I understand all the code just fine. I found the issue with one of my data base fields. What is the best practice for updating my table? This application will run on user desktop and it is not web based?

Well, best practice is to use a parameterised query or a stored proc. I suggest searching for hte article on SQL injection and reading it.

Hi All,
I have a windows form program, which runs and compiles fine.
but along with the form window, there is a console window (black "command prompt" screen)
that also launches, none of my other window program have this behavior.
where can I stop the black window from launching?
I looked at all the code and can't find it, so I'm assuming is some settings that I need to turn off.
again, thank you all for all the help you have provided to this newbie.

Your project thinks it is a console application.
Go to the project's properties and check that the "Output type:" setting is set to "Windows Application" and the "Startup object:" is set to your main WinForm's class.

I have a panel of (800 by 600) when i do a print preview I can see the complete panel but when i do the print it cuts the right side veritcal line. During the preview my panel right side border line still away from the margin line. Any idea please

Hi,
most printers can't print up to the edges of the page; the printer driver knows the
minimal margins, you can try to cross them through the page setup dialog, and IIRC you
can read the settings in PrintPageEventArgs (one of the DoPrintPage arguments) and should
take them into account.

Hello Everyone...i'm creating a code that will scan LDAP and Active Directory for a fax number given to users and then it will compare both servers and will generate a text file with the discrepancies on both servers(only the numbers that don't match). The program seems to work but for some reason in the output i get a couple of users who have the same fax number in both servers. i wonder if i created the foreach loops correctly...can someone please guide me?????
namespace fax

// This sorted collection provides easy access to the FaxEntry objects added to it
// It also overrides ToString() to facilitate easy writing of results to the text file
public class FaxEntries : SortedList<string,>

// If list is not already built up
if (sb.Length == 0)

sb.AppendLine("XPID\t\tDisplay Name\tLDAP Fax#\tAD Fax#");
sb.AppendLine("-------------\t--------------\t-------------\t-------------");
// Iterate the collection and output each FaxEntry object via it's (overrided) ToString() method
foreach (KeyValuePair<string,> CurrItem in this)
sb.AppendLine(CurrItem.Value.ToString());

// Return the results
return sb.ToString();

 You'll get a better response if you use <pre></pre> tags around your code.
FYI: LDAP is a protocol and it is also used by AD

There's an option in Crystal Report like "To set up record selection using Select Expert"........but I notice that I would be able to only hard-code the values that are already existing in the database field.........rather I'm looking for something where I can get the value selected directly from the combobox..........am I clear with those lines.........I need help on this............TIA

you can use a parameter field, and set it at runtime, you could use a forumla field and change the formula text at runtime to return your value, or you could find a new product to use, i'm traped in the same place you are, trying to make CR dynamic...i've managed to an extent thanks to several online examples and "Crystal Reports .NET Programming" by Brian Bischof(not sure about the first name) but a lot of the features that made it so great for programmers have been removed in later versions the version for vs 6 you could almost build a whole report at runtime, and in 2008 you have to struggle to change anything at runtime, espically with any kind of chart. If you find a good alternative to CR please let me know.

Hello!
I have a question about retrieveing a toolstripmenuitem from a contextmenustrip.
In a certain function I do the following:
contextmenustrip.Show();
After that I would like the function to be halted until one of the toolstripmenuitems is clicked and this item is the returned into the funtion.
So I don't want to use an event but rather something like one can do with forms:
if (this.TestForm.ShowDialog(this) == DialogResult.OK)
Is something similar possible with contextmenustrips?
|

As far as I am aware their is no way to emulate a ShowDialog method for a menu. If their is a such a way you would have to work with Windows API or advanced menu events.

I have to read a large quantity of bianry data from a file and then store this data in an XML tag. There is approximately 8 MB of data.
This can be slow just to read the 8MB into memory using StreamReader.
I tried reading sayy 500k at a time. But i still have the issue of storing 8MB into memory.
If i would have just read 500k and then write 500k, i would be ok. But i am using XMLTextWriter that does not allow me to write tag data piece by piece. I have to have all the data and then write it to tag.
Any suggestions on how to handle this effectively will be appreciated.
Thanks,
cw

if you are just saving binary to XML you'll double the size of your data. If you encode it to base64 it'll only be about 4/3 the orginal size, but with conversion overhead.
Why do you need 8MB of binary data in XML anyway? To me it sounds like a design flaw not a memory issue.

I actually do encode to base64. It does not even get that far as it is stuck reading all the data from the file.
The reason i need to do it this way is because another application creates this data(video) and dumps it to a folder.
My application has to read it in, and put in an XML tag along with other data pertaining to it.
Any ideas to make this process better from a bandwidth perspective?

I have an app that uses filewatcher to monitor a directory. When a file gets in the directory it reads it, pulss out the jpeg and other data perfectly. Now i would like to display this data on the screen. I have created a picture control and some text controls to dsiplay this data. Anyone have some guidance or good source examples on how to do this?

You can use a WebBrowser control to show both images and text.

Jaime.
