Hi,
I have a seemingly simple and common requirement, and I can't seem to find a solution anywhere. A number of people have posted this question in other forums, and they never get an answer.
I have a custom control, which is an editing panel for a document. It draws text using Graphics.DrawString().
Now, say the user creates a textbox, fills it with some text in my editing panel, and sizes the box so it exactly fits the text. When the document is printed/previewed (using PrintDocument), and the exact same DrawString methods are used, the text is off a little bit, causing it to wrap differently. I've confirmed that MeasureString returns a slightly different value, depending on which Graphics object is passed in (the editing control or the PrintDocument).
The only difference between the two Graphics objects is the DPI. The control has 96x96 DPI, where the PrintDocumenth has 600x600. I set all the text rendering hint and all that to be the same. For one sample string I tried, MeasureString for the control returned 169, and MeasureString for the PrintDocument returned 173. That means that if the textbox is 169 pixels wide, it shows up fine on the editor control, but it will wrap on the PrintDocument.
How can I consistently print text to both mediums, so that the editor is truly WYSIWYG?
P.S. I've tried every font measurement with the same results (i.e. px, pt, em, etc)

MeasureString is not very reliable I have found, that's why I only support fixed width fonts in my IDE.

ya, unfortunately that is not a viable solution in this case - full font support is necessary.

Nobody knows how to produce consistent text output regardless of DPI?!?

For those interested - I finally figured this one out...it was quite a pain to nail down. Instead of printing directly to the 600dpi graphics object, you create a temporary image that is 96dpi (same as screen), but with the same resolution as the printer. You then do a ScaleTransform so that your text is scaled from the small screen resolution to the larger image resolution, and since the DPI is the same, the text measures up exactly the same way!
Then you simply take the temporary image and dump it into the print graphics object, and woohoo! WYSIWYG! (you have no idea how much dicking around it took to get it all perfect lol, so I'm pretty excited)
I might just have to write an article on this...although strangely enough, while trying to find an answer to this problem, I couldn't find ANYTHING on it...which makes me think there isn't too much demand for this sort of thing. Does nobody create WYSIWYG editors?? If you want me to write an article, post here and let me know!

I am trying to write some code that will capture a screenshot of an application along with the details of the last action a user undertook (clicked on a button, entered text in a field...). The capture would be initiated by the user - the app will help author eLearning/simulation content.
I have the code to capture the screen as well as the coordinates of the mouse when the user clicks. I cannot figure out how to trap the name of the field / button / list entry etc. that was clicked. Initially, I am looking to do this for a web app.
Any help with doing this would be appreciated.

every default event has an object named "sender", you can use it to know who called that event, take your example, you want to know the caller control's name, then just convert the sender to your caller control, like this
Button tmp_button = (Button)sender;
MessageBox.Show(tmp_button.Name);
hope this will help

if you don't know the class, cast it to control
if (sender != null)
(sender as control).name

Hi,
I would like to create an options dialog such as Windows Live messenger has.
Basicly I would like to use a listbox to control the tabPages in a tabControl.
Unless; you have a better Idea to create such a dialog...
thank you

What is wrong with the tabs themselves?
|
|
|
|
|
Just handle the SelectedIndexChanged event of your listbox and do something like this in there:
tabControl.SelectedIndex = ...;
tabControl.SelectedTab = ...;
I don't use Windows Live messenger, so I hope that's what you actually wanted to know.
regards

hello,
I have 2 problems that i have with drawpanel
1) When i minimize i want to redraw my paint, i have event resize that do occurred
and update flag (FirstRunt=true)
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
if (FirstRun)
{
FirstRun = false;
if (rbByDistanceDendogramView.Checked)
DrowNamePanel(0, 2);
if (rbByLevelDendogramView.Checked)
DrowNamePanel(1, 2);
if (rbBySequenceDendogramView.Checked)
DrowNamePanel(2, 2);
}
}
function DrowNamePanel knows how to draw semetric to sizes
when i enlarge my form its works properly
2) when paint is hidden by another window/application area that was hided are dissapearing
so how can i recognize when it's happened and than redraw my draw.

Why are you only drawing when FirstRun is true? Why not just draw every time your form is painted?
The on paint method gets called when the form needs to be redrawn, like when you minimize, something covers your form up, etc.

Hello all,
In my webservice, in a webmethod named emData, I am extracting some data from a sql server database and arranging those data in a DataSet following some query. Now that DataSet is the return value of my webmethod emData. I am working with C#
How can I show that dataset in my client winform in a normal table after receiving it from the webservice?
Please help me to solve this out.
with regards,
Faysal

The dataset returns a set of tables (or maybe just one in your case). Just bind that table to say, a datagrid. That'll display the data and you can work your way through other bindings afterwards.
emData.Tables -> specify the table name (string) or index (int) starting with 0.

Warning 2 'System.Configuration.ConfigurationSettings.AppSettings' is obsolete: 'This method is obsolete, it has been replaced by System.Configuration!System.Configuration.ConfigurationManager.AppSettings'

Make sure you include a reference to the System.Configuration assembly in your project references.

Looks like you are trying to add this line in the class level where variables are declared.
Try using it insie the function / main where you require it.
Thanks
