  • Winform Textbox CanGrow ?

    - by bochur1
    I don't find a CanGrow property on the Textbox control. This is common in some other controls, and what it does is expand the control to acomodate more data. Anyway to get this feature in the TextBox?

  • Multithreading A Function in VB.Net

    - by Ben
    I am trying to multi thread my application so as it is visible while it is executing the process, this is what I have so far: Private Sub SendPOST(ByVal URL As String) Try Dim DataBytes As Byte() = Encoding.ASCII.GetBytes("") Dim Request As HttpWebRequest = TryCast(WebRequest.Create(URL.Trim & "/webdav/"), HttpWebRequest) Request.Method = "POST" Request.ContentType = "application/x-www-form-urlencoded" Request.ContentLength = DataBytes.Length Request.Timeout = 1000 Request.ReadWriteTimeout = 1000 Dim PostData As Stream = Request.GetRequestStream() PostData.Write(DataBytes, 0, DataBytes.Length) Dim Response As WebResponse = Request.GetResponse() Dim ResponseStream As Stream = Response.GetResponseStream() Dim StreamReader As New IO.StreamReader(ResponseStream) Dim Text As String = StreamReader.ReadToEnd() PostData.Close() Catch ex As Exception If ex.ToString.Contains("401") Then TextBox2.Text = TextBox2.Text & URL & "/webdav/" & vbNewLine End If End Try End Sub Public Sub G0() Dim siteSplit() As String = TextBox1.Text.Split(vbNewLine) For i = 0 To siteSplit.Count - 1 Try If siteSplit(i).Contains("http://") Then SendPOST(siteSplit(i).Trim) Else SendPOST("http://" & siteSplit(i).Trim) End If Catch ex As Exception End Try Next End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim t As Thread t = New Thread(AddressOf Me.G0) t.Start() End Sub However, the 'G0' sub code is not being executed at all, and I need to multi thread the 'SendPOST' as that is what slows the application.

  • Compiler #defines for g++ and cl

    - by DHamrick
    I am writing a program that is cross platform. There are a few spots where I have to specify an operating system dependent call. #ifdef WINDOWS ..do windows only stuff #endif #ifdef LINUX ..do linux only stuff #endif Are there any preprocesser directives that get defined by the compiler so I don't have to explicitly define them when I use the command line compiler. ie. cl -DWINDOWS program.cpp or g++ -DLINUX program.cpp I realize I could easily write a makefile or have a shell/batch script that will do this automatically. But I would prefer to use the same ones as the compiler (if they exist) by default.

  • Is it possible for two VS2008 C# class library projects to share a single namespace?

    - by jeah
    I am trying to share a common namespace between two projects in a single solution. The projects are "Blueprint" and "Repositories". Blueprint contains Interfaces for the entire application and serves as a reference for the application structure. In the Blueprint project, I have an interface with the following declaration: namespace Application.Repositories{ public interface IRepository{ IEntity Get(Guid id); } } In the Repositories project I have a class the following class: namespace Application.Repositories{ public class STDRepository: IRepository { STD Get(Guid id){ return new SkankyExGirlfriendDataContext() .FirstOrDefault<STD>(x=>x.DiseaseId == id); } } } However, this does not work. The Repositories project has a reference to the Blueprint project. I receive a VS error: "The type or namespace name 'IRepository' could not be found (are you missing a using directive or an assembly reference?) - Normally, this is easy to fix but adding a using statement doesn't make sense since they have the same namespace. I tried it anyway and it didn't work. The reference has been added, and without the line of code referencing that interface, both projects compile successfully. I am lost here. I have searched all over and have found nothing, so I am assuming that there is something fundamentally wrong with what I'm doing ... but I don't know what it is. So, I would appreciate some explanation or guidance as to how to fix this problem. I hope you guys can help. Note: The reason I want to do it this way and keep the interfaces under the same namespace is because I want a solid project to keep all the interfaces in, in order to have a reference for the full architecture of the application. I have considered work arounds, such as putting all of the interfaces in the Blueprint.Application namespace instead of the application namespace. However, that would require me to write the using statement on virtually every page in the application...and my fingers get tired. Thanks again guys...

  • Sharing some info with all DLLs pulled into a process

    - by JBRWilkinson
    Hi all, We've got an Enterprise system which has many processes (EXEs, services, DCOM servers, COM+ apps, ISAPI, MMC snapins) all of which make use of many COM components. We've recently seen failures in some of the customer deployments, but are finding it hard to troubleshoot the cause. In order to track down the problem, we've augmented the entire source with logging statements where errors occur. In order to identify which logs came from what processes, the C++ logging code (compiled into all components) uses the EXE name to name the log. This is good for some cases, but not all - COM+ apps, ISAPI and MMC snapins all have system EXE names and the logs end up interleaved. I saw this post about shared data sections which might help, but what I don't understand is who decides what goes in the shared section. Is there any way I can guarantee that a particular piece of code writes into the shared section before anyone else reads it? Or is there a better solution to this problem?

  • Adding dlls in VS 2008

    - by Bart
    Hello, i would like to add some external .dll libraries e.g. glut32.dll (but it's only example) in vs 2008 using C#. Can you please tell me what should i do step by step? i am a little bit confused cause i found a lot of solutions to add dll files but they significantly differ.. some of them add dll's only using code, some using properties in vs, add references and in other tutorials there is about registering dlls in system. But how to put it all together? Regards!

  • Should I use a global var or call the function every time? C++

    - by extintor
    Im using: bool GetOS(LPTSTR pszOS) { OSVERSIONINFOEX osve; BOOL bOsVersionInfoEx; ZeroMemory(&osve, sizeof(OSVERSIONINFOEX)); osve.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX); if( !(bOsVersionInfoEx = GetVersionEx ((OSVERSIONINFO *) &osve)) ) return false; TCHAR buf[80]; StringCchPrintf( buf, 80, TEXT("%u.%u.%u.%u"), osve.dwPlatformId, osve.dwMajorVersion, osve.dwMinorVersion, osve.dwBuildNumber); StringCchCat(pszOS, BUFSIZE, buf); return true; } to get the windows version, and I am planning to use pszOS every a few minutes, Should I use pszOS as a global var or call GetOS() every time? What's the best option from a performance point of view.

  • Missing DLL Problem

    - by Liran
    Hi everyone. I have a C++ native application that was built under VS2005 (sp1),On machine A. (Debug Mode) Now,I need to run this application on a "clean" computer, Clean means it has no VS installed on. When i copy the runtime folder from machine A to the "clean" machine and try to activate the application it demands to reinstall the application. obviously missing DLLs are causing this problem cause on machine A the app works just fine, Is there any "clean" solution for this kind of problem besides gessing which DLLs are missing ? maybe a smart tool or installer that indicates which DLLs are missing at the runtime ? Thanks, Liran

  • How to merge on project / multiple files in VSS?

    - by Vijay
    I have VSS 6.0. I have branched my project so that I can do parallel development. I have 100s of files in folder/subfolders. I have changed some 10-20 files in multiple folders in ver 2 branch. Now I want to merge changes done in ver 2 to ver 1 branch. When I select the project merge branches option is not enabled. neither is it enabled when I select multiple files inside a folder. It's only enabled when one file is selected. Can I not merge on folder / multiple files in VSS 6.0. My thinking was when I do merge on project, VSS would pop up file names whenever there's a conflict (i.e files that are changed)

  • How do virtual destructors work?

    - by Prabhu
    Few hours back I was fiddling with a Memory Leak issue and it turned out that I really got some basic stuff about virtual destructors wrong! Let me put explain my class design. class Base { virtual push_elements() {} }; class Derived:public Base { vector<int> x; public: void push_elements(){ for(int i=0;i <5;i++) x.push_back(i); } }; void main() { Base* b = new Derived(); b->push_elements(); delete b; } The bounds checker tool reported a memory leak in the derived class vector. And I figured out that the destructor is not virtual and the derived class destructor is not called. And it surprisingly got fixed when I made the destructor virtual. Isn't the vector deallocated automatically even if the derived class destructor is not called? Is that a quirk in BoundsChecker tool or is my understanding of virtual destructor wrong?

  • MSVC 2003 doesn't see any definitions from a nested include file

    - by ezpresso
    I have a piece of code with COM class declaration as follows: #include "PathTypes.h" MIDL_INTERFACE("552C7555-0555-4444-BA86-56CF39AAFFFF") IPathCalc : public IUnknown { virtual HRESULT STDMETHODCALLTYPE GetLocation( /* [retval][out] */ GeoLocation* pLoc) = 0; virtual HRESULT STDMETHODCALLTYPE SetLocation( /* [in] */ GeoLocation* pLoc) = 0; ... }; Below is the contents of PathTypes.h file: #if !defined(PATHCALC_TYPES_INCLUDED) #define PATHCALC_TYPES_INCLUDED #include "libastro/AstronomyStructs.h" #endif And the libastro/AstronomyStructs.h from an external cross-platform library: #ifndef _ASTRONOMY_STRUCTS_INCLUDED #define _ASTRONOMY_STRUCTS_INCLUDED typedef struct { double lattitude; double longitude; } GeoLocation; ... #endif /* _ASTRONOMY_STRUCTS_INCLUDED */ When I'm trying to build this code with g++ everything goes well. That's not the case with MSVC 2003 which returns error C2061: syntax error : identifier 'GeoLocation'. Seems like MSVC doesn't "see" the definitions from the libastro/AstronomyStructs.h file. When I replace #include "PathTypes.h" with #include "libastro/AstronomyStructs.h" the code compiles without errors. How to make MSVC 2003 to actually "see" the definitions from the nested include files?

  • Is MS Reporting Services suitable for stand-alone reports?

    - by JMarsch
    Hello all: I work for a ISV. Our product can use both SQL Server and Oracle as its back-end server. It includes a number of reports (currently in Crystal). We are investigating moving to Micrsoft Reporting Services, but I'm beginning to think that it's a bad idea. We want for our reports to look and feel as though they are a part of our application, and we will not require SQL Server (the customer can choose Oracle). Although I see the reporting services supports a stand-alone mode (RDLC), the boundry between what requires SQL server and what doesn't looks extremely ambiguous. (example, the stand-alone report builder appears to require SQL Server, most of the documentation appears to be part of SQL Server's documentation) It looks to me like if I want to keep my application DB-agnostic, I had better steer clear of Reporting Services. Have I missed the boat here?

  • vs2008, opencv2.1,compile error in cxcore.hpp

    - by Long Gu
    Hi, gurus: I installed opencv2.1, made a new project (proj_A) using vs2008, used it for my computer vision tasks, it works fine. I copied an old project (proj_B, also made using vs2008) from other PC, compile it with ".h" and ".lib" files copied from opencv1.0 (which I did not install onto my PC), it compiles fine. I re-directed ".h" and ".lib" files in proj_B to opencv2.1 folders instead, compiled the proj_B, and then I got these errors from cxcore.hpp: class CV_EXPORTS RNG { public: enum { A=4164903690U, UNIFORM=0, NORMAL=1 }; // errors here, line 936 errors are: 5c:\opencv2.1\include\opencv\cxcore.hpp(936) : error C2143: syntax error : missing '}' before 'constant' 5c:\opencv2.1\include\opencv\cxcore.hpp(936) : error C2059: syntax error : 'constant' 5c:\opencv2.1\include\opencv\cxcore.hpp(936) : error C2143: syntax error : missing ';' before '}' 5c:\opencv2.1\include\opencv\cxcore.hpp(936) : error C2238: unexpected token(s) preceding ';' (400+ similar errors, but I believe the answer should be the same, so only list 1 set here) I compared setting for proj_A and proj_B, made them identical, and find no improvement. proj_A works well, proj_B refuse to compile. May I know what's wrong? Urgent, need to get it solved ASAP! Thanks a lot!

  • Git/SVN for asp.net development instead of VSS?

    - by jrutter
    At work, we are using ASP.net 2.0 and VSS. VSS is a beast, we are continually having issues with people checking out files and there is no branching - makes it crazy. I know SVN/GIT is mainly used by open source developers, are there any downsides to ASP.NET developers using it? I have been pushing for SVN internally, but am thinking GIT might also be a great option. Our team is spread across 3 continents.

  • Create a dynamic control and AddHandle WITH Values/Brackets

    Hi, it seems that adding for example a button Dim myButton as New Button and then addHandler to mySub("lol", 255) is not possible. Where mySub is Shared Sub MySub(byRef myString as string, myInteger as Integer) So: addHandler myButton.click, addressOf mySub("lol", 255) - returns an error saying it does not work with parentheses or whatever. I somehow see why this might not be possible, so I'm looking for a work-around on this problem. Please help _jakeCake

  • User Interface Diagram That is always reachable

    - by Fosa
    If you have to build a flow of a Use-case by drawing each Interface Diagram. Then you would start with a Diagram like say "login". But after the login page, no mather wich page you choose except the "logout" page, you always have your navigation bar right ? So all the options in the navigation bar? Like account page , personal page, etc... Do you have to make sure in your flow that in every diagram there is acces to the "accountpage" diagram ? Or do they have an other solution for that ? Thanx in advance
