After surfing around the net, I've found very little information regarding installation of VB6 on Windows 7. Most of the information out there is for Vista, and most of it is queries for assistance. You may be wondering why someone would want to utilize VB6 on a shiny new operating system like Windows 7. Or even Vista for that matter. There are about a bazillion legacy applications out there that have to be supported, and people like me who speak VB6 need to have the tools installed on our workstations in order to implement and test updates and such for these legacy applications. It also helps out when I need to squirt out a quick tool for use in my daily work. This process has been tested on Windows 7, both 3. Note: I've updated this process with information from the comments (below the post). If I've left something out, don't hesitate to point it out. Also - Thanks to all of you! Your comments and suggestions are much appreciated. Note 2: If you have a specific programming questions, might I please direct your attention to the VB6 forum? It's much easier to interact over there! Prerequisites: You need to do this stuff first. Turn off UAC. Create a zero- byte file in C: \Windows called MSJAVA. DLL. The setup process will look for this file, and if it doesn't find it, will force an installation of old, old Java, and require a reboot. By creating the zero- byte file, the installation of moldy Java is bypassed, and no reboot will be required. Install Direct. X 7. The process and files are available here. Install VB6 Common Controls, available here. Main Installation: Insert Visual Studio 6 CD. Exit from the Autorun setup. Browse to the root folder of the VS6 CD. Right- click SETUP. EXE, select Run As Administrator. On this and other Program Compatibility Assistant warnings, click Run Program. Click Next. Click "I accept agreement", then Next. Enter name and company information, click Next. Select Custom Setup, click Next. Click Continue, then Ok. Setup will "think to itself" for about 2 minutes. Processing can be verified by starting Task Manager, and checking the CPU usage of ACMSETUP. EXE. On the options list, select the following. Microsoft Visual Basic 6. Active. XData Access. Graphics. All other options should be unchecked. Click Continue, setup will continue. Finally, a successful completion dialog will appear, at which click Ok. At this point, Visual Basic 6 is installed. If you do not have the MSDN CD, clear the checkbox on the next dialog, and click next. You'll be warned of the lack of MSDN, but just click Yes to accept. Click Next to skip the installation of Installshield. This is a really old version you don't want anyway. Click Next again to skip the installation of Back. Office, VSS, and SNA Server. Not needed! On the next dialog, clear the checkbox for "Register Now", and click Finish. IDE Compatibility Setup. In order to prevent weird behavior of the IDE, such as sluggishness and/or lack of control placement/resizing outlines, you'll want to change these items. Using Windows Explorer, browse the location where you installed VB6. By default, the path is C: \Program Files\Microsoft Visual Studio\VB9. Right click the VB6. Click on the Compatibility tab. Place a check in each of these checkboxes. Run this program in compatibility mode for Windows XP (Service Pack 3)Disable Visual Themes. Disable Desktop Composition. Disable display scaling on high DPI settings. Service Pack 6 Installation: About the Authordwirch has posted a total of 1. You can find more information from dwirch by visiting http: //www.

How to Boost Database Development Productivity on Linux, Docker, and Kubernetes with Microsoft SQL Server 2. REGISTER > Environment: VC6 SP5, STLPort, Windows 2. SP2. This C++ tutorial is meant to help beginning and intermediate C++ programmers get a grip on the standard template class. The article was updated.). Rationale behind using vectors The final technical vote of the C++ Standard took place on November 1. However, significant parts of the Standard, especially the Standard Library, are still not very popular among many C++ users. A constant reader of Code. Guru's C++ forums will soon notice that many questions and answers still imply hand- crafted solutions that could be very elegantly solved by using the Standard Library. One issue that comes up very often is the use of C- style arrays, with all their problems and drawbacks. People seem to be scared of the standard. One reason might be that the Standard Library documentations are mostly pretty elliptic and esoteric. In this article, I will take vector and try to explain it in a way that is more accessible and understandable. I do not claim that this article is by any means complete. It is meant to give you a start in using vector and to help you avoid the most common pitfalls. We will start small and will not try to handle the topic very academically. Introduction to vector Vector is a template class that is a perfect replacement for the good old C- style arrays. It allows the same natural syntax that is used with plain arrays but offers a series of services that free the. C++ programmer from taking care of the allocated memory and help operating consistently on the contained objects. The first step using vector is to include the appropriate header: #include < vector> Note that the header file name does not have any extension; this is true for all of the Standard Library header files. The second thing to know is that all of the Standard Library lives in the namespace std. This means that you have to resolve the names by prepending std: : to them: std: :vector< int> v; For small projects, you can bring the entire namespace std into scope by inserting a using directive on top of your cpp file. This is okay for small projects, as long as you write the using directive in your cpp file. Never write a using directive into a header file! This would bloat the entire namespace std into each and every cpp file that includes that header. For larger projects, it is better to explicitly qualify every name accordingly. I am not a fan of such shortcuts. In this article, I will qualify each name accordingly. I will introduce some typedefs in the examples where appropriate—for better readability. Now, what is. std: :vector< T> v; ? It is a template class that will wrap an array of Ts. In this widely used notation, 'T' stands for any data type, built- in, or user- defined class. The vector will store the Ts in a contiguous memory area that it will handle for you, and let you access the individual Ts simply by writing v[0], v[1], and so on, exactly like you would do for a C- style array. Note that for bigger projects it can be tedious to repeatedly write out the explicit type of the vectors. You may use a typedef if you want. Do not use a macro!#define int_vec_t std: :vector< int> ; For the beginning, let's see what a vector can do for us. Let's start small and take the example of an array of integers. If you used plain arrays, you had either a static or a dynamic array. Let's do the same thing using a vector. As you see, vector combines the advantages of both the static and the dynamic array because it takes a non- const size parameter such as the dynamic one and automatically deletes the used memory like the static one. The standard vector defines the operator [], to allow a "natural" syntax. For the sake of performance, the operator [] does not check whether the index is a valid one. Similar to a C- style array, using an invalid index will mostly buy you an access violation. In addition to operator [], vector defines the member function at(). This function does the same thing as the operator [], but checks the index. If the index is invalid, it will throw an object of class std: :out_of_range. Depending on the implementation of the. C++ Standard Library you use, the above snippet will print a more or less explicit error message. STLPort prints the word "vector", the Dinkumware implementation that comes with Visual C++ prints "invalid vector< T> subscript". Other implementations may print something else. Note that vector is a standard container. The controlled sequence also can be accessed using iterators. More on iterators later in this article. For now, let's keep it simple. Now, what if you don't know how many elements you will have? If you were using a C- style array to store the elements, you'd either need to implement a logic that allows to grow your array from time to time, or you would allocate an array that is "big enough." The latter is a poor man's approach and the former will give you a headache. Not so vector. #include < vector>. In the previous example, push_back() appends one element at a time to the array. This is what we want, but it has a small pitfall. To understand what that is, you have to know that a vector has a so- called 'controlled sequence' and a certain amount of allocated storage for that sequence. The controlled sequence is just another name for the array in the guts of the vector. To hold this array, vector will allocate some memory, mostly more than it needs. You can push_back() elements until the allocated memory is exhausted. Then, vector will trigger a reallocation and will grow the allocated memory block. This can mean that it will have to move (that means: copy) the controlled sequence into a larger block. And copying around a large number of elements can slow down your application dramatically. Note that the reallocation is absolutely transparent for you (barring catastrophic failure—out of memory). You need to do nothing; vector will do all what that takes under the hood. Of course, there is something you can do to avoid having vector reallocate the storage too often. Just read on. In the previous example, we declared the vector using its default constructor. This creates an empty vector. Depending on the implementation of the Standard Library being used, the empty vector might or might not allocate some memory "just in case." If we want to avoid a too- often reallocation of the vector's storage, we can use its reserve() member function. The parameter we pass to reserve() depends on the context, of course. The function reserve() will ensure that we have room for at least 1. If the vector already has room for the required number of elements, reserve() does nothing. In other words, reserve()will grow the allocated storage of the vector, if necessary, but will never shrink it. As a side note, the following two code snippets are not the same thing. The first snippet defines a vector containing 1. If we hadn't integers but some user- defined class, vector would call the default ctor 1. The second snippet defines an empty vector, and then tells it to make room for 1. The vector will allocate enough memory to hold at least 1. If we had no integers, but some user- defined class, the second snippet wouldn't construct any instance of that class. To find out how many elements would fit in the currently allocated storage of a vector, use the capacity() member function. To find out how many elements are currently contained by the vector, use the size() member function. This will print. That means that the number of elements that can be added to a vector without triggering a reallocation always is capacity() - size(). Note that, for the previous example, only 0 is a valid index for array. Yes, we have made room for at least 1. Because int is a built- in type, writing all 1. Moreover, if we tried to access the other elements than the first using array. At a first sight, this may seem inconvenient, but a closer look reveals why this is so: If the vector contained objects of a user- defined class, reserve() wouldn't call any ctor. Accessing a not- yet- constructed object has undefined results and is a no- no in any case. The important thing to remember is that the role of reserve() is to minimize the number of potential reallocations and that it will not influence the number of elements in the controled sequence.
