WINDOWS TIPS AND TRICK

1. Click the Windows 'Start' button and select 'All Programs.' Click 'Microsoft .NET 2010,' then click 'Visual Studio 2010' to open the software.
2. Click the 'File' menu item. Click 'Open,' and in the sub-menu of options, click 'Convert.' Double-click the VB6 project file in the dialog window to start the wizard.
3. Click 'Visual Basic .NET Upgrade Wizard' in the list of options. Click 'Next' in the first welcome window.
4. Select 'EXE' from the file type window. If the VB6 project is a DLL, choose 'DLL' instead and click 'Next.' The conversion window begins the upgrade.
5. Click 'OK' in the confirmation window. You can review the code changes in the files after the conversion wizard runs. Click 'Run' to execute the new code in the VB.NET debugger.

1. Create a new function that takes the URL as its single parameter, using this code:std::string GetUrl(const char *URL)
{
2. Insert this code to create a new constant buffer to store the size of the parts that make up your file:const int DownloadBufferSize = 1024;
3. Add this code to create a constant that stores errors, in case your program throws one:const std::string errorString = "ERROR";
4. Use the HINTERNET function of WinInet to open an Internet connection, before you attempt to download the file, by inserting this code:HINTERNET hInternet = InternetOpen("GINA: Version 0.1", INTERNET_OPEN_TYPE_DIRECT, NULL, 0,0);
if(hInternet == NULL){
return errorString;
}
5. Open the URL by using this code:HINTERNET hFile = InternetOpenUrl(hInternet, URL, NULL, 0, 0, 0);
if(hFile == NULL){
return errorString;
}
6. Create a buffer that holds file size by inserting this code:DWORD sizeBuffer;
DWORD length = sizeof(sizeBuffer);
7. Get the file size by using this code:bool succeeds = HttpQueryInfo(hFile, HTTP_QUERY_CONTENT_LENGTH | HTTP_QUERY_FLAG_NUMBER, &sizeBuffer, &length, NULL) == TRUE;
8. Create a new string to store the file by inserting this code:std::string downloadedContents = "";
9. Insert this code to set the download buffer and count the number of bytes your program downloads:char *downloadBuffer = new char[DownloadBufferSize];
DWORD bytesRead = 0;
do{
InternetReadFile(hFile, downloadBuffer, DownloadBufferSize, &bytesRead);
10. Append the contents of the download buffer to the file until the file is complete by using this code:downloadedContents.append(downloadBuffer, DownloadBufferSize);
}while(bytesRead != 0);
11. Close the WinInet handles and the program by using this code:InternetCloseHandle(hFile);
InternetCloseHandle(hInternet);
return downloadedContents;
}

1. Create a call to the DLL file. In this example, a call to a DLL that manages the hard drives on the machine is used. The following code creates a call to the file:
Declare Sub getdiskinfo Lib 'c:\myDLL' (ByVal drive As String, ByVal volume As String, free_space As Long)
2. Create variables to send to the function and variable that contains the return value. The following code is used to declare variables in Visual Basic:
Dim drive As String
Dim volume As String
Dim free As Long
Dim returnValue As Integer
3. Call the function and return a value. The following code illustrates how you use a DLL function in Visual Basic:
returnValue = getdiskinfo (drive, volume, free)
4. Display the result to verify your function results. The message box is used to test values in Visual Basic. The following code displays the return value from the 'getdiskinfo' function call:
MsgBox returnValue

Check the BIOS order
1. Reboot your computer system. Press the “Delete” key repeatedly until the BIOS screen displays.
2. Open the “Boot” menu. Check the order of the boot sequence list. Ensure that the hard drive that contains Windows, which is usually the C drive, is the first boot sequence listed.
3. Use the arrow keys to move the hard drive with Windows on it to the top of the boot list if it is not already in that order.
Replace the File
4. Load your PC with your Windows boot disk. Launch the repair or recovery setup.
5. Open the Command Prompt tool.
6. Paste the following command into the prompt and press “Enter:”D:\i386\hal.dl_ C:\windows\system32\hal.dll

1. Open a Visual Basic project. Double-click the "Progress Bar" control on the toolbar to add "ProgressBar1" to the form. Double-click the "Button" control to add "Button1" to the form.
2. Press "F7" to open the code window. Open the "Form1_Load" subroutine and type the following:ProgressBar1.Minimum = 0
ProgressBar1.Maximum = 5
ProgressBar1.Value = 0This code sets the starting values for the progress variable, as well as the minimum, maximum and current values for the progress bar. You can set a different maximum value depending on what you need the progress bar for.
3. Open the "Button1_Click" subroutine and type the following:If ProgressBar1.Value < ProgressBar1.Maximum Then
ProgressBar1.Value += 1
If ProgressBar1.Value = ProgressBar1.Maximum Then
MsgBox("Finished!")
End If
End IfWhen the user clicks the button, this code checks to see if the progress bar is less than maximum value. If so, it increments the value by one, causing the progress bar on the form to show greater completion as well. It then checks again to see if the value has reached the maximum. This way, when the progress bar does reach the max, you cannot increment the value any further and therefore you avoid an out-of-range error.

1. Understand terminology before choosing a .dll scan/repair software. .DLL refers to a collection of small files of code that serve as links between software and data. The registry, although used interchangeably with .dll, is different. The registry is essentially the nervous system for your computer. When you attempt to open a program, your computer searches the registry to find where the program is stored. The registry contains references to settings and values for the operating system, the programs, user profiles, document types, property sheet settings, system hardware and ports. If a computer begins to slow or crashes, it's usually because there's an error in the registry. Errors in the registry usually are caused by power outages, downloads and incomplete installation of software. In addition, registry errors can corrupt .dll files.
2. Note the error message, if you get one. A corrupted or missing .dll means that software you're requesting can't be found. For example, a win32.dll error message means the win32.dll file which involves data types, functions, objects, variables, constants, and classes that can be used to create applications for the Windows platform is missing or isn't retrieving data properly. Since the win32.dll defines how the operating system should operate, it's a critical file and needs to be replaced or repaired.
3. Install a top-rated program that scans, cleans and repairs the registry and any corrupted or missing .dll files. While there are free downloads on the internet, it's prudent to read reviews and pick a program based on functionality rather than cost. Reviewers rated RegCure the best in overall performance. For the average computer user, it's comprehensive and easy to use. You tell the program how often to run the scans; the program does the rest. Registry Easy won reviews in speed and its ability to repair the registry and .dll files. Error Fix was rated highly for its simplicity and ability to fix registry and .dll files.
4. Hire a computer software expert or find an online firm that fixes your registry and .dll errors remotely. Although the cost can be much greater than a package, many of these firms provide unlimited service for a one-year membership. After scanning, cleaning and repairing your computer, they will frequently include software that scans and repairs future errors automatically. Computer Geeks Online is just one of many remote computer repair firms. Before you settle on one, research reviews and ratings.
