• How do you specify a 64 bit unsigned int const 0x8000000000000000 in VS2008?

  - by Mark Franjione

  I read about the Microsoft specific suffix "i64" for integer constants. I want to do an UNsigned shift to a ULONGLONG. ULONGLONG bigNum64 = 0x800000000000000i64 >> myval; In normal C, I would use the suffix "U", e.g. the similar 32 bit operation would be ULONG bigNum32 = 0x80000000U >> myval; I do NOT want the 2's complement sign extension to propogate through the high bits. I want an UNSIGNED shift on a 64 bit const number. I think my first statement is going to do a SIGNED shift right. I tried 0x800000000000000i64U and 0x800000000000000u64 but got compiler errors.

• VS HTML Designer Tag Hierarchy Links. Broken in all versions including 2010-or is it me?

  - by George

  Should this bar on the HTML designer show the tag name? It sometimes does! Here's an image of what I referring to. I thought for sure it must be a bug but considering that I heard that MS was rewriting the editor (designer too?) I am starting to question whether I know how to use it!

• Switching between multiple reports (.rdlc) in a single report viewer

  - by UserNameHere

  I have 2 reports, "report1.rdlc" and "report2.rdlc" and I want to be able to swap betweent the 2 of them in a single report viewer ("rv_1"). I also have 3 buttons: btn_1 which does: rv_1.LocalReport.ReportEmbeddedResource = "Application1.Report1.rdlc" rv_1.RefreshReport() btn_2 which does: rv_1.LocalReport.ReportEmbeddedResource = "Application1.Report2.rdlc" rv_1.RefreshReport() btn_3 which does: dim rds as new ReportDataSource rds.name = rds.value = rv_1.reset() rv_1.LocalReport.DataSources.add(rds) rv_1.RefreshReport() Now no matter what I put for rds.name and rds.value it leaves me with "A data source instance has not been supplied for the data source 'dataSetName_TableName'. So my question is; what do I need to put there in order to get this to work correctly?

• Find completely commented files which are commented by /* */.

  - by Dave

  Similar to this question. I would like to find all commented files. But in my case /* */ is a possibility. Apparently when you write changes to a database project, dropped objects are only commented out instead of deleting the file. I would like to remove all of these commented out files from the project. Is is possible to find all files which start with /* and end with */?

• When debugging in VS 2008 why does the debugger land on a second return statement?

  - by Hellfire

  When debugging the following console program: class Program { static void Main(string[] args) { Console.WriteLine(DoIt(false)); Console.WriteLine(DoIt(true)); } private static Boolean DoIt(Boolean abort) { try { throw new InvalidOperationException(); } catch(Exception ex) { if (abort) { return true; } Console.WriteLine("Got here"); return false; } } } Why does the IDE land on the second return statement during the second call to DoIt()? The results of the execution is correct but the debugging experience is misleading. Is this a known issue? Is the behavior in VS 2010 the same?

• Why Resource (.resx) file added on merely changing Form size and on adding button which is not resou

  - by Muhammad Kashif Nadeem

  1- Resource files suppose to be added on adding some resource in application like image or audio or video etc. But if I just change size of form a .resx file under that particular form. Changing size of form does not add any resource so why this .resx file. 2- I dropped a button on form and a resource file is included again this button is not some kind of resource, it is object created and having information in designer file. 3- A resource file added on dropping button on form but if I delete this resource file and run application it compile and run with NO error and button is still there. If this button has any relation with resource file then there must by some kind of compile or runtime error AND if .resx file has nothing to do with button then why it was added? I am using VS 2008. Thanks in advance for the help

• Difficulty understanding behavior of free()

  - by Rasmi Ranjan Nayak

  int main() { int *ptr, **ptr1; ptr = (int*)malloc(sizeof(int)); ptr1 = (int**)malloc(sizeof(int)); free(ptr); *ptr = 12345; ptr1 = &ptr; //free(ptr); //**ptr1 = 23456; printf("%d \n", **ptr1); system("pause"); return 0; } How does *ptr store the value 12345, when the memory has already been freed? So, now ptr should be pointing to garbage. Why is this happening?

• Why this doesnt't work in C++?

  - by user3377450

  I'm doing something and I have this: //main.cpp file template<typename t1, typename t2> std::ostream& operator<<(std::ostream& os, const std::pair<t1, t2>& pair) { return os << "< " << pair.first << " , " << pair.second << " >"; } int main() { std::map<int, int> map = { { 1, 2 }, { 2, 3 } }; std::cout << *map.begin() << std::endl;//This works std::copy(map.begin(), map.end(), std::ostream_iterator<std::pair<int,int> >(std::cout, " "));//this doesn't work } I guess this is not working because in the std::copy algorithm the operator isn't defined, but what can I do?

• vcxproj file won't load into solution.

  - by John C

  We've just recently switched to VS 2010 and i had a solution that was working fine. This moring when i try to load the solution i get the error: "An item with the same key has already been added." This occurs when it is trying to load one of our main projects and it is not loaded. I assumed the problem was with my solution so i created a brand new empty solution and tried to load the same vcxproj and got exactly the same error. When i revert the project file to a previous version it works, so apparently it's something in the vcxproj file. However it also appears that i'm the only one in the office that is affected. So some combination of the vcxproj file and my computer seems to be the issue. Has anyone seen anything like this before? Any ideas on a solution? Thanks

• How to change the default "double click" action of a web service in a class library (VS2010)?

  - by JL

  I have a web service defined as follows, residing in a class library: [WebService(Namespace = "http://comp.com/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class SendingItems_new : System.Web.Services.WebService When I double click it, instead of going to code view, it shows the design view. I NEVER use design view, so how can I get it to open up code view instead, its very annoying having to flick from design view each time. Thank you
