Hi,
is there a way to split the picturBox on demand, so that only everything underneath the diagonal is usable to paint on it?
|
|
|
|

Hell, no. A picturebox is a close to useless control, it's only value is to draw pictures for people too inexperienced to handle their own paint event. If you draw it yourself, you can use an ImageAttributes object in a DrawImage overload of the Graphics class, to specify a color range that would be transparent. This would occur in the Paint event.

Hi Christian,
thanks for your answer. Like i said in the other thread, i unfortunately can't use something else than a picturebox.
Maybe i can draw a graphic(in my case a triangle) in the pb-paint event and set it to be always in the foreground or something like that?!
It's only important that a part of the pb seems to be empty no matter if there was something painted or written.

Hi,
I have created an Outlook 2007 plugin using VSTO and I am getting an error that I hope someone out there has seen and could help me fix.
The plugin (add-on) is a command bar that simply waits for a (email appointment, or task) property to change (MS CRM stuff - gets changed by Microsofts CRM Integration) and then shows a Windows form asking for a Category. Everything works great unless I follow a very specific set of steps.
What I mean by that is I can get the form to popup a hundred times for Emails, Tasks, and Appointments and never have a problem. Then if I do an appointment a certain way, it blows up and then it will do it for everything until I restart Outlook.
This is the error message I get...
Unable to cast COM object of type 'System.__ComObject' to interface type 'System.Runtime.InteropServices.UCOMIConnectionPointContainer'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{B196B284-BAB4-101A-B69C-00AA00341D07}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
I can find almost no information about UCOMIConnectionPointContainer other then it looks like it is depricated in the .NET Framework 3.5. The odd thing is where this error is occurring, I am not actually trying to cast to a UCOMIConnectionPointerContainer object, I am trying to cast to an Outlook.Appointment object.
Here is the piece of code that causes the error....
if (m_Item is Outlook.AppointmentItem)
{
m_ItemType = OutlookItemType.AppointmentItem;
((Outlook.AppointmentItem)m_Item).CustomPropertyChange += new Microsoft.Office.Interop.Outlook.ItemEvents_10_CustomPropertyChangeEventHandler(Item_PropertyChange);
((Outlook.AppointmentItem)m_Item).Write += new Microsoft.Office.Interop.Outlook.ItemEvents_10_WriteEventHandler(OutlookItem_Write);
}
else if .......
This goes on to check for a Mail Item and a Task Item. Those never fail initially. It is always an Appointment item and once it fails, then I get the error for almost everything.
I hope somebody has seen this an can offer some advice.
Thanks in advance,
Wendell

I have a Windows form and I want to display a row across the bottom with a group of images.
The image location will be stored in a database.
I want them to be side by side in a single row. I know I can use a datagridview to display them vertically, but I am not sure if this can be done horizontally, nor am I sure if this is the right approach.
What is the right control to use for this? I want to be able to click on each picture and change the current record in the windows form to reflect the selected picture, I want to be able to scroll through the images (Horizontally only).
Is this a job for a repeater or datalist? Does anyone have a URL example of something of this sort?
Thank you in advance.

Hi,
I haven't done this yet, however my first attempt would entail a ListBox with its MultiColumn property set true.

All items the same color? Or different colors for different items?
If the latter and the ListBox won't do it, maybe try a TreeView instead.
|
|
|
|
|
The color off the text wil be the same as shown in the combobox.
for ex:
textbox - "Hello World".
combobox - Red.
When i press the button the listbox will show the line "Hello World" in red.

IMO that did not answer the question: if you choose red and click the button, then choose green and click the button again, would the ListBox now show two lines using different colors?
I understood it would, and that is what my earlier example does too.

But i still dosen't understand how to combine the click event with the
DrawItem event.
Can you please explaine me this?
|

Hi,
you don't have to worry about the firing of the DrawItem event, it basically works like the Paint event of any Control, i.e. it gets fired by Windows when (part of) the Control needs being redrawn because something happened (a Window on top of it has been removed, the user caused a scroll, whatever) OR your program told the Control something has changed (by calling Refresh or Invalidate).
So make sure the content of your Control is what you want it to be, e.g. on a button click, add an item to the ListBox.Items collection. And if something changes without the control knowing it, tell it to redraw with Invalidate().
Did you look at my example at all?

how i can get a volume serial number by c# language ?
|
|
|
|
|
By using the <a href="http://www.eggheadcafe.com/articles/20021019.asp">GetVolumeInformation</a>[<a href="http://www.eggheadcafe.com/articles/20021019.asp" target="_blank" title="New Window">^</a>] API.

That is a soft number, the doc says "This function returns the volume serial number that the operating system assigns when a hard disk is formatted." Not the real stuff.
