Hi all,
How would i go about inserting a breakpoint after each 500th character. You see, i have created a flat file using ssis. This packaged reads records from a database and writes it into a flatfile with fixed length. BUT the records do not get written underneath each other... The get written next to each other and this is then a problem when i need to write the final flat file (a combination of three flat files).
The records (read from the database [sql]) gets written like this:
Text Line1Text Line2Text Line3
I want it:
Text Line1<br />
Text Line2<br />
Text Line3
To do this (i think) i need to do something like this...
Read the text line from the datafile into a variable. (this is the text file with the datarecords next to each other)
Take the length of the variable and devide it by 500. (This is because each record / text line is only 500 characters long. This will then be stored in another variable called: Lines)
Then i do a for loop for each line, taking the first 500 characters from the variable and writeln it into the text file. Now delete/remove the first 500 characters from the variable (as to not write them again) and do the same with the next 500 characters until the end of the Lines loop ended.
I dont know if this could be prevented (what i mean is: Can you tell the SSIS Flat File Destination control to write each record into a new line??) if NOT do you think my theory would work using vb.net code?
Thank you in advance.

Never Mind...
I figured it out.
I inserted a new breakpoint (using writeline) after every 500th character.

Hi. I would be considered beginner at VB so I hope this question is not bad.
I am working on a genetic algorithm for TSP problem. I will try describe what I am trying to do. I am try to create 10 x 10 matrix has zeros across in cells diagnal from upper left to lower right. For example: in TSP problem distance from point A to A, B to B, C to C, etc will have be zero. I am create random integers from 1 to 100 for other distance. So upper right and lower left must be also symetric. I can create matrix so each cell is random but can not do previous stated problem.
I hope this makes sense.
Any help is many appreciated.

Have you made any progress in this?

Yes, it was just a matter of entering:
_Array(y, x) = _Array(x, y)
_Array(x, y) = 0
_Array(x, y) = _Array(y, x)
in the middle of my nested for/next loop.
Thank you for the interest though.

Hi, I have develop any application in vb2005. My application connect to ms. access database. i used textbox to display information and editing in my application. My problem challenge when i try to format the number in currentcy and return the value back to the database when user need to update the value.
In my database there is one field has datatype as currentcy. When its display in the textbox i use the code format(value, "$ #,###.##") to display the value. For example, 6000 display $ 6,000.00. The problem is when i try to save the value back to the database, the value $ 6,000.00 will cause the problem because $ , and . character is not a valid character.
So, how could i code my application to take only 6000 value from the textbox which contain $ 6,000.00 value? Do i need to use any custom control?
Thank in advance!

You can change the control to not accept those keys, but if you like the way it displays, just string the string before you insert it, as in
currency = txtCurrency.Text.Replace("$", "").Replace(",", "")
That will replace $ and , with empty strings, giving you the format your DB requires

Your issue is, your user needs to install SQL Server ( which is not free, unless you can use the Express Edition ) and then either attach to an existing blank DB, or run a script to create it. It's not as simple as deploying an MDB file.

Why are you using VB6 ? It's outdated, unsupported and it sucks. I know there are webservices around for SMS, but why do you want to use SMS ? How does SMS come into play ? If the user is booking online, why would they need SMS for the number ? You can't run VB6 on a phone, can you ?
When you say you're 'new to this' do you mean VB6 or SMS ? Why are you wanting to write this ?

Dim index As Integer
index = listbox1.SelectedIndex
listbox1.Items.RemoveAt(index)
The above code is used to remove the seleceted item from a listbox. However the program crashes when the button is clicked and no item is selected. How can I correct??
|
|
|
|
|
Check the value of SelectedIndex before you use it. SelectedItem will be -1 if there is nothing selected.
You might also want to check to see if the number of Items in the Items collection (see it's Count property?) is greater than zero before you try to remove something from it.

As the other posters above have stated, SelectedIndex will return -1 if there is nothing selected, so all you have to do is write an IF statement around it.
Dim index As Integer<br />
<br />
index = listbox1.SelectedIndex<br />
If index > -1 Then listbox1.Items.RemoveAt(index)
