Use the toolbar control
Creating a Toolbar is not trivial. There are several steps to follow and some need to be performed in the right order. This HowTo's real usefulness is in its listing of the steps:
Press Ctrl-T to open the Tools dialog. Select Microsoft Windows Common Controls.
Add an ImageList control to the form.
Left-click on the ImageList and select the Properties command.
Click on the Images tab.
Click the Insert Picture button and find your button bitmaps. You can probably find the standard Windows 95 bitmaps in the Common/Graphics section of your computer's programming area. On my computer this is:
C:\Program Files\Microsoft Visual Studio\Common\Graphics\Bitmaps\TlBr_W95
When you have added all your button images, click the Ok button.
Add a Toolbar control to your form.
Left-click on the Toolbar and select the Properties command.
On the General tab, find the ImageList field (3rd from the top in my version). Select the ImageList control from step 2.
Click the Buttons tab.
Click Insert Button to add a button to the Toolbar. Fill in appropriate fields:
Caption appears on the button. For a normal button, leave this blank.
Key is passed to the Toolbar's event handler. This is one way you can tell which button was clicked. Enter a short key word here.
ToolTipText is displayed when the user lets the mouse rest over the button. Enter something short but helpful here. Remember that the user sees only a small picture if Caption is blank, so even very short text is useful here. For example, "Cut" is a good tip for the cut button.
Image is the index of the button's picture in the ImageList control. 0 means no image. 1 is the first image in the ImageList.
Experiment with the other button properties to see how they work.
When you have added all the buttons, click Ok.
Double click on the Toolbar to open the code editor in its ButtonClick event handler. This routine takes as a parameter a Button object representing the button pressed. Look at Button.Key to see which button was pressed.
Note that if you modify the ImageList after you have attached it to the Toolbar, you may mess up the Toolbar. For this reason, you should try to put every picture you will need in the ImageList first. Then initialize the Toolbar.
When the user clicks a button, the Toolbar control's ButtonClick event fires. You can use the buton's Key property to tell which button was clicked.
Private Sub Toolbar1_ButtonClick(ByVal Button As _
MSComctlLib.Button)
Select Case Button.Key
Case "Cut"
MsgBox "Cut"
Case "Copy"
MsgBox "Copy"
Case "Center"
MsgBox "Center"
Case "Snapshot"
MsgBox "Snapshot"
End Select
End Sub
Some additional tips from Gary German:
Toolbar graphics can be assigned from external files at runtime. But, the graphics on each toolbar must all be the same size, otherwise they'll look bad. Specifically, the first button to which a graphic is assigned "wins", and all following graphics will be stretched, if necessary, to fit in that same size.
Max number of buttons on a toolbar is 255.
If you need to create some buttons with graphics, and others with text only, don't use the button's .Caption property - it will cause all buttons to grow vertically because the text is placed below the missing graphic. Instead, use a routine to turn the text you want to display into a graphic, and assign this "graphic" to the image list, and then the toolbar button.
Press Ctrl-T to open the Tools dialog. Select Microsoft Windows Common Controls.
Add an ImageList control to the form.
Left-click on the ImageList and select the Properties command.

Classic VB - What is Option Explicit, and why should I use it?
What does it mean?
Putting the "Option Explicit" statement at the top of a code module (which includes forms/modules/classes/...) forces you to declare all variables that you have used in that module, using Dim or similar.
If you try to run your code when a variable hasn't been declared, it will be highlighted, and you will get a clear error: "Variable not defined"
Why should I use it?
You are probably thinking "errors are bad, I don't want that!", but this is actually a very good error - as it tells you about problems that are hard to spot otherwise.
Have a look at this code, can you see why it gives the wrong answers?
vb Code:
Dim MyVariable As Integer MyVariable = 10 MsgBox MyVariable 'should show 10 MyVariable = MyVariable + 1 MsgBox MyVariable 'should show 11 MyVariable = MyVaraible - 2 MsgBox MyVariable 'should show 9 Instead of showing us "10", "11", "9", the messages actually show us "10", "11", "-2"!
The reason for this is that I mis-spelt the variable name (MyVariable = MyVaraible - 2), so VB being 'kind' creates a new variable (which has a default value of 0), and uses it in the calculation.
In the code above it is fairly easy to spot the mistake, but the more code you have the harder it gets to find mistakes like this - generally all you know is that the code is not working properly, but you can't tell why.
Instead of spending lots of time trying to work it out, simply having Option Explicit at the top of the code file will tell you what (and where) the problem is, so all you need to do is correct the variable name (or declare the variable, if it was meant to be a different one!).
Can I have it added to my code automatically?
Yes you can, but only to new files that you create - you will need to add it yourself to existing files.
To have it added to all new files you create, simply select "Tools" -> "Options", and tick the "Require Variable Declaration" box.

ASP.Net 2.0 C# DateTime IFormatProvider Using ParseExact
In the previous article C# Convert String to DateTime you learnt the use of Convert.ToDateTime function in C# ASP.Net 2.0. Following are 2 other methods to convert the DateTime format using IFormatProvider:
DateTime .ParseExact
DateTime.Parse
To use IFormatProvider you have to pass the culture info for DateTime format coz in different cultures DateTime format of displaying the sequence of month and date varies.
E.g.:
For French Culture use the following:
IFormatProvider culture = new CultureInfo("fr-Fr", true);
For US English use the following:
IFormatProvider culture = new CultureInfo("fr-Fr", true);
Both cultures mentioned above accept the different DateTime Formats.
If you are using
DateTime.Parse
then you have to pass the MM/dd/yyyy hh:mm:ss
Format of DateTime for French culture and dd/MM/yyyy hh:mm:ss for US English culture. You have to check the format for different cultures by changing the position of month and day.
Using DateTime Parse:
dt = DateTime.Parse(myDateTimeString, culture,DateTimeStyles.NoCurrentDateDefault);
Using DateTime ParseExact:
dt = DateTime.ParseExact(myDateTimeString,"MM/dd/yyyy hh:mm:ss", culture, DateTimeStyles.NoCurrentDateDefault);
C# Code to ParseExact the DateTime String:
string myDateTimeString;
myDateTimeString = "19/02/2008 05:44:00";
IFormatProvider culture = new CultureInfo("fr-Fr", true);
dt = DateTime.ParseExact(myDateTimeString,"dd/MM/yyyy hh:mm:ss", culture, DateTimeStyles.NoCurrentDateDefault);
Response.Write(dt.Day + "/" + dt.Month + "/" + dt.Year);
DateTime .ParseExact
DateTime.Parse
To use IFormatProvider you have to pass the culture info for DateTime format coz in different cultures DateTime format of displaying the sequence of month and date varies.
E.g.:
For French Culture use the following:
IFormatProvider culture = new CultureInfo("fr-Fr", true);
For US English use the following:
IFormatProvider culture = new CultureInfo("fr-Fr", true);
Both cultures mentioned above accept the different DateTime Formats.
If you are using
DateTime.Parse
then you have to pass the MM/dd/yyyy hh:mm:ss
Format of DateTime for French culture and dd/MM/yyyy hh:mm:ss for US English culture. You have to check the format for different cultures by changing the position of month and day.
Using DateTime Parse:
dt = DateTime.Parse(myDateTimeString, culture,DateTimeStyles.NoCurrentDateDefault);
Using DateTime ParseExact:
dt = DateTime.ParseExact(myDateTimeString,"MM/dd/yyyy hh:mm:ss", culture, DateTimeStyles.NoCurrentDateDefault);
C# Code to ParseExact the DateTime String:
string myDateTimeString;
myDateTimeString = "19/02/2008 05:44:00";
IFormatProvider culture = new CultureInfo("fr-Fr", true);
dt = DateTime.ParseExact(myDateTimeString,"dd/MM/yyyy hh:mm:ss", culture, DateTimeStyles.NoCurrentDateDefault);
Response.Write(dt.Day + "/" + dt.Month + "/" + dt.Year);
