Retrieving a number from a comboBox value including number and text

Posted By:      Posted Date: September 06, 2010    Points: 0   Category :Windows Application
Hi, I am using C# and trying to retrieve a number from a value in a comboBox that contains both numbers and text.  I am modifying what is in the comboBox using the following format which is working fine ("130mm Corus-Comflor 46" is a value already loaded into the comboBox):   this .floorComboBox.Text = "130mm Corus-Comflor 46" ;   This line of code is changing what is in the comboBox and from what is written in the combo box, I would like to be able to retrieve just the first number '130' from the newly updated comboBox so that I can use it elsewhere.  I am not sure how to go about this and I have looked online for something similar, but with no luck. Best regards, Mike

Searching for a unused number in Text file


Hello :)

I have a text file which looks like this :

Item 1
item 2
item 3
item 4
item 5
item 7
item 8
item 10 

(the text file exceeds 1000 lines, this is only a small part of it)

What I want to do is to find the first unused number( in this example it's 6) and let's say I want to print it in a text box.

The code I wrote for it, causes the program to freeze for maybe a half minute , so I hoped someone here could show me how they would solve this problem with
a less time consuming manner :)

Thanks on advance.

How to change default category for the Text Box Property NUMBER across multiple textboxes


I'm using SSRS R8 and have several reports with numerous NUMERIC textboxes.  The default NUMBER category that SSRS applies is "Default", which applies no formating to the number values shown in the textbox.  When the report executes, it displays these values with 4 decimal places (e.g. 123.1234).  The customer requires 2 decimal places (e.g. 123.12). 

This can be easily fixed by changing the category for the NUMBER Text Box Property from "Default" to "Number", with "Decimal Places" set to 2.

The trouble with doing it this way is that each report has over a hundred such textboxes (there are 15 such reports), and to change each textbox individually would be timeconsuming and error prone.  The intuitive way to do this would be to select multiple textboxes that I want to set the NUMBER category for, right click, select Text Box Properties, and set the NUMBER category accordingly.  However when I right click the multi-selected text boxes, I see the Text Box Properties option greyed out.

Is there a different way to do this?

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Embeb a variable number of videos


I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?

Article commenting by line number


I'm wondering what's the best way to approach an online article system that allows users to comment by clicking on the line they are commenting about? Essentially the same way Adobe Acrobat works with comments where you can click anywhere and the text is saved for that location.

I'm assuming a mix of jQuery would be the crux of the interface. The system would need to save comments so that when another user logs in, they will also see the other comments but they can´t edit them - only add their own.

Any suggestions would be great.

ActiveX and Visual Basic: Enhance the Display of Long Text Strings in a Combobox or Listbox


The combobox and listbox controls in Visual Basic have no built-in support for displaying text strings that are too long to fit in the visible area of either control. This article describes several techniques to improve the readability of long strings in each control. The first technique uses tooltips to display a combobox or listbox item. The other techniques, which use various Windows APIs, include adding a horizontal scrollbar for a listbox and determining the necessary width of the longest string given the font attributes of the text. The required steps are described for both comboboxes and listboxes.
