I am using a Webbrowser control to access the elements in an HTML page which contains a JavaScript link which when clicked, adds extra content to the page. This works fine in IE 7 and Firefox.I then want to access this extra content in my program. Having found the HTML element containing the link, I tried element.InvokeMember("click"). I have used this successfully with a submit-type link to login to the web site, but cannot get it to work with the JavaScript link. I also tried setting the focus to the link element and using SendKeys to send the ENTER key, but all to no avail. Nothing seems to happen. I don't see the extra content produced by the JavaScript, nor do I get an error.Here is an extract from the HTML, showing the relevant (I hope) code:

I have a workbook from an external party (let's call it wb_Client for reference purposes) containing two embedded combo boxes. The combo boxes show up in the formula bar as =EMBED("Forms.ComboBox.1",""). It seems that these combo boxes have their own name because in the spot where you normally see the cell ID (e.g. B14), I now see names. Combo box 1 is called "cmb_Fruit", and the second combo box is called "cmb_Country". Both combo boxes have drop down lists. The first combo box has the choices "Apple", "Orange" and "Pear". The second combo box has the choices "UK", "US" and "France".
Normally, if I open wb_Client (simply by double clicking on the file) the values of the combo boxes are "Apple" and "UK" by default. Suppose that, for example, cell "B10" represents the unit price, and that this number is 0.80. Next, if I change the combo boxes to "Pear" and "US", cell "B10" updates to 0.50. And the 0.50 is what I am interested in.
I only need this process to be automated. Thus, using my own workbook and some coding, I need to open wb_Client, set the value in the drop down list of combo box 1 to "Pear" and in the drop down list of combo box 2 to "US". Maybe I need some code to update/calculate the worksheet, and then grab the value from cell "B10". So the main problem is how to set the value in the combo boxes. How do I do this?
I Have a lot of numerical interval, never overlayed and not necessarly contigous, like this: 1-10, 11-56,90-134. how can I determine if a given interval, for example 45-90 is completely external to the other intervals?
View 3 RepliesI am embedding an xsd file into my console program so I can use it to parse XML files into a datatable which I then will parse and process into a text file and into a database. I have embedded the file and can access it by going to My.Resources.LinerTester. This will return a string, but in order to use it on the Dataset.ReadXmlSchema method I have to convert it to an XSD, otherwise I get an error saying invalid characters. How can I take the embedded resource and convert it to an XSD file? I know the XSD file works fine, if I read it from a location on the hard drive it will process the XML files into a dataset just fine, so the file itself is valid.
View 5 RepliesI have a DLL of a VB 6 Project that has one class and a form. The form is called from that class when its constructor is called. I made a DLL from the project, add that DLL is in my .NET project references. Now when I call that class DLL it gives the following error:

Which means the form is not opening.

The error I receive is showing ''saved_prac = cmd.ExecuteScalar()''..
First it brings the Message box - Only a numeric value is allowed in this field. When I OK it, then it brings another message box "error converting data type varchar to numeric". When you click OK the application crashes...
What is the correct syntax to go to the next sequence in a loop if certain conditions are met bypassing the contents.
I am using goto and inserting a line number which is probably not the best way.
I.E. My syntax:
For i = 0 to 100
If i = myvariable goto 100

Scenario: I need to create a report for the auditors for an ASP.Net application. I have a program that parses the XML of the web.config files in a directory for the authorization tag and creates a report providing which users have access to which folder in the site structure. The report is shown below.
UserName, Firstname, LastName, Directory, Roles, Access,
LastLoginDate
Problem: As you can see from the report some directories (the middle column with GISMO in it) show up twice, with both allow and deny for a user. I am wondering if there is a way to group the results in such a way that if there is a row that has allow for a directory then the deny's are not shown but otherwise they are.
Alternatively if this can be manipulated in VB.net/C# that is also an option. It comes back there and is pumped into an Excel spreadsheet.Edit: I should have explained better. I still need the deny rows to show if the user isn't allowed in the directory. But if they are allowed then there is no point showing the deny rows.
I am developing an application to my official use. In which I have one combo box for selecting the customerName.When I select the custName from the combobox I want to retrieve data from a particular field of a table and sum it within a selected date value. i.e: When the user selects a custName from the combobox the field within the date value should be summed up and grouped by custName. I think it is possible but I dont know how it is to be done.
