Inserting A Character Into The Active Program?
Aug 30, 2009
I am writing a simple program that serves a similar purpose as the character map, but just for the Spanish letters with accents (������ & ������). Character map doesn't work for me because I have to highlight the letter I want to insert and then copy it and then paste it into whatever window I'm working with.What I want to make is a program that has buttons for each of those letters, and when I push the button for a particular letter, it inserts the character into whatever window was active before I pressed the button. I also want whatever window that was active before I pressed the button (the window I inserted the character into) to become active again so I can resume typing right after I press the button.I have programmed in VBA before, but this will be my first VB project. I have tried searching how to do it, to no avail. Where do I begin?

I want to insert a special character into a RichTextBox. The character is in a Medieval Latin font (Andron) which is installed on my machine.
When I open MS Word and select Andron as the font, then go to Insert Symbol, then scroll down till I find the symbol I want, I see that its Unicode value is A752, selecting it inserts it into Word OK.
Now, back to my VB2005 project: I have a RichTextBox on my form, and the Font is set to Andron. I have two buttons on the form. Behind the first button I have this simple
RichTextBox1.Text = RichTextBox1.Text.Insert(RichTextBox1.SelectionSta rt, "a")
Clicking this button simply inserts the letter 'a' at the insertion point, fine.
Behind the second button I have this
RichTextBox1.Text = RichTextBox1.Text.Insert(RichTextBox1.SelectionSta rt, ChrW(&HA752))
However, on clicking this button I get the ubiquitous square symbol, as if it cannot find that character, which is odd (to me) as the correct font is selected for the RTB, and that code is the correct code for the symbol I want.
Edit to add: I can now see that all characters up to Ascii (Decimal) 255 (which equates to Unicode 00FF) all display OK, but any value over that does not.

having problems getting one of 2 pictures displayed when I run the program. In a whole, this is a coin tossing program that, after the toss button is pushed, is supposed to show either a coin heads or tails image while also displaying True or False for heads or tails respectively. Additionally, a running tally of how many times heads and tails is displayed.The main issue right now is that when I press the toss button, no image is displayed, but True or False is displayed as well as the running number. After checking, running numbers correspond with the T/F results. The secondary issue is that a running tally is displayed, but instead of it being in a single or double digit increasing format, it shows up as 0011122223345666 as you keep pushing the toss button. I've researched books and the web to find out where I'm going wrong and to get more clarification on why it's not showing, but I haven't been able to decisive.

Is there a command or couple of code lines that will pause the running program for one or two seconds?
I have a program that checks the system time every 250milliseconds and I need to skip checking it three times the first time it comes back with ":00" seconds from the system clock.
Or another option would be to reset the timer to 1000 and then back to 250...

I have created a little program that helps me keep track of tons of data by inserting it into sql. I created 5 forms and all 5 can insert data at the same time, but mostly just 1 of these is working continuously. I have noticed that the program will run, then at random times it will stop responding (can't minimize/click on anything/data entry stops), and the only way to stop is to kill the task. I can't even click in the debugger to set a break point when it happens, and setting breakpoints before debugging is useless as the program could run 2 hours and stop, or 10 minutes and stop. 5 forms, they open different excel files, insert data into sql, and repeat.

I'm trying to do program that do something with F1 and F2 keys. So all working while my program is active. If my program is on screen. If I'm using other programs and my program isn't active on screen then these buttons won't do anything.
My code so far:
This is under load program :
Me.KeyPreview = True
This is when keys are pressed :
Private Sub frmMain_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.F2
MessageBox.Show("F1")

I'm writing a small app that finds the directory of an active program and displays it in a message box. e.g. Microsoft Word is open and running... click a button and the app finds the Microsoft Word's directory. It has to be able to differentiate between the active program and inactive copy of the program.

I have several HotKeys setup in my program that functionally are working, my problem is with the dispaying of the text. The underscore does not appear when the program is running.I have several radio buttons that have the text property set to something like "&1 Fold" while in design mode the underscore is present, but when the program is running the underscore is not present. FYI the background is set to transparent.

In ancient time, we can specify all characters with chr(56)
For example, say the character is unprintable. We want to put it in a string. Just do
Dim a as string = chr (56)
Now we have UTF8 or unicode (or whatever encoding).[code]...

Is there a way to detect a Chinese character in a string which is build like this:
dim test as string = "letters 中國的"
Now I want to substring only the Chinese characters. But my code is database driven, so I can't substring it, because the length is always different. So is there a way I can split the string, from the moment I detect a Chinese character?

The program I am working on uses arrays and a text file. In one section of the program it's suppose to display the most active year for storms between the years 1990-2008. The year that has the most active storms is 2005, but I don't know how to write it in the code so that it displays. Attached is the text file.
So far I have a For Next loop that counts the arrays.

I recently made a simple pseudo-encryption program that changes each character into another. It is capable of encrypting and decrypting a string. This can also be done to any text file as well. The characters range from ASCII 32-254 (This on it's own may be an issue because of #127 being DEL).
Because I believed my own coding may be at fault, I attempted this with Triple Des with identical results.For Triple Des, the requirements for en/decryption was:
Encrypt: String to Byte
Decrypt: Byte to String
And to change them either direction, I used UTF8. I also attempted ASCII and UTF32, but I don't know what I should do. I am considering dropping this but I want to learn problems like this because I am currently in college and haven't started my core classes for programming yet and want the head start.
The point where I have come into a problem is attempting to do this to another file type like an image. I looked at the results from encrypting then decrypting and the results were similar, but it seems file encoding must be the culprit.

The latest assignment from my teacher was to create a console program where the user enters a character and the respective ASCII value in Denary, Hexadecimal and Binary, Even Parity, Odd Parity and Hamming code is returned.I've managed to implement all of them except the latter with relative ease, I am familiar with the concept of Hamming code and can compute it easily by hand, but don't really know how to implement it as a function in my program.

I am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.
