vb.net - Text box cursor manipulation -

-

I was fortunate to find a solution to my problem, so I have come up with a new one.

My program is multi-tab calculator, and for the user input I am making a goal for full keyboard navigation. I have my boxes in a grid, and the keypointe for every box is all that allows the user to navigate between the boxes to hide the arrow keys, using the arrow.

I have a problem in finding out, if I input something in the box and make a mistake (during the runtime), then I have to either equalize the number of X and type it again Or change the cursor to a single character in the situation I'm looking at the need to use the left and right arrows to navigate the cursor position in the text box, but want to keep some navigation functions I

So I have some questions based on this. / P>

Is there any way to detect the position of the cursor in a text control? If so, then the cursor position is called numeric? That is, at the beginning of the position = 0 box, position between first and second characters = 1 and further.

I am trying to write a sub which will count the characters in a string, decide whether the cursor is to the left or to the left of the left string and then allow the appropriate step in the next box when it Ho. 

  Private sub counters () 'I do not know about the syntax yet, I am currently researching this, so please' me, I try to fulfill my concept I am doing Integer txtBoxCount as dim txtBoxCount = txtBox1.Text.count '??? TxtBoxPos txtBox1.cursor.position.get '??? as integer In the end, sub-sub-sub-sub-sub-on () counters () if E. KData = keys Then E. Like I'm typing in appressknpress = true, I realize that I might need to change it, but for now it is suppressing the beep if txtBoxPos & gt; 0 Then move 'cursor to the box' ??? Otherwise if txtBoxPos = 0 then the next box is liquid.focus () end if the end ends if sub

anyhow, I am researching it, and finding my own answer Will work for Just hope that there may be any such thing as possible, if any light is possible, and if I am on the right track, can anybody put light?

Be humble, I teach myself only for a few weeks.

I'm not sure how I got control over the form, but in the text box There is a property that tells you where the carat is, and it is called.

Despite the name, it also works even when any text is not really selected

Oh, and you set the length of the string There is no need to write a method: Just use the property since you are new, so remember that the string null (or nothing VB is in colloquial) So, you have to check whether the length is before use. Generally, text will not be property null , but you want to keep this in mind.

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

I am thinking that there is something that I can do better so that my process list should start with the command with MySQL Be clear Currently I am looking for a lot: 17325 user_a localhost db_1 sleep 1132 NULL 17464 user_a localhost db_1 sleep 1124 NULL 17983 user_a localhost db_1 sleep 1078 null 18113 user_a localhost db_1 sleep 1068 NULL 18207 user_a localhost db_1 sleep 1060 NULL 18231 user_a localhost db_1 sleep 1058 NULL 18353 user_a localhost db_1 sleep 1047 NULL 18447 user_a localhost db_1 sleep 1040 null 18489 user_a localhost db_1 sleep 1036 NULL 23408 user_a localhost db_1 sleep 637 NULL Something in my phpscript is that I want to clean it Can i The script looks like: Select the ID from $ q = 'db_1 where fkId = 2'; $ Ar = mysql_query ($ q); ($ Line = mysql_fetch_array ($ qr)) {echo ($ row ['id'];} Thanks in advance! I'm guessing that when you have 10 threads, you're constantly using the connectio...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
