Get Font for textbox with fixed width - vb.net

Having VB textbox control with fixed width. How to measure or set font size of the control for given string length ? The string/text should fit into the textbox completly.

You can use Graphics.MeasureString to measure a string drawn with a specified font. For example, cycle through several font sizes and pick one that fits best into your textbox width.
Another way, which supposedly works better with non-ASCII characters, is TextRenderer.MeasureText. Suggested by this answer.

Objective C multiline UILabel is not working

Here I have attached the scenario of my issue.
Current View
Here Top Title is a bit long string. But my view is shown partially.
Here I added the storyboard properties that I used for my UILabel.
Can someone suggest a solution to make this UiLabel as multilined one ?
You can't have a multi-line label with a fixed font size, if that label is constrained to a certain height.
Either the height needs to scale to allow more lines at that fixed font size, or the font size needs to scale down to fit all the text in.
If neither are possible, then the text will be truncated.
If your label is constrained to a certain height, then you can change the Autoshrink setting from Fixed font size to Minimum font size and specify the smallest size that you will allow the font to shrink to in order to accommodate longer strings.
Try to change the relation of constraint height: Greater than or equal

How to handle Segoe UI in pixel perfect layout (glyph "margin")

i am fighting with the layout of my windows store app. My problem is with the segoe ui font that I am using for the labels of some textboxes.
I have a borderless label above a textbox with a border like this:
LABEL
_____________
|__TEXTBOX___|
My problem is, that the font of the label does not align perfectly with the left border of the textbox.
First I though that it must be the label padding or something, maybe a padding or margin in the control template. But this is not the case. The true reason is the space around the glyphs within the font itself. Depending on the first letter or the size of the font the gap is bigger or smaller.
Is there a way to perfectly align the label text and the textbox independant of the first letter or the font size? Or do I really have to place every label in a different position to reduce this problem?

How to increase acrofield(textfield) size to fit text in itext?

I have a pdf template having a multi line textfield.While filling up the textfield at run-time using itext, I want to increase the textfield size so that the entire content is visible.
I know similar questions have been posted previously.e.g. the following link suggests a solution but I am too new to itext to make it work.
How to display floating textfield depending on the text content?
I know setting font size 0 automatically adjust the font size to fit in the text, but that is not an option for me since I can't reduce the font size.
So kindly provide me an workable example if possible.

Visual Basic Textbox number of lines

In VB.NET, I want to find out how many whole lines of text I could fit inside a multiline textbox. What is the best way to do this?
Considering that the WPF TextBox controls don't have a Multiline property, this is presumably for a WinForms application.
To determine how much text you can fit in a given size (the dimensions of the TextBox control) I would suggest using the TextRenderer.MeasureText method to determine the height of a single character. Divide the height of the TextBox control by the height of the character to get the number of lines visible at one time.
Keep in mind that the measurements of characters may potentially differ in so much that the measurement of an asterisk (*) may be very small, whereas the measurement of an octothorpe (#) may be much larger. The MSDN page seems to state however, that this is a non-issue as long as you use MeasureText(String, Font) and not any of the other overloads.

DataGridView Scaling

In VB.net 3.5 SP1 I have a Windows Form with three DataGridView controls. One DGV takes up the whole bottom half of the form. The other two share the top half and are side-by-side.
I'd like to have each DataGridView scale appropriately. More specifically I'd like to have column widths and row heights adjust to the size of the form. Then I'd like the cell font to auto-fill based on a change in the cell size.
I've used the Dock property for the controls to scale to the size of the form. How can I get the rows and fonts to utilize the increased form size?
Thanks.
You can use the datagridview.autosizecolumns and the datagridview.autosizerows to autosize the columns and rows. Look at ColumnHeadersDefaultCellStyle, rowHeadersDefaultCellStyleand RowsDefaultCellStyle to change the font
As for changing the fontsize, I don't believe there is any automatic way to handle this. You'll just have to write some code to change the font size based on the size of the datagrid.
