I'm working on a problem where i have to allow a user to input a word or phrase and then determine if it is a palindrome (a words that reads the same forwards and backwards) . It also says that the program should use a Boolean-valued function procedure named IsPalindrome that returns the value True when the word or phrase is a palindrome and the value False otherwise.

I'm trying to identify if the input of a textbox is non numerical, which cannot be converted to an integer/double for calculation. I do this by converting the input1.text to ascii, and looking at the value to determine the type of input. My question is whether there is any way I can analyze the whole input character by character? Asc() only gives the ascii value of the first character, but what if the input is "9W" etc? Such inputs will pass my character test, but cannot be converted to an integer.
View 2 RepliesAlright. I have a project I need to complete by 11:00 am today. I need a program that will allow a user to input a phrase into a text box. Another text box to input a letter. Then I need the program to count how many times, the letter appears in the phrase. I have everything set up. I know how to count how many characters are in the string, but not how many designated letters there is.
View 5 RepliesI'm having a very difficult task here. I need to analyze a certain text and find the minimum number of characters it needs to become a palindrome. The text will not have any special characters or numbers, just alphabet letters. Now, I've made some progression and have tried a lot of situations correctly, but in some situations I've gotten wrong outputs on the MINIMUM number of characters needed. I've tested the below texts:

I am trying to make a program which goes through the HTML code of a page and then searches for a certain phrase. I have gotten up to the point of executing a search on a site and then dumping the html code of the body.How would I go about doing this?
The phrase I'm looking for is "<tr><td><a
href=javascript:d(87178)>Name of File</a></td><td>Date Submitted</td><td>Likelyness
to work(%)</td></tr>
All I would need to do is find the number inside of the parenthesis (87178) in this example and I THINK I'm good to roll, so how would I do that?

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now
I have an issue with an Office addin I'm working on, which is implemented for Office 2003 & 2007. The addin is written in VB.NET 3.5 using VSTO.The problem comes from some external code which automates a mail merge, opening the mail merge template, merging and then closing the template document. The close is done with this code:
objWord.Documents(sDoco).Close SaveChanges:=wdDoNotSaveChanges, OriginalFormat:=wdPromptUser
Because of some logic in my addin, instigated from the Interop.Word.Application.DocumentBeforeClose event, a message box is opened which prevents the Office document from closing, which breaks the automation.
Is there a way for me to determine the SaveChanges parameter (if any) on a Close within an Office.Interop.Word.Application event, such as DocumentBeforeClose? I'm trying to capture this parameter and determine if it's set to wdDoNotSaveChanges so that I can work around this problem.

Does anyone have any idea what might be useful. It was thinks of a listview bu i can't see that you can type into that.

View 2 RepliesI have a word document (word 2000) and a drop down form field with options A, B and C.If the user pics A, I wants to hide some text and show some other text. If they pick B, then hide something else, show something else, and so on.How does one do this?I assume I need to pass the form field contents to a procedure or macro and then go into If >Then font.hidden = true or something? I've identified the text to hide/show with bookmarks, so I think I can use the bookmark as a range to hide or show?
How do I pass the form field content to the procedure? Also, can I trigger the procedure once the user selects something in the drop down? Like kick a macro off I'm thinking?
