  • Cannot Debug Unmanaged Dll from C#

    - by JustSmith
    I have a DLL that was written in C++ and called from a C# application. The DLL is unmanaged code. If I copy the DLL and its .pdb files with a post build event to the C# app's debug execution dir I still can't hit any break points I put into the DLL code. The break point has a message attached to it saying that "no symbols have been loaded for this document". What else do I have to do to get the debugging in the dll source? I have "Tools-Options-Debugging-General-Enable only my code" Disabled. The DLL is being compiled with "Runtime tracking and disable optimizations (/ASSEMBLYDEBUG)" and Generate Debug Info to "Yes (/DEBUG)"

  • How to catch printf from a dll?

    - by Xarx
    I've got a C++ console application that uses a third-party dll (jvm.dll, indirectly) that uses printf to print various error messages (Java stacktrace). I need to catch these stacktraces to a string in order to process them further, or at least to see them printed on the console. The thing is that I see the stacktrace only when debugging my application in VisualStudio (VS 2010). When I run my application in the "normal way", i.e. from the command line, nothing is printed on the console. So VS is able to somehow interfere the java output and display it. I need to be able to do the same thing. I've already tried freopen(), but without success. Also, I've found this question on the same problem, but without a clear answer.

  • VB.NET ASP.NET Web Application woes (VS 2008)

    - by typoknig
    Hi all, I am making my first web application with ASP.NET and I am having a rough time. I have previously created the application I am working on as a Windows Form application and it works great, but I am having problems with the HTML side of things in the web application. My issues are pretty minor, but very annoying. I have worked with websites before and CSS, but as far as I can tell I do not have direct access to a CSS when creating a web application in VS 2008. My biggest issue is the positioning of components that I have dragged onto the "Default.aspx" form. For instance, how am I supposed to float a panel next to another one if I don't have a CSS, or how am I to correctly position a label?

  • Weird behavior of std::vector

    - by Nima
    I have a class like this: class OBJ{...}; class A { public: vector<OBJ> v; A(int SZ){v.clear(); v.reserve(SZ);} }; A *a = new A(123); OBJ something; a->v.push_back(something); This is a simplified version of my code. The problem is in debug mode it works perfect. But in release mode it crashes at "push_back" line. (with all optimization flags OFF) I debugged it in release mode and the problem is in the constructor of A. the size of the vector is something really big with dummy values and when I clear it, it doesn't change... Do you know why? Thanks,

  • How can I use my own connection class with a strongly typed dataset?

    - by Maslow
    I have designed a class with sqlClient.SqlCommand wrappers to implement such functionality as automatic retries on timeout, Async (thread safety), error logging, and some sql server functions like WhoAmI. I've used some strongly typed datasets mainly for display purposes only, but I'd like to have the same database functionality that I use with my class. Is there an interface I can implement or a way to hook my command/connection class into the dataset at design or runtime? Or would I need to somehow write a wrapper for the dataset to implement these types of functions? if this is the only option could it be made generic to wrap anything that inherits from dataset?

  • SSE SIMD Optimization For Loop

    - by Projectile Fish
    I have some code in a loop for(int i = 0; i < n; i++) { u[i] = c * u[i] + s * b[i]; } So, u and b are vectors of the same length, and c and s are scalars. Is this code a good candidate for vectorization for use with SSE in order to get a speedup?

  • how to access class and its functions from another class

    - by vbNewbie
    This is my first major application using multiple classes. It is written in vb and I know about creating objects of the class and using that instance to call functions of the class. But how do I create an object with constructors to allow another program written in C# to access my classes and functions and accept things from the program. Hope this makes sense.

  • .odx Files in BizTalk 2009 (VS2008 IDE) Fail to open. "Unspecified Error"

    - by AllenG
    Okay, I'm not sure if this is an SO question, or a ServerFault question, but I figured I'd post here first. I have a BizTalk project which works like a champ for its original design. It's been deployed and it's working fine. Today, I went in to add some new fuctionality by modifying one of my orchestrations. When I attempted to open it, I got a message which simply stated: "The operation could not be completed. Unspecified error." I've closed the IDE and re-opened; I've restarted the machine; I've even allowed Microsoft Updates to run and restart the machine. Everything else opens just fine (.xsd files, .btms, etc.) so it appears only to be the orchestrations which are failing. Has anyone ever encountered a similar issue and resolved it (short of reinstalling BizTalk/VS, or blowing the orchs away and rebuilding)? Any help would be appreciated.

  • Show bit Column as a checkbox column in unbound Datagridview

    - by Name.IsNullOrEmpty
    Dim Comp = From C In db.Table1 _ Select C.Completed, C.Taken, C.Namne Datagridview1.DataSource = Comp Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values. I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound. how can i change this in code at runtime

  • Debugging T4 Template in VS 2010 Crashes IDE

    - by Eric J.
    I'm trying to debug a slightly-modified version of the ADO.NET POCO Entity Generator template using the directions Oleg Sych published a few years back. I modified the DbgJITDebugLaunchSetting key as recommended. I get a dialog indicating that a user-defined breakpoint has been hit. However, rather than being presented with the option to start a new instance of VS 2010 to debug, the original instance of VS 2010 just crashes and auto-restarts. Is it possible to debug T4 templates with VS 2010?

  • error C2512 in precompiled header file?

    - by SoloMael
    I'm having a ridiculously strange problem. When I try to run the program below, there's an error message that says: "error C2512: 'Record' : no appropriate default constructor available". And when I double-click it, it directs me to a precompiled read-only header file named "xmemory0". Do they expect me to change a read-only file? Here's the segment of code in the file it directs me to: void construct(_Ty *_Ptr) { // default construct object at _Ptr ::new ((void *)_Ptr) _Ty(); // directs me to this line } Here's the program: #include <iostream> #include <vector> #include <string> using namespace std; const int NG = 4; // number of scores struct Record { string name; // student name int scores[NG]; double average; // Calculate the average // when the scores are known Record(int s[], double a) { double sum = 0; for(int count = 0; count != NG; count++) { scores[count] = s[count]; sum += scores[count]; } average = a; average = sum / NG; } }; int main() { // Names of the class string names[] = {"Amy Adams", "Bob Barr", "Carla Carr", "Dan Dobbs", "Elena Evans"}; // exam scores according to each student int exams[][NG]= { {98, 87, 93, 88}, {78, 86, 82, 91}, {66, 71, 85, 94}, {72, 63, 77, 69}, {91, 83, 76, 60}}; vector<Record> records(5); return 0; }

  • Seeking References To MSVC 9.0's C++ Standards Compliance

    - by John Dibling
    I "know" (hopefully) that MSVC 9.0 Implements C++ 2003 (ISO/IEC 14882:2003). I am looking for a reference to this fact, and I am also looking for any research that has been done in to how compliant MSVC 9.0 is with that version of the Standard. I have searched for and not been able to find a specific reference from MicroSoft that actually says something to the effect that MSVC implements C++ 2003. Some of the out-of-date documentation says things like "this release achieves roughly 98% compliance" (when referring to MSVC .NET 2003's conformance to C++ 1997). But I want a link to a document from MS that says "MSVC 9.0 implements blah," and another link to an independent group that has tested the conformance of MSVC 9.0. Do you know of any such links?

  • Why does this IF statement fail?

    - by ChosenOne
    If variable path is empty, and editor.Text is not empty, the SaveFileDialog should be displayed. Now, why on earth is this damn thing failing??? I have tried this with many different variations of code with the same result: FAIL: if(path.Length >= 1) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } At the top of code file I have: path = String.Empty; So why the heck it this failing every single time, even after trying all of the below variations? if(path.Length > 1) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } and if(String.IsNullOrEmpty(path)) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } and if(String.IsNullOrWhiteSpace(path)) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } This is making me very angry. How could this fail? Setting a break point reveals that path is definitely null/"".

  • Debugging a release version of a DLL (with PDB file)

    - by Martin
    If I have a DLL (that was built in release-mode) and the corresponding PDB file, is it possible to debug (step-into) classes/methods contained in that DLL? If so, what are the required steps/configuration (e.g. where to put the PDB file)? Edit: If have the PDB file in the same place as the DLL (in the bin/debug directory of a simple console test application). I can see that the symbols for the DLL are loaded (in the Output window and also in the Modules window), but still I cannot step into the methods of that DLL. Could this be the result of compiler optimizations (as described by Michael in his answer)?

  • web.config transforms not being applied on either publish or build installation package

    - by BenA
    Today I started playing with the web.config transforms in VS 2010. To begin with, I attempted the same hello world example that features in a lot of the blog posts on this topic - updating a connection string. I created the minimal example shown below (and similar to the one found in this blog). The problem is that whenever I do a right-click - "Publish", or a right-click - "Build Deployment Package" on the .csproj file, I'm not getting the correct output. Rather than a transformed web.config, I'm getting no web.config, and instead the two transform files are included. What am I doing wrong? Any help gratefully received! Web.config: <?xml version="1.0"?> <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <connectionStrings> <add name="ConnectionString" connectionString="server=(local); initial catalog=myDB; user=xxxx;password=xxxx" providerName="System.Data.SqlClient"/> </connectionStrings> </configuration> Web.debug.config: <?xml version="1.0"?> <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <connectionStrings> <add name="ConnectionString" connectionString="server=DebugServer; initial catalog=myDB; user=xxxx;password=xxxx" providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/> </connectionStrings> </configuration> Web.release.config: <?xml version="1.0"?> <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <connectionStrings> <add name="ConnectionString" connectionString="server=ReleaseServer; initial catalog=myDB; user=xxxx;password=xxxx" providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/> </connectionStrings> </configuration>

    Hi everyone, We need to install ASP.NET MVC on several developers machines with VS2010. Unfortunately the only files I can find in the Microsoft Download Center are labelled as ASP.NET MVC installer for VS2008. Can someone please point me in the direction of installer for VS2010, or can the VS2008 one also work for VS2010? Thanks, Dany.
