  • How to delete a user in MSCRM 4.0

    - by Chris Richner
    Do you know of a way to get rid of CRM User accounts in MSCRM 4.0? After some user accounts have been deleted in AD we're faced a lot of issues while importing the organisation to another server stating that there are issues with the user mapping. What kind of idea is behind the fact that no user accounts can be deleted from the crm installation? Is there any tool or undocumented Webservice API call to get rid of crm users? Thanks for sharing yours insights

  • Flex - communicating between Itemrenderes in a single row.

    - by TheCoolestSid
    Hi, I have a datagrid with an XML object as dataprovider. There are 2 columns in the datagrid which have comboboxes as their itemrenderers. The rendereriseditor property is also marked true. These itemrenderers are defined in their own mxml files. What i want is if the user selects a particular item in the combobox, say NA, then the value of the other combobox should also become NA. How can i achieve such a behavior? Thanks Sid

  • WPF/MVVM: Delegating a domain Model collection to a ViewModel

    - by msfanboy
    A domain model collection (normally a List or IEnumerable) is delegated to a ViewModel. Thats means my CustomerViewModel has a order collection of type List or IEnumerable. No change in the list is recognized by the bound control. But with ObservableCollection it is. This is a problem in the MVVM design pattern. How do you cope with it?

  • In Subversion, I know when a file was added, what's the quickest way to find out when it was deleted

    - by Eric Johnson
    OK, so suppose I know I added file "foo.txt" to my Subversion repository at revision 500. So I can do a svn log -v http://svnrepo/path/foo.txt@500, and that shows all the files added at the same time. What's the fastest way to find when the file was deleted after it was added? I tried svn log -r500:HEAD -v http://svnrepo/path/foo.txt@500, but that gives me "path not found" - perhaps obviously, because the file "foo.txt" doesn't exist at "HEAD". I can try a binary search algorithm going forward through revisions (and that would certainly be faster than typing this question), but is there a better way?

  • Math: How to sum each row of a matrix

    - by macek
    I have a 1x8 matrix of students where each student is a 4x1 matrix of scores. Something like: SCORES S [62, 91, 74, 14] T [59, 7 , 59, 21] U [44, 9 , 69, 6 ] D [4 , 32, 28, 53] E [78, 99, 53, 83] N [48, 86, 89, 60] T [56, 71, 15, 80] S [47, 67, 79, 40] Main question: Using sigma notation, or some other mathematical function, how can I get a 1x8 matrix where each student's scores are summed? # expected result TOTAL OF SCORES S [241] T [146] U [128] D [117] E [313] N [283] T [222] S [233] Sub question. To get the average, I will multiply the matrix by 1/4. Would there be a quicker way to get the final result? AVERAGE SCORE S [60.25] T [36.50] U [32.00] D [29.25] E [78.25] N [70.75] T [55.50] S [58.25] Note: I'm not looking for programming-related algorithms here. I want to know if it is possible to represent this with pure mathematical functions alone.

  • mysql: Average over multiple columns in one row, ignoring nulls

    - by Sai Emrys
    I have a large table (of sites) with several numeric columns - say a through f. (These are site rankings from different organizations, like alexa, google, quantcast, etc. Each has a different range and format; they're straight dumps from the outside DBs.) For many of the records, one or more of these columns is null, because the outside DB doesn't have data for it. They all cover different subsets of my DB. I want column t to be their weighted average (each of a..f have static weights which I assign), ignoring null values (which can occur in any of them), except being null if they're all null. I would prefer to do this with a simple SQL calculation, rather than doing it in app code or using some huge ugly nested if block to handle every permutation of nulls. (Given that I have an increasing number of columns to average over as I add in more outside DB sources, this would be exponentially more ugly and bug-prone.) I'd use AVG but that's only for group by, and this is w/in one record. The data is semantically nullable, and I don't want to average in some "average" value in place of the nulls; I want to only be counting the columns for which data is there. Is there a good way to do this? Ideally, what I want is something like UPDATE sites SET t = AVG(a*a_weight,b*b_weight,...) where any null values are just ignored and no grouping is happening.

  • Deleting object in function

    - by wrongusername
    Let's say I have created two objects from class foo and now want to combine the two. How, if at all possible, can I accomplish that within a function like this: def combine(first, second): first.value += second.value del second #this doesn't work, though first.value *does* get changed instead of doing something like def combine(first, second): first.value += second.value in the function and putting del second immediately after the function call?

  • Oracle Merge Rejection Row Count

    - by Andrew
    Given an Oracle Merge statement with a rejection limit, is there a shorthand way to identify how many rows were rejected, without being forced to query the rejection destination? The rejection destination has records pre-merge, so would currently have to be counted twice and the difference taken, but it seems like there should be a counter exposed, given that it has to be aware of whether it has exceeded the rejection limit.

  • Python: deleting rows in a text file

    - by Jenny
    A sample of the following text file i have is: > 1 -4.6 -4.6 -7.6 > > 2 -1.7 -3.8 -3.1 > > 3 -1.6 -1.6 -3.1 the data is separated by tabs in the text file and the first column indicates the position. I need to iterate through every value in the text file apart from column 0 and find the lowest value. once the lowest value has been found that value needs to be written to a new text file along with the column name and position. Column 0 has the name "position" Column 1 "fifteen", column 2 "sixteen" and column 3 "seventeen" for example the lowest value in the above data is "-7.6" and is in column 3 which has the name "seventeen". Therefore "7.6", "seventeen" and its position value which in this case is 1 need to be written to the new text file. I then need a number of rows deleted from the above text file. E.G. the lowest value above is "-7.6" and is found at position "1" and is found in column 3 which as the name "seventeen". I therefore need seventeen rows deleted from the text file starting from and including position 1 so the the column in which the lowest value is found denotes the amount of rows that needs to be deleted and the position it is found at states the start point of the deletion
