View 10 RepliesAsp.net - Converting Values Of Java.util.list To String Or Other Normal Format In Vb?
Mar 14, 2012in my application, I am pulling in items from a microsoft project file using mpxj - one of the items I need is the predecessors. The way I am able to pull the predecessor is using a build in function of mpxj which returns a type of java.util.list - I can save this to variable as an object, but I need to find a way to bring the data to a format I can easily use so I can store it into a database. Listed below is the line of code I am using to pull the predecessors from the project file.
Dim predecessors = task.getPredecessors
and here is the result when putting a tracepoint in to get the value of predecessors
[[Relation [Task id=4 uniqueID=45577 name=Standards Training - Round 2] -> [Task id=3 uniqueID=45576 name=Process Excellence Training]]]
Even if I could get the above as a string, I could work with it enough to get the data I need. The above example is where there is 1 item in the predecessor list, but sometimes there are multiple items. Here is an example of the tracepoint when there are multiple items.
[[Relation [Task id=63 uniqueID=45873 name=Complete IP Binder] -> [Task id=47 uniqueID=45857 name=Organizational Assessment]], [Relation [Task id=63 uniqueID=45873 name=Complete IP Binder] -> [Task id=49 uniqueID=45859 name=Document Deliverables]], [Relation [Task id=63 uniqueID=45873 name=Complete IP Binder] -> [Task id=56 uniqueID=45866 name=Infrastructure Deliverables]], [Relation [Task id=63 uniqueID=45873 name=Complete IP Binder] -> [Task id=58 uniqueID=45868 name=IT Deliverables]], [Relation [Task id=63 uniqueID=45873 name=Complete IP Binder] -> [Task id=60 uniqueID=45870 name=Organizational Deliverables]]]

View 2 RepliesCommunications :: Converting Numbers To Strings And Vice Versa
Oct 23, 2009When sending numbers over my server/client, I need to first convert them into strings and pack them together into larger strings, then deconvert them at the opposite end. I need to ensure that they occupy exactly the correct number of spaces in the string - for example I need an integer to use up 4 spaces. So for example, if I had a byte, then 2 integers, I need the first character to contain the byte, characters 2,3,4,5 to contain the first integer and 6,7,8,9 to contain the second integer. Then I can retrieve each number from the string using Mid(Position,Length) and convert it back to a number.I know how to convert bytes using chr and asc, but how would I convert my integers into my string and ensure they occupy the correct number of spaces in the string (and back).All the conversion methods I've looked don't seem to fit the bill. Will I need to write my own function to achieve this?

Converting Numbers To Roman Numerals And English Written Equivalents?

This is what I have so far, and I'm not completely sure if this is even right, but I can't figure much else out. I've talked to other people who know about this and they aren't sure how to go about it, and my book isn't a big help either.
I would really appreciate any and all help than anyone could give me. I just don't know what else to do and I've been stuck here for a few days trying to learn how to do this...

I.e. Once the main screen comes up it will show a formulae eg 3 + 3. After the forumale is shown the user will input the answer and then when they want to go to the next question that click the next button which inturn shows a different question if the answer is correct, if not it will stay on the same forumale. I would also like to add a skip button that will allow the user to skip the question if they cant figure it out.

View 7 RepliesDevelop An Application That Involves A Lot Of Tables And Maths?
Mar 7, 2011I would like to develop an application that involves a lot of tables and maths, and then displaying the results. I can visualize how this would work in SQL, as far as creating the stored procedures and tables required, however the front facing application would be a completely new experience to me.I would probably be sharing the built application with friends, but completely as a no profit tool. I assume that the developer edition of dot net is a suitable option? My main query is, is dot net really the best way to develop this tool? I have a strong feeling that I will not be able to use SQL as this would require a server to be run, and this is not practical. Can the tables be implemented into a DLL or similar to be used by the application for example?

Then below a little search button. And then when you click the button it will show a percentage of whom is most likely to win. Now I know that I would have to most likely enter something like

Heres the problem. The company has instituted a bonus program to give its employees an incentive to sell more. For every dollar the store makes in a four-week period, the employees receive 2 percent of sales. The amount of bonus each employee receives is based upon the percentage of hours he or she worked during the bonus period (a total of 160 hours). The Calculate button will determine the bonus earned by this employee, and the Clear button will clear only the name, hours-worked, and bonus amount fields. A Print button allows the user to print the form. Do not allow missing or bad input data to cancel the program; instead display a message to the user.
