• Visual C++ unexpected behavior with find_first_of

  I require specifically formatted text for some output logs.  One requirement is no padding on exponent fields ( E-002 vs. E-02).  I simply call find_first_of("E-0"), and use the resultant index to paste together two substrings.  I have found what seems to be random behavior with find_first_of.  Consider the following program that illustrates it.  I generate some random numbers and do my parsing and show some output: int _tmain(int argc, _TCHAR* argv[]) {   srand( time(NULL) );   for( int i = 0; i < 10; ++i ) {     float value = (float) rand() / (RAND_MAX * 10);     std::stringstream ss;     ss << std::scientific << std::uppercase;   &nb ...Show All

• .NET Development Access DataBase from two Computers at same time

  I have a simple VB program that access a SQL '05 Database. I can access the database fine from each computer individually, but when both programs are running and I try to update the database from the machine that contains the database I get a concurrency violation: the UpdateCommand affected 0 of the expected1 records. How do I get the database to accept Updates from both programs I have restrict access set to multi_user. I also noticed that if one application updates a record the second doesn't reflect the new data. That seems correct because i'm loading the data into a dataset which only holds the original data. Does anyone know of an example or a quick explaination of how to let the second application running know that the datab ...Show All

• Windows Forms Open winforms with Async threads

  Hi, On my application 13 forms, that do something on load (each form is doing something else), and I need to open them all on App load (I'm not showing them, just create instance): <Code=c#> form1 frmOne = new form1; frmOne.LoadData; form2 frmTwo = new form2; frmTwo.LoadData; </Code> I want to load all of them at the same time (each in seperate thread). How can I do this The splash screen will be the main UI when being displayed. Your real forms will only be loaded after the splash is gone. It's still sync. call. I don't see any advantage of using splash because your forms cannot be loaded from background per Peter's explanataion. Correct me if I'm wrong. Thanks, Alan ...Show All

• SQL Server cube data

  after i process a cube, where does the cube(aggregrated) data reside There is a property of the Analysis Server called DataDir which points to something like C:\Program Files\Microsof SQL Server\MSSQL.<x>\OLAP\Data, but the exact path depends on how it was installed, if you right click on your server from SSMS, you can open up the properties window to confirm the exact location. But It depends what type of cube we are talking about... If it is a MOLAP cube, it is all stored in DataDir. If it is a HOLAP cube the aggregations are stored in DataDir, but the leaf level details are left in the relational source. If it is a ROLAP cube all the data is stored in the relational databas ...Show All

• Visual Basic Is a ColorMatrix the fastest way to edit bitmaps? (LockBits)

  I've made a function that makes bitmaps transparent via a ColorMatrix but now I'm wondering if that is truly the fastest way, because I can see that it takes a while (not that much, but enough to notice) to update the picture when I use a slider to adjust the transparency. Is there perhaps an imageformat that takes an alpha-value for the whole picture instead of per pixel, so that I don't have to use a colormatrix to go through every pixel to update the transparency Edit1: for example, setting the opacity of a form updates instantly, so how can I change a bitmap's transparency that fast in managed code - or is that just asking too much of VB Edit2: LockBits seems to promise better speeds - examples are welcome :) Edit3: okay, I tried b ...Show All

• SQL Server How to check is SSAS really clear the cache

  Hi,Does anyone know how to check if SSAS 2005 really clear the cache, after service restart or I run a ClearCache MDX scripts Thanks.J Lim Well, after service restart cache is obviously cleared, since the entire process was gone - so was all of its memory. If you are in doubt whether ClearCache really does it job, you can run simple MDX query to the cube - i.e. SELECT Measures.DefaultMember ON 0 FROM Cube, and watch profiler events - you will see that the data is coming from the disk. You can find some information about what events to watch and how to interpret them here: http://www.sqljunkies.com/WebLog/mosha/archive/2006/01/05/cache_prefetching.aspx HTH, Mosha ( http://www.mosha.com/msolap ) ...Show All

• Visual Studio How to catch .net 2003/5 solution tree drag and drop event

  I am using EnvDTE to build an addin for .net 2003/2005. I am trying to catch the drag and drop event of the solution tree for both file items and folders. From the EnvDTE module, I can't find anything which is really useful to do this. Also, found that IVsHierarchyDropDataTarget and IVsHierarchyDropDataSource interfaces in the VSIP provide support for drag and drop, but I have no idea to hook them up with the IDE's solution tree so that we could catch the event. Please help on this. Thanks very much. Ivan Hi Ivan, This particular interface is implemented by the hierarchy implementor.

• .NET Development Encrypted File + Append Encrypted Data - Do decrypt whole file

  Hi i've been having lots of headache with this, here's my scenario 1) i'm using log4net which i modified to have an EncryptedRollingFileAppender 2) it encrypts the data thru a CryptoStream and writes out the output to a file as binary 3) When the app is stopped, log4net is stopped and file is closed. When started again it will append the data in a similar fashion as 3. 4) I stop the app a 2nd time and now try to decrypt the entire log file. It will give me garbled data in between when it was stopped in 3 and started again. Cryptography used: Rijndael with fixed IV using CBC. I've tried all CipherBlockModes that Rijndael allows to no avail, even ECB still produces rubbish in between but the entire text is there, probably d ...Show All
