View 1 RepliesI have a dataset that pulls information about topics. However, I need to filter the information so i only get the topics with certain Topic Codes (These topic codes are in the form of an array).
Me.TblTopicsTableAdapter.Fill(Me.MainDataSet.tblTopics)Right, let me try and explain better.
I have an array named COURSE_Topics. This array contains topic codes as string elements.Currently, my table adapter query looks like this:
SELECT [Topic Code], TopicName, NoOfCourses, Duration, StartDate, EndDate, [Level] FROM tblTopics
At the end of that query i need to add a WHERE [Topic Code] = - then list of topic codes in the array.
This string:
<a href="viewtopic.php?t=4133849" class="topictitle">any</a>
I want to extract the id of the topic but fail ..
Can anyone tell me how to close a topic or how to stop replies?
View 1 RepliesI have read - recently - many topics concerning the connection of TCP/IP connecting versus using the old winsck connecting method.

I use DocTools to Create a Compiled HTML Help File. I want to link to a specific topic in the help file from my program, but the filenames of the html files are generated randomly.
Is there any way to open a CHM to a specific topic by name?
I created a wrapper for DocTools, so I could have the command line piped to a text box and then I could obtain the Topics from there and save them in an INI file that I read when I call the help, but I don't know how to pipe the command line to a textbox.

View 6 Repliescan anyone of u tell me how should i integrate three different modules of my project into one.specifically which all files i need to alter
View 1 RepliesI need a graphical front end for my College project. However the modules that perform the core task (facial feature extraction) have been written in C. This was because the company where I am working on this requires that I code in C. I need a front end to show the results to our teachers in college. Since I do not know anything on working with windows and controls in visual c++, I thought of using VB as I know this language well. What I want to know is how do I call these C functions from VB. Here are some details of my C code.
1. Most functions' return values are just for the purpose of error handling. The output is one or more of the arguments itself (I used pointers for this).
