C# :: Linking Progress Bar With Datagridview
Feb 25, 2014
I am running a windows forms project. on the form there is a datagridview, a progress bar, a textbox and two 2 buttons.
The two buttons are used to navigate through the records(one for next record and the other for previous record) the textbox displays the record that is being currently viewed.
How can I link the progress with the database or in this case the datagridview and when the next button is pressed it increments and when the previous button is clicked it decrements and also the progress to be fully filled when the last record is reached ?

Is there a way to make a circular progress bar in WPF without using another library or NuGet Package?
Like a tutorial on how to make it from scratch?
Right now, I'm using the existing ProgressBar UserControl but it looks horrible especially after I change the Foreground color from Green to DarkBlue.

Am developing windows forms application where in my form am fetching data into list from some object which takes around 2 minutes to complete processing so meantime i want to show progress bar before starting process till it ends with percentage. I have return a code to do multitasking but it is throwing error as "Cross-thread operation not valid: Control 'listOrg' accessed from a thread other than the thread it was created on".
private void btnOrg_Click(object sender, EventArgs e) {
try {
// To report progress from the background worker we need to set this property
backgroundWorker1.WorkerReportsProgress = true;

For a project I'm working on, I need to be able to download a file from an FTP server and store it to a predetermined location with a predetermined name. No user interaction should be needed. Because the file is rather large, and I need the main program to remain responsive, this is going to need a progress dialog.
I could write all this myself and use the MFC wininet wrappers (CInternetSession et al) to do the downloading, but... Explorer already has this, and IE has such a dialog also. It doesn't seem unreasonable to assume those dialogs are available via some API.
Is a "FTP download with dialog" available as a windows API, or do I really need to write all this myself ?

Why does my progressbar percentage text disapear when progressbar starts loading?? Am I missing out anything?
int percent = (int)(((double)(progressBar1.Value - progressBar1.Minimum) /

I'm having problems with progress bar when using a big number in set range. For numbers below 50000 it works very well but for big numbers like 100.000 it doesn't work, it makes 2-3 rounds of animation
Code:
int number= 50000; // 50k works well but if i put 100k it won't work (it will animate 2-3 rounds instead of complete one)
progressbar1.SetRange(0, number);
progressbar1.SetStep(1);
for (int i = 0; i < number; ++i) {
listcontrol1.InsertItem(i, _T("whatever"));
progressbar1.StepIt();
}
What's wrong with the code ?

I'm making a quiz game in c++. I've already completed it. But now I've thought of creating a profile and saving the progress for the user so when he enters his name the game continues frm where he had saved it.

I have a module that pings the network to find available devices using threading.
the money line:
var valids = range.AsParallel().AsOrdered().Where(ip => ip.Ping()).ToList();
The problem is, I need to display a progress bar while this function runs. I have the progress bar implemented with a background worker, but it won't update while the ping module is executing. I *think* it's because I'm using the available threads for the ping module.
When the user clicks a button, I need the ping module to run while the progress bar updates, or even just set IsIndeterminite to true. What would be the best way to accomplish this?

According to my project instructions, I have to make a "validation on the delete button, that before a record can be deleted it will check to see if the count of "In-Progress" orders for that product is 0. If it is greater than zero, it should not allow this record to be deleted."
So far I have on the code behind page:
protected void btnDeleteProduct_Click(object sender, EventArgs e)
{
DataView dv = (DataView)SqlOrders.Select(DataSourceSelectArguments.Empty);
[Coe].....
The professor said I have to: "As for getting the count, check your notes and book, specifically looking at SQL and the Aggregate functions. There is a function we talked about in class called "Count(OrderID)" and set the where clause to check for the productID.

What is the traditional way to monitor a blocking subroutine that is using a file stream as its input? That is, what is the traditional way to make a progress meter in the console?
Say I have a function that takes in a filestream and works with it. Suppose this file stream has a position and length property like in C# FileStream:
Code:
void sub (filestream file)
{
//read a bit of the stream, which advances stream cursor position
//do something
//repeat until all of file stream has been used up
}
Presumably the function is chomping along the file stream as it is doing some calculations serially on the file stream.Because the function is blocking, there is no way to access the file streams position and length in this thread. So naturally it seems like the best thing to do to monitor the progress of that function is to make another thread and pass it the file stream object as a parameter, and in this separate thread, monitor the distance between filestream's position and length to determine how much of the file stream has been used up, and every second or so output the amount of file stream used onto the console.

I am working on Explicit Linking of a DLL to an executable. But, when it comes to application, I have some troubles.
1) I try to export a class using C Language approach. (I would ask for other approaches later).
My dll project as follows:
dllmain.cpp
// dllmain.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"
BOOL APIENTRY DllMain( HMODULE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
[code]....
2) Related with the question above, what is the best way to provide a "pure" explicit linking? How can I explicitly link a dll without introducing the corresponding .lib and without including the dll's header file?

i am trying to write program that prints out full lyrics to 99 bear song. Hoping for explanation or anything
The output would have to look like:
99 bottles of beer on the wall, 99 bottles of beer.
Take one down and pass it around, 98 bottles of beer on the wall.
My try below:
Code: #include <iostream>
using namespace std;
int main()
{
for(int i=99; i>=0 ;i--)
cout << i <<""<< " bottles of beer on the wall, "<<i<<" bottles of beer."<<endl;
for(int j=98; j>=0 ;j--){
cout <<endl;
cout << "Take one down and pass it around," <<j<<" bottles of beer on the wall."<<endl;
}
return 0;
}

I am trying to refresh my memory here as I did some studies many years ago but the results elude me.Also todays c/c++ compilers may have better optimizations.Say I have a static library that includes three obj modules.Each of these object modules has a number of functions. These functions do not reference any other functions within the obj module.My main app links this library but only references one function from each of the object modules.
Question: Are the complete contents of each module linked into my main app or are todays linkers smart enough to just link the functions used?

I am forced to have the deceleration of a class template in the .h file.
See here: [URL] ....
This works perfectly fine, as long as i #inlcude the header file only in ONE .cpp file.
The moment i #inlude it in several .cpp files, i get LNK2005 already-defined errors.
a.obj : error LNK2005: "public: unsigned int * __thiscall theclass::themthod(void)" (?xxx@theclass@@QAEPAIXZ) already defined in b.obj
I would have assumed inclusion guards can protect me from this, but wrong.

I am writing a contact book program in C that will run in the terminal. I am going to create a file to store the data separately, but have run into a few question areas:
1) It has occurred to me that it might be more efficient to setup the program so that it sorts the contact info by info type rather than by running through an index of the contacts and then linking all of that contact's information to that index. So basically one part of the file would be phone numbers, the other contact names, and so forth with each piece of data linked to another piece within the data file that corresponds to the same contact. Am I wrong to think this is a more efficient way to set up the file?
2)How would you link the data information to other pieces of data corresponding to the same contact in C? My thought is to do it with pointers, but I didn't know if it were possible to have the pointers as I didn't know if the pointer would point "persistently" to the data once the file closed.As I felt this is a more "in general" question, I have chosen to omit my code from this post (especially since there is not much "meat" in it to speak of).

I have a libcx3d.a which contains my VrmlParser class and other classes which are used by VrmlParser. I have a main.cpp which does this :
VrmlParser vp = new VrmlParser();
double **VOB = vp.getVOB();
When I compile using g++ main.cpp -o main -L. -lcx3d, I get the following errors :
'VrmlParser' was not declared in this scope.
expected ';' before vp.
'vp' was not declared in this scope.
There is a header file called "VrmlParser.h" in the static library. Should I include this header file in main.cpp ? If so, will include "VrmlParser.h" work ? I have the .a and .cpp in the same directory. I can't find the header file for the static library.

I find myself in a position where I am repeating the same pattern of, write shared lib, compile, link shared lib, write app lib "sandbox" dependent on shared lib, write shared lib, compile, link, write...
At each level of dependency I have to carry over previously shared libs, search directories, etc. How to automate this process, so I spend less time linking after each layer?

I have built a static library that contains a macro. From a separate exe, I am calling this macro, but it doesn't work.
The compilation of the static library and that of the exe went okay.
Static lib contains just the macro definition.
Exe contains call to this macro.
Is there anything else that I need to do for this to work?

I have written a program that uses boost in visual studio 2012. The only boost library I used is filesystem by doing.
1)Properties->Linker->General and adding the path or the .lib to the additional dependencies. The libraries, link at compile time.However when i move the exe to a different computer, it doesn't work. Therefore the libraries were dynamically not statically linked. So my question is how do I statically link the filesystem library, so that i can include boost/filesystem.hpp in visual studio 2012?

I am having the issue of trying to call functions of a class through the header file.
Test.h
#ifndef TEST_H
#define TEST_H
class Test {
public:
void Hello();
[code]....
This code returns the error "undefined reference to 'Test::Hello()'"
All I am trying to do is call the Hello(); function in a seperate file.
