• .NET Development Make mutiple threads, for loop?

  With an inputbox on a form the user is able set the number of threads to use. for 1 thread I've got this: Dim et1 As System.Threading.Thread = New Thread(AddressOf ThreadFunc) Dim t1 As Thread = New Thread(New ThreadStart(AddressOf ThreadFunc)) t1.Start() t1.Join() But if a user wants 20 threads how should i do this for loop Thanks for your reply! I got an error here: Dim threads As New Collection(Of Thread) -->Error 'Microsoft.VisualBasic.Collection' has no type parameters and so cannot have type arguments. How can i fix this With this code I am sending curl requests to a webserver. I'want to see how it handles many requests. For this i'm using threads to send multiple requests at the same time. ...Show All

• Smart Device Development GETTING MULTI-TASKING TO RUN

  i have a windows program and a C++ program. when i run the build.exe only the windows program runs. i am trying to enter the c++ program at  int main(), with no success. there is no c++.exe. there is a c++.obj, which does not help. i do not believe i need a thread. i do not believe spawning would work. the files are linked by x2 ,y2,messagechar. these links seem to work in the windows program, the c++ program does not run. statically after the compile all the variables are ok and data is passed from my c++ program to my windows program. i am trying to run c++ to see the dynamic operation. i bet the answer is run c++ except there is no exe file. i called main() from my windows program and my c++ file still does not ...Show All

• Visual Studio Team System So why build creation wizard doesn't let me attach tests?

  When I create build though the Wizard and get to the tab where I can select tests to run - it desables Next button as soon as I check "Run Tests" checkbox. It allows we to select my only vsdmi but test list doesn't show in the box below. I've read some article that advices prior to this create test list with VSTS Test Edition - but it seems quite stupid! If I am Lead Developer who is in charge of builds - why do I need non-Developer edition And anyway - can I have both Editions on the same machine Can somebody clarify this In my opinion, Microsoft should consider doing away with the Role based versions of VS. Just have VS Professional, and VS Team Suite. Drop the cost of Team Suite to somewher ...Show All

• Visual C# Compare ArrayList

  Hello, I have 2 sorted array lists. e.g.  arrayList1 = a,b,c,d,e,f,h,k,l  and  arrayList2 = a,c,d,f,g,h,i,j ArrayList1 contains the list of strings that are to be compared against.  Unfortunately there are thousands of strings in each.  So I don't know if it would be any good doing something like; does arrayList[0] == arrayList[0]||arrayList[1]||.... (in a loop of course). Another thing, arrayList2 is getting its (distinct) data from a database so I can't really check it against arrayList1 there and then, as it would leave the connection open for longer... I don't know maybe this is an ok trade off I don't suppose there is an efficient arrayList1.compare(arrayList2) method out there   ...Show All

• Windows Forms Drag and Drop problem(I have the code thoe)

  Hey, For the image drag and drop stuff I ahve a little problem...I want it to drag and drop but I dont want it to totaly take the image out...So what I am trying to do is instead of making it so that when you drag and drop an image it goes that but the picturebox that you draged the image from will still have it's image in there...Here is the code: private void pictureBox2_DragDrop( object sender, DragEventArgs e) { // Display the image in the selected PictureBox control.

• Visual C++ STL Thread Safety

  So, I looked for STL thread safety, and there are only two hits:  One in Visual C++ Express Edition , and the other in Visual C# Language . Where's the best place to discuss MSVC 2005's STL thread safety -MM mmoo9154 wrote: For instance, it would be (fairly) trivial, and immensely useful if std::queue was safe to insert from one thread and extract from another without synchronization. Mixing synchronization with those containers would introduce a bucket of problems. It would make portable / semi-portable STL implementations a lot harder to maintain. How can one judge which synchronization approach is best fit for any use of say a queue While one user would like read ...Show All

• Microsoft ISV Community Center Forums To find Whether a value in a cell is pasted?

  Hi, Actually if we copy - paste a value of one cell into another, the format of the copied cell, like font,color, size etc, overrides that of the cell in which the value is pasted. Is there any way where we can prevent this. Thanks i think there are a no. of ways of doing it... 1) right-click on the cell that you wanna paste, then select "Paste Special", and in the Paste Special dialogue box select "Values" or "Formula". 2) when you select the cell you wanna copy, copy from the Formular bar (ie. highlight the text in the formula bar then CTRL+C) instead of hitting CTRL+C when the target cell is selected. ...Show All

• Visual C++ summing elements of a vector(class) with class elements

  Hi, I'm using Visual Studio 2005 and trying to use "accumulate" function in order to sum elements of type vector class. However, the elements of the vector in question have are objects, namely: class bond { public: double strength, prob; bond() : strength(0), prob(0) {} bond(double x, double y) : strength(x), prob(y) {} }; void main() { vector<bond> bond_array(N); // N: very large double sum_total //say the elements of vector bond_array are full with values ... sum_total=accumulate(bond_array.begin(), bond_array.end(), 0); //This command is incomplete, see the question. ... } What I'm trying to accumulate is actually ".prob" of all elements of type bond in vector, and the parameter sum_total will be assigne ...Show All

• Windows Forms Open winforms with Async threads

  Hi, On my application 13 forms, that do something on load (each form is doing something else), and I need to open them all on App load (I'm not showing them, just create instance): <Code=c#> form1 frmOne = new form1; frmOne.LoadData; form2 frmTwo = new form2; frmTwo.LoadData; </Code> I want to load all of them at the same time (each in seperate thread). How can I do this The splash screen will be the main UI when being displayed. Your real forms will only be loaded after the splash is gone. It's still sync. call. I don't see any advantage of using splash because your forms cannot be loaded from background per Peter's explanataion. Correct me if I'm wrong. Thanks, Alan ...Show All

• Internet Explorer Development IE7 and desktop icons

  I just installed Internet Explorer 7 today, which I guess is a.k.a. Windows Live . All of my fancy customized shortcuts on the desktop disappeared and each got replaced by the same generic windows icon. Right-clicking & changing the icons in properties no longer works. Also, when I create an internet shortcut while browsing, that creates a shortcut with that same generic icon (not even an explorer logo). Now my desktop is just one forest of identical icons. Anyone know how I can fix this I've wasted all day without success. Dave Don't take this personally, but this kind of "canned" response, not even related to the question matter is what really irritates a lot of people ab ...Show All
