He suggests Apple Chicago as a good font solution to a WinForms App. I would like to know what can be the best alternative of Apple Chicago font in Windows environment. Do you know any out-of-the-box or free-to-download mono spaced fonts that look el...
In a C# application, should a OleDBConnection be created once, or every time a SQL statement is executed? I am looking at C# code written by someone else. Every SQL statement is preceded with the creation of an OleDbConnection object whose connection string points to an MDB database. Is it appropriate to create an OleDbConnection obje...
Not sure what is the best way to word this, but I am wondering if a dynamic variable name access can be done in C# (3.5). Here is the code I am currently looking to "smarten up" or make more elegant with a loop. private void frmFilter_Load(object sender, EventArgs e) { chkCategory1.Text = categories[0]; chkCateg...
I'm noticing some strange behavior when I add a ComboBox to my Windows Form: when I resize the Form without a ComboBox, it behaves correctly and the File menu stays where it's supposed to stay even when I drag the right corner as far left as possible. When I add the ComboBox and I try to do the same thing, then the File menu gets pushed ...

I created a User Control derived of a Tab Page with certain controls such as ListView, Buttons, and Textboxes in it, to add Tab Pages to a Tab Control dynamically during run time.

If our UserControl requires certain properties are set for it to be useful, what's the best way to ensure they are set? Even if just as a note to self and/or close colleagues. We've tried using an Initialize method, but that's already caught us out because we forgot to update the Initialize in one instance, having slightly changed the d...

I'm searching for a .NET graph component. It should be able to plot data in sweep (oscilloscope) mode and if possible also as a scrolling waveform. On the x-axis I want timestamps (e.g. 18:25:00) and it should be possible to plot two vectors (DateTime[] and double[]). That is, data points are not equally spaced, but come with their own t...
I would like to display 2 forms side by side. Frm1 will call Frm2. The problem is, if Frm1 is too near the edge of the computer screen, when Fr2 is shown, part of it will be outside the screen. How do I make it so that if Frm1 is near the right-side of the screen then Frm2 will show on the left-side of Frm1 and vise-versa? Thanks ...

Disclaimer: In this question tab, page, an dialog actually mean the same thing, sorry. My excuse: I am not sure what the final product should look like - a bunch of separate windows or all in one. I am looking to improve an existing, hard-to-maintain Wizard baked with WinForms. I need to try to keep the look and feel about the same, but...
