No, unless by new you mean "less than ten years old"...ADODB supports parameterized queries and parameters for stored procedures, and has ever since I started using it (around 1998). It's also been known for at least that long that building query strings using the method you've been working with is unsafe in Web applications due to the possibility of a SQL injection attack. Additionally, this technique is prone to the very error you are now experiencing. Except for an ad-hoc query engine, I would not use the old technique. Whoever the VB programmer was, he shouldn't have been allowed to keep his queries in this form. As to resources, try searching for "SQL parameters" or "parameterized queries" in Google or Live Search and see what comes back.

Thanks to all who replied.
I found the error. my bad the code in VB had dbl quote then single quote. Apparently that has worked fine for years. In fact it worked fine on my development box. However once the code was starting through the conversion and being run on a test box we starting seeing the error.
I finally realized the the syntax should be single quote then dbl quote it all works fine.
This is a large scale project and these apps that I am upgrading only query for data in the Intranet. There is no writing back to the database.
Thanks for the info. I was really asking for some "best practices" info from you guys...thanks again

Take a steady grip with both your hands around the monitor.
Lift it up and move it closer to your face while twisting it from side to side.

I have another problem that has me perplexed.
I have a ToolStripStatusLabel on a StatusStrip. I change the BackColor
of the form that the StatusStrip is on. The ToolStripStausLabel's
background is painted in the form's BackColor.
I created an event handler for the BackColorChanged event on the
ToolStripStatusLabel and it is never fired.
I then created an event handler for the Paint event of the
ToolStripStatusLabel. It gets fired. I check the BackColor of the
ToolStripStatusLabel and it is the same as that for the StatusStrip.
But the background of the ToolStripStatusLabel is still painted in the
BackColor of the containing form.
So I am either missing something, or I have discovered a bug in the .NET
framework.
Has anyone encountered something like this before?

I am working on a application on .net 2.0. Sometime would update the app.config setting. However, my app do not get the updated app.config setting until i rebuild the app.
Do anyone tell me y and help me fix the problem. Thanks~~~

Its not a problem, thats how it works...
When your changing the app.config from visual studio your changing the one that sits with your code, when you build the app a copy of it is created and put with the exe so that it can access the app.config

Hi,
My problem is that I want to delete the nth line of a text file where n is the line number. I guess I could create StreamReader and use ReadLine() to read each line and store it in an array. Then I guess I could re-write the file using the array and omit the nth index.
But when I delete a line I don't want to renumber the subsequent lines. how I could do that?
Any guidance or help for this problem would be greatly appreciated.
Thanks,
Crul23

Renumber the subsequent lines? I don't follow that. Lines in a text file
are not numbered.
Otherwise I would suggest deleting the text in the line just leaving an
empty text line there. this would leave the same number of lines in the file, but delete the text of the line you want to delete.

I wouldn't do that if you could be passed a very large file. Better to write the lines to a temporary file as you go and then move/rename it to replace the original version when you're done.
You could even shift the content within the existing allocated space, but that might not be worth the trouble.
Crul23 wrote: I don't want to renumber the subsequent lines
Overwriting the existing line with SPACEs is simple.
Of course, if this is a class assignment, pick a way that will impress the teacher.

Hmm, this is a class assignment but I dunno if I'm suppose overwrite the line with spaces. Then again how else can the subsequent line numbers stay the same right? Hmm, I'll have to find out.
Also, what do you think would impress the teacher lol?

What line numbers are you talking about? Text files in Windows do not have line numbers. Some editors will display line numbers once you load a text file into them, but the operating system doesn't provide these.

If you don't know, you may want to ask your teacher, because we certainly can't tell you.

I have always added a "Settings" File to my project. Then used the Property Grid control to allow users to view/edit the Settings.
I'd like to allow for a cleaner configuration interface. (The property grid is just an table of all the options listed in alphabetical order) I'd like to be able to group options together and have things like checkboxes instead of True/False selections)
I have spent several hours searching for a good approach to binding windows forms controls to a Settings file or similar and surprisingly haven't come across anything quite like what i was looking for.
I did find some asp.net articles which allow for XMLDataSets to be binded to a form but this option doesn't appear to be available in C# Windows forms projects.
If someone could point me in the right direction, i'd really appreciate it.
Thanks in Advance,

Hi,
My application working fine in the dev environment.But in the testing /production environment
it is not working because that environment has only
windows server 2003
IIS
I have prepared a MSI which will automatically install .net2.0 framework
In my application I have Used some microsoft VC++ dll's also along with .net dll's.
Now Iam getting "<b>RUNTime Error</b>" pop-up screen message as below
" <b>The Application has been terminated in an Unusual Way</b>"
On googling i came to know that some dll's like msvcrt.dll of windows server 2003 has to be changed...But Iam not pretty sure about it..
In Production/test environment there is only framework installed ,but there is no visual studio installed on it.may be due that this error may occur...
So kindly post your suggestions and views to help me

I want to add item to my listbox if a mouse is clicked in the area between the two items. Is that even possible couldn't find anything on famous www.google.com.
|
|
|
|
|
Not sure, but have a test with MouseDown event, which will give you coordinates and GetChildAtPoint method.
The need to optimize rises from a bad design
|
|
|
|
|
If u want to add item from another list box then in mouse click event you copy that item to clipboard then paste to whr u wsant
|
|
|
|
|
Commonly used solution is making a context menu with add item. When a user clicks on list item and selects add you can prompt for information and add new listitem just before the one user clicked.
|
|

|

First of all thanks for answering to my question. I am already using context menu either (Addup or below). But I have realized, that I don't like this kind of feature. Wouldn't it be nice to display a blinking cursor (I-horizontal bar) within the listbox or may be in between the listbox items. Any insight would be kindly appreciated.

Is this a Windows or a Web application?
|
|
|
|
|
|
Since this is a Windows app, you can do it (would be impossible using the Web controls unless you developed a completely custom list control). In fact, the first reply you received mentioned the functions you need to do it.
