Of course! But I think the project is useful and will be helpful for those looking over this question in the future :)
If you are unable to deploy via web deploy (which can be a pain to configure), have you tried creating the web application and virtual director on the remote server, then enabling FTP and using FTP to deploy the site?
Surprisingly enough, this can also be quite tricky to set up. Why not give it a try and let me know if you have specific problems with it. This would get you up and running and take the stress off getting web deploy working
Thanks for the update, but actually I was wondering about the possibility of installing the IIS component automatically as part of say for example an Installshield Installation.
I think this will make sense - there's nothing *wrong* with what is created by default, all I need to do is add a few functions and an event handler, so augmenting what is created with an addition to the partial class would be just right - I suppose I could even write a Visual Studio addin to allow the augmentation to be invoked via a menu option or something. Thanks for the information!
I've updated the question :)
Thanks for this idea, I will look into creating content types for the assets for the customers and then a view for each customer, thanks for the feedback :)
Those are some very useful links, I think that they suggest that sub-sites per customer may not be appropriate in this case, along with Mark's solution below it looks like views per customer may be they way to go. I will continue with the research!
no probs - I get email notifications so I keep track of comments if you need to update the question ;)
In this case if the code works do it without, mention however that in more advanced scenarios you should use the stencil buffer to clip the reflecting plane (or the geometry of the reflecting surface). IF this helps out can you flag the solution as a correct answer :)
Try removing the stencil buffering options and see if it still works - it may be that you've inherited this code from an example that used the stencil buffer but doesn't any more. Typically it would be used to draw a stencil of the reflective surface so that the reflection when drawn is only drawn on the reflective surface - avoiding reflections that don't get 'cut off' when the mirror they are in ends.
No probs, I've updated the solution with an example, centralized 1024x768 div.
MS Access 2000: Table designer, choose the column and make sure 'Required' is set to 'No' - then you can use an int or a blank value (null!). If you have problems commiting - try using DBNull in the code :)
Right, well you do not use the index or primary key for this - if the primary key changes then it's not a key and it'll break database relationships. You need to add an extra column called 'row number' and keep this up to date yourself - if you delete a record with row number x, you must decrement every row number > x.
Why do you need the row number? It is generally not a sensible thing to store in a database, because the more records you have, the more processing is required to keep the row number up to date, this is a maintainance nightmare.
T-SQL has ROW_NUMBER()
but this will only number the results of a query. Are you sure you need the row number exactly? what are you using it for?
IT will indeed give a commit error - null is not a valid value for an integer.
Do you want it to be hidden if it is zero? Because this is entirely different!
If you need null as a value, you'll need to change your database to allow the column to be nullable.
An index doesn't have anything to do with deleted rows - it's just used as a unique key for rows in a table, only adding new rows needs to update the index - what are you expecting to happen when the row is deleted?
Row Number Index Example Column
1 1 Dogs
2 2 Cats
3 3 Fish
If you delete row 2, the indexes are (in order)
Row Number Index Example Column
1 1 Dogs
2 3 Fish
The indexes mustn't change! If they did, then anything that was using the index as a key (for example 'PetOwner' table has link to the table above) would be broken (e.g. a PetOwner of a Fish now owns something different!)
What is it exactly that you want the index to do? You can't use it as the 'number' of the row!
Use these attributes in the XAML datagrid definition:
Can you please tell us what the coil is in this context?
Cool glad you've got it working :)
I'll help just on my way home from work at the moment tho!
I noticed you posted that this wasn't working - we'll need more details to give you a better answer - what exactly does your data list contain?
If you provide code and more detail you're much more likely to get a decent answer ;)
That's more correct yes, although the post says he has 100 records using TOP 50 PERCENT is safer and will work when the number of records changes.
Perfect, thank you!
As an addendum, in most real-world applications the saving of a few clock cycles here and there through the way objects are allocated is negligent - the best approach to improve performance is to look at issues that cause bottlenecks:
* Disk Access
* Database transactions
* Manipulation of large data (images etc)
* Rendering of images
and so on - however, using the profiler is a good way to show where the bottlenecks are - it'll show you which functions are being spent the longest in and which areas can be improved.
For sure, although you'll need the right version of visual studio (Ultimate or Premium).
The task you are looking at is known as 'profiling', which involves running the application whilst visual studio (or another profiling tool) gathers low level data about how the CPU is being hit.
It's a complicated area, so the best I can do is suggest looking at:
and taking it from there :) Good luck!
OK, to each data member that is an object type we get 32 bits allocated (on a 32 bit system) or 64 bits allocated (on a 64 bit system). For each value type, we get the size of the value type. Therefore:
will give us 3 x 4 bytes for the strings (internally stored as a pointer to the string, i.e a memory address) and 64 bits (8 bytes) for the Int64. So we can roughly estimate this class will take up 20 bytes on the heap.
However, take a look at the class below:
In this case the someclass members are objects, so although each on takes up ~ 20 bytes the parent class needs only 8 bytes - enough to store two pointers.
creating an instance of parent takes up at least 8 bytes - even if the someclass members are not initialised.
in terms of time taken, the clock cycles used to allocate the memory are very few - allocating and freeing memory is generally a rapid operation.
we ourselves cannot enhance the speed of the compiler (it is very fast anyway) but you can certainly enhance the speed of the program by following some guidelines:
* create child classes only when needed. in the case of 'parent' above, don't created child1 and child2 in the constructor - create them only when required.
* make (very) small classes structures. if we have the class 'vector'
it is so small (~12 bytes) that the saving in storing as a pointer (12-4 = 8 bytes) is very small - if we're doing lots of work with vertex objects, manipulating, copying, passing them around, we will in general be faster defining them as 'structures' so that they are copied by value (i found this out the hard way with a c# openGL port).
also look into 'boxing' and 'unboxing' - there is an overhead in converting a value to an object and vice versa, i.e.
int i = 0;
in this case we have to 'box' i (which is a value) into an object to be passed to function.
I think understanding the concept of 'Inversion of Control' is crucial to this problem and other areas in general, so reading about this to get a better theoretical understanding would certainly be wise.
Also, as you mention it seems that there are mechanisms to do this in a low level way (TcpClient/TcpListener) as well as a more high-level way (self hosted services) - the requirements can determine the mechanism used, but the design should be handled after a thorough review of the requirements is made.
With these comments and the solution above I think I have plenty to go on - thank you very much for your help :)
Thanks Richard, this is exactly the information I needed :)
The XML is always created on windows, but might be stored on a unix machine, so the newlines thing shouldn't be a problem - setting up a unix server is what i'll do next, just wanted to get a rough idea of whether i'd be banging my head against a brick wall!
