Go To End Of Loop If Condition Is Met?
Jun 20, 2010What 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:

SQL Group By With A Condition?
Aug 16, 2011Scenario: 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.
Sum With Multiple Condition?
May 14, 2010I 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.

C# - Using Codesnippet Until Condition Is True?
Nov 1, 2009I've got this function which converts wav files to mp3. I call this from my button_click handle. The thing is, when the conversion is started, the rest of the code in the button_click handler continue, while the conversion is happening in a different thread. Now, I need the rest of the code in the button_click handle so continue to try until a boolean is true, so that I know that the conversion is done before the rest of the code continues. I've tried using Do While but it didn't seem to do the trick. Perhaps it's just me though..

Search Within An Array With A Condition
May 7, 2012I have two array I'm trying to compare at many levels. Both have the same structure with 3 "columns.The first column contains the polygon's ID, the second a area type, and the third, the percentage of each area type for a polygone.So, for many rows, it will compare, for example, ID : 1 Type : aaa % : 100..But for some elements, I have many rows for the same ID. For example, I'll have ID 2, Type aaa, 25% --- ID 2, type bbb, 25% --- ID 2, type ccc, 50%. And in the second array, I'll have ID 2, Type aaa, 25% --- ID 2, type bbb, 10% --- ID 2, type eee, 38% --- ID 2, type fff, 27%.So, my function has to compare these two array and send me an email if there are differences.(I wont show you the real code because there are 811 lines). The first "if" condition is [code]I have two different layers in a geospatial database. Both layers have the same structure. They are a "spatial join" of the land parcels (55 000), and the land use layer. The first layer is the current one, and the second layer is the next one we'll use after 2015.So I have, for each "land parcel" the percentage of each land use. So, for a "land parcel" (ID 7580-80-2532, I can have 50% of farming use (TYPE FAR-23), and 50% of residantial use (RES-112). In the first array, I'll have 2 rows with the same ID (7580-80-2532), but each one will have a different type (FAR-23, RES-112) and a different %.
In the second layer, the same the municipal zoning (land use) has changed. So the same "land parcel" will now be 40% of residential use (RES-112), 20% of commercial (COM-54) and 40% of a new farming use (FAR-33).So, I wanna know if there are some differences. Some land parcels will be exactly the same. Some parcels will keep the same land use, but not the same percentage of each. But for some land parcel, there will be more or less land use types with different percentage of each.I want this script to compare these two layers and send me an email when there are differences between these two layers for the same land parcel ID.The script is already working, but it takes too much time. The probleme is, I think, the script go through all array2 for each row in array 1. What I want is when there are more than 1 rows with the same ID in array1, take only this ID in both arrays.Maybe if I order them by IDs, I could write a condition. kind of "when you find what you're looking for, stop searching when you'll find a different value?
