  • Is it possible to design our own algorithm to create unique GUIDs?

    - by AKN
    GUID are generated by the combination of numbers and characters with a hyphen. eg) {7B156C47-05BC-4eb9-900E-89966AD1430D} In Visual studio, we have the 'Create GUID' tool to create it. I hope the same can be created programmatically through window APIs. How GUIDs are made to be unique? Why they don't use any special characters like #,^ etc... Also Is it possible to design our own algorithm to create unique GUIDs?

  • How do I fix my Unit Test to have global access to everything?

    - by SLC
    Usually when you add one (in Visual Basic), it pops up a message asking if you want to enable an option that lets the test access things like private methods etc. However, I am editing a solution that does not have this enabled. I'd like to enable it so my unit tests will work, but I can't find the setting. Can anyone tell me how to enable it after the project has been created?

  • how can I easily upload outlook contacts into my web application?

    - by Angela
    Hi, I am trying to find a way for our users to very easily upload their outlook contacts into our web application (mysql database). I'm not sure where to begin. I've seen various tools which are pretty complex. I am open to existing third-party solutions, but my hope is that there is something which is very simple to use or build. Thanks. PS: Ideally, it would not involve using visual basic.

    - by bdhar
    Conside the following code: int main() { signed char a = 10; a += a; // Line 5 a = a + a; return 0; } I am getting this warning at Line 5: d:\codes\operator cast\operator cast\test.cpp(5) : warning C4244: '+=' : conversion from 'int' to 'signed char', possible loss of data Does this mean that += operator makes an implicit cast of the right hand operator to int?

  • Should I bother with C++ or go straight to C#?

    - by Pat Riley
    I have been writing embedded C applications for almost 20 years. In the last few years I have written quite a few PC based GUI interfaces in Visual C so I could interface my embedded systems to a PC. Although my primary work will still be in deeply embedded C, I have finally decided to move my PC based tools into Ruby - (for quick scripting type stuff) and C++ or C# for GUI based interfaces and applications. Should I bother with C++ or just move straight to C#?

  • Explaining your system to a client

    - by Sir Graystar
    I'm currently developing a small Database Management System for a local company. How would you go about explaining how the system you have designed to a client? If they are non-technical and have no understanding of programming, how would you go about showing what the system will do and how it will do it? I guess some sort of visual representation of the system but this seems very patronising to me.

  • Best client for SVN / WIndows for READ ONLY ;)?

    - by TomTom
    Not interested in any source control OR shell integration. This is basically to make regular gets on certain third party archives.

Anyone a recommendation under those circumstances?

  • Is There A Way To Apply CODE Formatting To A VB.Net TextBox?

    - by Jeff
    I'm playing with a simple string replacement editor for editing VB.Net functions outside of VB. Is there a way to apply VB.Net code formatting to a string? For example. The txtboxCodeEntry looks like this: If strVar="dummy" then 1 else 0 Endif I would like it to "autoformat" to: If strVar = "dummy" Then 1 Else 0 End If The formatting would match whatever formatting VB.Net does when you're editing code in the Visual Studio IDE. Thanks.

  • Returning different data types C#

    - by user1810659
    i have create a class library (DLL) with many different methods. and the return different types of data(string string[] double double[]). Therefore i have created one class i called CustomDataType for all the methods containing different data types so each method in the Library can return object of the custom class and this way be able to return multiple data types I have done it like this: public class CustomDataType { public double Value; public string Timestamp; public string Description; public string Unit; // special for GetparamterInfo public string OpcItemUrl; public string Source; public double Gain; public double Offset; public string ParameterName; public int ParameterID; public double[] arrayOfValue; public string[] arrayOfTimestamp; // public string[] arrayOfParameterName; public string[] arrayOfUnit; public string[] arrayOfDescription; public int[] arrayOfParameterID; public string[] arrayOfItemUrl; public string[] arrayOfSource; public string[] arrayOfModBusRegister; public string[] arrayOfGain; public string[] arrayOfOffset; } The Library contains methods like these: public CustomDataType GetDeviceParameters(string deviceName) { ...................... code getDeviceParametersObj.arrayOfParameterName; return getDeviceParametersObj; } public CustomDataType GetMaxMin(string parameterName, string period, string maxMin) { .....................................code getMaxMingObj.Value = (double)reader["MaxMinValue"]; getMaxMingObj.Timestamp = reader["MeasurementDateTime"].ToString(); getMaxMingObj.Unit = reader["Unit"].ToString(); getMaxMingObj.Description = reader["Description"].ToString(); return getMaxMingObj; } public CustomDataType GetSelectedMaxMinData(string[] parameterName, string period, string mode) {................................code selectedMaxMinObj.arrayOfValue = MaxMinvalueList.ToArray(); selectedMaxMinObj.arrayOfTimestamp = MaxMintimeStampList.ToArray(); selectedMaxMinObj.arrayOfDescription = MaxMindescriptionList.ToArray(); selectedMaxMinObj.arrayOfUnit = MaxMinunitList.ToArray(); return selectedMaxMinObj; } As illustrated thi different methods returns different data types,and it works fine for me but when i import the DLL and want to use the methods Visual studio shwos all the data types in the CustomDataType class as suggestion for all the methods even though the return different data.This is illusrtated in the picture below. As we can see from the picture with the suggestion of all the different return data the user can get confused and choose wrong return data for some of the methods. So my question is how can i improve this. so Visual studio suggest just the belonging return data type for each method.
