hi
in gdi+ we have gdipStrokepath to make one pixel(unit) width edge of a path(text).
is there any api for draw text with any font and size ,but only one pixel width font?
for exam. create one pixel pen ...??
thanx

You can get the path that represents a string or a letter. Then you can draw it n the manner that I think you're after.

sorry i need a clear answer.
i already do it with a thinning algorithm , but if you work with Strokepath (gdi32) you find it very fast and easy.
i want to know is there a way to create one pixel width pen and draw text with this pen ?

I think what Christian said was that in order for that to happen, you'd have to get the outline description of each character, create your pen, and draw each character outline yourself.

sorry ,i think there is a misunderstood...
for outlining i have not any problem.
when you draw text in a picturebox for example ,if you increase font size 3 factors change : 1 & 2.width & height of text , 3.width of font
i want to create one pixel width font for any width & height of text.
for exam. in Tahoma when you increase font size until 14 the font width(not text width) stay one pixel.
i hope that was clear...thanks

No it doesn't. On mine, every stroke of every character is a minimum of 2 pixels wide, mostly 3.
I have no idea what you mean by "the font width stay one pixel". The font doesn't have a width. Each character cell has a width, but it's not usually measured in pixels and at one pixel wide, the character isn't readable.

Hi,
I have a mdi application where the mdi childs can not be maximized. Now i like to have a mainmenu in the mdi child, but it seems ok in vs but at run time the mainmenu of the mdi child is added to the mainmenu of the mdi parent.
How can I keep the mainmenu in the mdi child?
Thanks!

Not supported. The menus in the child forms get merged with the menu in the MDI Parent form. There is no option to put the menus in the MDI Child forms.

You could consider using the ContextMenu control. This you can add to each mdi child form separately.
For all intents and purposes the same, just looks different.

My advice is free, and you may get what you paid for.

Hello, I have a typical vb.net 2005 databound (strong typed ds, BindingSource, BindingNavigator) details form. The navigator moves the user nicely from one record to the other. The save button saves the changes and they are also saved as a group when the form closes..but..
Any one know how to update the db when the user moves records?
The form seems to want to wait and update the whole dataset when the form closes.. I want the updates written whenever the user 'leaves' the form.
I found a nice article here at codeproject on how to do this with a DataGridView but not with a regular details form: VB DataGridView Automatically Saving Updates to a Bound Database
The update code I can steal from what was generated for the BindingNavigator Save button...but the big question is....which object/event to use???
Thanks for any light you can shed on my dilemma!

It doesn't even wait for the form to close. Any changes made to the dataset are only written back to the database when the little blue disk is clicked. If you close the form before clicking that disk, all changes are lost.
If you want to automatically save changes when the use moves to another record, handle the BindingSource's PositionChanged or CurrentChanged events and call the Update method on the TableAdapter and pass in the datatable object, just like you find in the code for the little blue disk's Click event.
Private Sub CustomersBindingSource_CurrentChanged(blah, blah) Handles CustomersBindingSource.CurrentChanged
Me.Validate()
Me.CustomersBindingSource.EndEdit()
Me.CustomersTableAdapter.Update(Me.NorthwindCustomersDataSet.Customers)
End Sub

Yes

To load what? You haven't explained what you want to do.
I suggest you read the documentation on the ProgressBar[^] control and follow up your post if you have a more specific question.

Hi Pmarfleet
I don't want to show exactly the progress of something, is that I want the progress bar there to be like a decoration. You know like when you start your computer and it says Windows XP, you know there is a progress bar with the blocks passing by, I want my progress bar to be like the one when windows is starting up. I hope you understand.
Thanks, I hope is clear now.

What are you showing the progress of??
All too often this question comes up and the poster thinks that the progressbar just magically knows what it's showing the status of. You're code has to increment the progressbar every once in a while. So, what is it that you want to show the progress of??

Thank you very much and sorry for the misunderstanding, is that I'm just a newbie on this. I'm taking my frist class right now of Visual.

If I understand correctly you are showing a Splash Screen for a certain interval of time, and while splash screen is on screen you want to have a Progress Bar which will increment and show how much time has elapsed.
If this is what you are doing then you may have code like this-
---------------Code Start--------------------
On Form load set maximum and minimum value for Progress Bar, here I am using a timer which will show splash screen for 5 seconds, following lines will go in Form load event of SplashScreen –
Me.Timer1.Enabled = True
Me.Timer1.Interval = 1000
Me.ProgressBar1.Maximum = 5
Me.ProgressBar1.Minimum = 0
Now timer will run following code after every second and will also Increment the Progress Bar-
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
i += 1 'i is a Form level variable
If i = 5 Then
Me.Hide()
Else
Me.ProgressBar1.Increment(1)
End If
--------------------Code End---------------
I hope this helps .
-Dave.

Hi Dave:
You are almost correct my friend. I just did a copy & paste from this code you send me but it says that Name "i" is not declared. Ok I want the progress bar to be as the one when windows XP starts you know that it doesn't point the progress of windows starting, it is just there with the blocks passing by, that's want I want to do. My apologies for asking so much is that I'm a newbie working with Visual. Could you help me out.
Thanks

Then change the ProgressBar.Style property to Marquee and set the MarqueeAnimationSpeed to some value, like 250 milliseonds.

This is a VERY complicated topic, so I'll ask a simple question first.
Do you know how to write your own custom controls, from scratch?? That means you MUST understand completely how controls work and can write one from the ground up, providing all the properties, logic, rendering code, events, methods, ... So, do you??
