  • How can I hide tracing code in Visual Studio IDE C# ?

    - by Mark
    As I'm starting to put more tracing in my code, i'm realizing it adds a lot of clutter. I know Visual Studio allows you to hide and reveal code, however, i'd like to be able group code into "tracing" code and then hide it and reveal at will as i'm reading the code. I suppose it could do this either per file or per class or per function. Is there any way to do this? What do you guys do? Adding some clarification The hide current feature kind of allows you to do this except that when the code is hidden, you can't tell if its tracing or not. You also can't say "hide all tracing code" and "reveal all tracing code" which is useful when reading a function depending on what you are trying to do.

  • How to collect the new "Applications and Services Logs" found on Windows 7 or Windows Server 2008 us

    - by Mark
    In Windows Server 2008 and Windows 7 there are new Events categorized under "Applications and Services Logs". There is also a subfolder called Microsoft which has tons of subfolders as well. Is there any way to collect these events through WMI? For the regular "Windows Logs" such as Application and Security, it is possible to use the Win32_NTLogEvent WMI class in the cimv2 namespace. However, this class does not provide access to the new Microsoft event logs. Any ideas?

  • Memory problem with basic UITableView when scrolling

    - by Sheehan Alam
    I have a very simple UITableView that has 3 sections, and 3 rows per section. #pragma mark - #pragma mark UITableView delegate methods - (NSInteger)tableView:(UITableView *)tblView numberOfRowsInSection:(NSInteger)section { return 3; } - (UITableViewCell *)tableView:(UITableView *)tblView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tblView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell... return cell; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tblView { if (tblView == self.tableView) { return 3; } else { return 1; } } Everything shows up fine, but as soon as I scroll my application crashes and my debugger tells me: * -[ProfileViewController tableView:cellForRowAtIndexPath:]: message sent to deallocated instance 0x5ae61b0 I'm not exactly sure what I am doing wrong.

  • What is the best algorithm for this problem?

    - by mark
    What is the most efficient algorithm to solve the following problem? Given 6 arrays, D1,D2,D3,D4,D5 and D6 each containing 6 numbers like: D1[0] = number D2[0] = number ...... D6[0] = number D1[1] = another number D2[1] = another number .... ..... .... ...... .... D1[5] = yet another number .... ...... .... Given a second array ST1, containing 1 number: ST1[0] = 6 Given a third array ans, containing 6 numbers: ans[0] = 3, ans[1] = 4, ans[2] = 5, ......ans[5] = 8 Using as index for the arrays D1,D2,D3,D4,D5 and D6, the number that goes from 0, to the number stored in ST1[0] minus one, in this example 6, so from 0 to 6-1, compare each res array against each D array My algorithm so far is: I tried to keep everything unlooped as much as possible. EML := ST1[0] //number contained in ST1[0] EML1 := 0 //start index for the arrays D While EML1 < EML if D1[ELM1] = ans[0] goto two if D2[ELM1] = ans[0] goto two if D3[ELM1] = ans[0] goto two if D4[ELM1] = ans[0] goto two if D5[ELM1] = ans[0] goto two if D6[ELM1] = ans[0] goto two ELM1 = ELM1 + 1 return 0 //bad row of numbers, if while ends two: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[1] goto two if D2[ELM1] = ans[1] goto two if D3[ELM1] = ans[1] goto two if D4[ELM1] = ans[1] goto two if D5[ELM1] = ans[1] goto two if D6[ELM1] = ans[1] goto two ELM1 = ELM1 + 1 return 0 three: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[2] goto two if D2[ELM1] = ans[2] goto two if D3[ELM1] = ans[2] goto two if D4[ELM1] = ans[2] goto two if D5[ELM1] = ans[2] goto two if D6[ELM1] = ans[2] goto two ELM1 = ELM1 + 1 return 0 four: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[3] goto two if D2[ELM1] = ans[3] goto two if D3[ELM1] = ans[3] goto two if D4[ELM1] = ans[3] goto two if D5[ELM1] = ans[3] goto two if D6[ELM1] = ans[3] goto two ELM1 = ELM1 + 1 return 0 five: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[4] goto two if D2[ELM1] = ans[4] goto two if D3[ELM1] = ans[4] goto two if D4[ELM1] = ans[4] goto two if D5[ELM1] = ans[4] goto two if D6[ELM1] = ans[4] goto two ELM1 = ELM1 + 1 return 0 six: EML1 := 0 start index for arrays Ds While EML1 < EML if D1[ELM1] = ans[0] return 1 //good row of numbers if D2[ELM1] = ans[0] return 1 if D3[ELM1] = ans[0] return 1 if D4[ELM1] = ans[0] return 1 if D5[ELM1] = ans[0] return 1 if D6[ELM1] = ans[0] return 1 ELM1 = ELM1 + 1 return 0 As language of choice, it would be pure c

  • Safari Jquery Dialog and Ckeditor

    - by Mark Milford
    Hi I am using a CKEditor in a Jquery Dialog... and in Safari the first time it loads it works but each subsequent time it is blank and no buttons or anything else works in the ckeditor... I have looked at http://stackoverflow.com/questions/2539855/ckeditor-instance-in-a-jquery-dialog and added the suggested dialog-patch.js but it doesn't help $("#TextDialog").dialog({height:400,width:650, modal:true,closeOnEscape:true, autoOpen:false, open: function(event, ui) { $("#Text").ckeditor(); }, close: function(event, ui) { CKEDITOR.remove($("#Text").ckeditorGet()); }}); That is my code, and it works it all browsers (well Chrome, IE and FF) but not in Safari!

  • Reading in Russian characters (Unicode) using a basic_ifstream<wchar_t>

    - by Mark
    Is this even possible? I've been trying to read a simple file that contains Russian, and it's clearly not working. I've called file.imbue(loc) (and at this point, loc is correct, Russian_Russia.1251). And buf is of type basic_string<wchar_t> The reason I'm using basic_ifstream<wchar_t> is because this is a template (so technically, basic_ifstream<T>, but in this case, T=wchar_t). This all works perfectly with english characters... while (file >> ch) { if(isalnum(ch, loc)) { buf += ch; } else if(!buf.empty()) { // Do stuff with buf. buf.clear(); } } I don't see why I'm getting garbage when reading Russian characters. (for example, if the file contains ??? ??? ???, I get "??E", 5(square), K(square), etc...

  • Stop propagating deletes

    - by Mark
    Is it just me or is anyone else finding EF very difficult to use in a real app :( I'm using it as the data layer and have created custom business objects. I'm having difficulty converting the business objects back to EF objects and updating/adding/deleting from the database. Does anyone know a good, simple example of doing this? Actually the current problem that's driving me nuts is when I delete something EF tries to delete other related stuff as well. For example, if I delete an invoice it will also delete the associated customer! Seems odd. I can't figure out how to stop it doing this. // tried: invoiceEfData.CustomerReference = null; // also tried invoiceEfData.Customer = null; context.DeleteObject(invoiceEfData); context.SaveChanges(); // at this point I get a database error due to it attempting to delete the customer

  • Django stupid mark_safe?

    - by Mark
    I wrote this little function for writing out HTML tags: def html_tag(tag, content=None, close=True, attrs={}): lst = ['<',tag] for key, val in attrs.iteritems(): lst.append(' %s="%s"' % (key, escape_html(val))) if close: if content is None: lst.append(' />') else: lst.extend(['>', content, '</', tag, '>']) else: lst.append('>') return mark_safe(''.join(lst)) Which worked great, but then I read this article on efficient string concatenation (I know it doesn't really matter for this, but I wanted consistency) and decided to update my script: def html_tag(tag, body=None, close=True, attrs={}): s = StringIO() s.write('<%s'%tag) for key, val in attrs.iteritems(): s.write(' %s="%s"' % (key, escape_html(val))) if close: if body is None: s.write(' />') else: s.write('>%s</%s>' % (body, tag)) else: s.write('>') return mark_safe(s.getvalue()) But now my HTML get escaped when I try to render it from my template. Everything else is exactly the same. It works properly if I replace the last line with return mark_safe(unicode(s.getvalue())). I checked the return type of s.getvalue(). It should be a str, just like the first function, so why is this failing?? Also fails with SafeString(s.getvalue()) but succeeds with SafeUnicode(s.getvalue()). I'd also like to point out that I used return mark_safe(s.getvalue()) in a different function with no odd behavior.

  • Algorithm to aggregate values from child tree nodes

    - by user222164
    I have objects in a tree structure, I would like to aggregate status information from children nodes and update parent node with aggregated status. Lets say node A has children B1, B2, and B1 has C1, C2, C3 as children. Each of the nodes have a status attribute. Now if C1, C2, C3 are all complete then I would like to mark B1 as completed. And if C4, C5,C6,C7 are complete make B2 as complete. When B1 and B2 are both complete mark A as complete. I can go through these nodes in brute force method and make updates, could someone suggest an efficient algorithm to do it. A { B1 { C1, C2, C3}, B2 { C4, C5, C6, C7} }

  • .NET: Allow NULLS in DB fields?

    - by mark smith
    Hi there, I have the task of re-factoring an SQLServer DB.... A lot of the tables and columns "ALLOW NULLS", Is this good practice... I seem to remember the authour of CSLA.NET saying it was really bad practice to allow nulls in a DB... If this is the case, what are my alternatives? Remove all "ALLOW NULLS" from all columns.... and in numeric columns use a value of -1 for example?? I would really appreciate any input anyone has. I am currently using a Model (from entity framework) from my DB and the db columns that "ALLOW NULLS" are null ... and some of the stored procedures require that i have a default value... i.e. BOOLEAN require FALSE as default ... but it is null.. Well i don't want to stray from my original question, ALLOW NULLS are a bad thing from what i can gather .... so how do i fix this ? Any help really appreciated

  • How can I easily get a TextReader from an XDocument?

    Given an XDocument instance, how can I easily get a TextReader that represents that instance? The best I've been able to come up with is something like this (where xml is an XDocument instance): var s = new MemoryStream(); var sw = new StreamWriter(s); xml.Save(sw); sw.Flush(); s.Position = 0; TextReader tr = new StreamReader(s); However, this seems a little clunky, so I was wondering if there's an easier way?

  • How do chains work in Rainbow tables?

    - by James Moore
    Hello, I was wondering if should one could explain in detail how chains work in rainbow tables as though you would a complete novice but with relevance to programming. I understand that a chain is 16 bytes long. 8 bytes mark the starting point and 8 mark the end. I also understand that in the filename we have the chain length i.e. 2400. Which means that between our starting point and end point in just 16 bytes we have 2400 possible clear texts? What? How does that work? in those 16 bytes how do i get my 2400 hashes and clear texts or am i miss understanding this? Your help is greatly appreciated. Thanks P.s. I have read the related papers and googled this topic a fair bit. I think im just missing something important to make these gears turn.
