
through as expected. Is there a good way to find out whether Shift is
currently pressed form within the accept button's Click event handler?
Is there a way to display the search button with "AcceptButton style"
without it actually being accept button?
Any thoughts would be appreciated!

Grid view readonly property
I am having problem with the fallowing piece of code
foreach (DataGridViewRow Rows in prePDDataGridView.Rows) {
Rows.DefaultCellStyle = null;
Rows.ReadOnly = true;
DataGridViewDisableButtonCell buttonCellSave =
(DataGridViewDisableButtonCell)Rows.Cells["Save"];
buttonCellSave.Enabled = false;
}
The above code will make all the rows in data grid view as readonly and the
button cell to disable.
The above code works properly when i made the form as non MDI child.
But it does not work if i made the form as MDI Child.
I dont know what is the reason. Any solution for this ? Tag: Minimize Window in IE 7 Tag: 113703
