I had discovered where the issue was, I am using google Chrome and I had to clear the cache memory, and when I did that I had to check more checkboxes. I hope that my post help others. Thank you,

Hi, I am trying to add a style class to a blazor component, with isolated style method and when I add the style class on the blazor component located in the index.razor file, the blazor component disapears. I am doing that on a Webassembly Blazor project. So: I have followig files: -Index.razor, where I want to display the razor component

@page "/"

Index

Hello, world!

Welcome to your new app.

-DisplayComponent.razor, where the component is defined

DisplayComponent

how cool, it works

-DisplayComponent.razor.css where the style class is defined

.displayStyle{
margin:7px;
}

So please help me understading and implement this concept of isolated style. When I add class="displayStyle" on the display component in index.razor the content of the "DisplayComponent" disappear. I keep testing but I can't manage implementing a class on a blazor component with isolating style metgod. Give me some sugestions please. What I am missing? Thank you.

Yey Gerry, something like that I am doing now, for the moment I have started some blazor tutorials on microsoft site to see what blazor can do and what can I do with it and also I pay attention on some freelancing sites to see the demand.

When I finished to read the C# introduction book thats were the questions în my head, to start with UI windows programming or web developing? The ideea is that I've spended a lot of time with C++ and WINAPI without succeding entering in the freelanging programming market and now I wish to get the way that leads me to be able to work and make an income while I am adding more and more knowledge, I want to learn tools that help me not those that pushes me away from my goal. Thank you

Thank you for your responses. Blazor seems intresting because it is used for frontend and for backend development, this thing looks atractive I will take a look on it. Thank you for your time.

Hi, I want to become a freelancer programmer able to take jobs posted on freelancing sites or be part of a team where I can do at the begining small tasks for gaining experience. For that I have started to learn C++ and then WINAPI and when I was asking here questions about my WINAPI isues the experienced guys here told me that I am learnig an old tool and a very nice member here that helped me a lot recommended me .NET field with the book of Charles Petzold - .NET book zero, that was an excelent book because it dosen't entered in details. Now I have finished this book to, what tool you recommend me to learn next, what steps should I take that help me gaining experience and to be able to start working on real life project? I think that now would help me books or tutorials that are treating topics on surface. I want to mention that also I had installed, connected and tested a local database trough c++ and some years ago I installed an local apache server and played with html, php. Guide me please on what tools I have to learn next to be able to enter on the market, now I am working on another technical field and I want to gradually sustain myself from programming. Thank you în advance for your help.

Ok, tank you

Normaly this information should be in the installation folders of the C++ connector, in the headers files, and some of it, it is, but I just don' t know where to find definition of those methods, any way I supose that I will succed finally, but it would have been intresting to know how this method were coded. Or maybe those would be an waste of time or to complicate for my knowledge level.

Thank you for the link.

I had figured that if I know how this function is defined, I can extract more information about the conection, status of conection and other things that I am not aware, in addition I wanted to have a better overview on the subject.

I don't see where I am misunderstand the things but it appears to me as a declaration of a method. For example if we have a class defined like that:

class point{
public:
int x,y;
void set (int val_x, int val_y); // here the method declaration
};

void point::set( int val_x, int val_y) // here the method definition

x = val\_x;
y = val\_y;

}

void main()
{
point p1;

p1.set(10,2);    // here te call of the method

}

In the set method I have the parameters val_x and val_y, and I see in the definition of the set method the processes that implies val_x, and val_y, I see that val_x is attributed to x and so over, but in the connect method I don't see where hostName, userName and password are used. That it what I want to understand. Thank you,

Yes, but I don't know where to find the definition of this method. I don't find the code behind it.

When I installed Connector C++, there were unziped the headers that contains declarations of classes and functions. I suposed that is logical to find the declaration of these functions, clases constructors etc on those .h files. I found connect declaration in driver.h file:

class CPPCONN_PUBLIC_FUNC Driver
{
protected:
virtual ~Driver() {}
public:
// Attempts to make a database connection to the given URL.

virtual Connection * connect(const sql::SQLString& hostName, const sql::SQLString& userName, const sql::SQLString& password) = 0;

virtual Connection * connect(ConnectOptionsMap & options) = 0;

virtual int getMajorVersion() = 0;

virtual int getMinorVersion() = 0;

virtual int getPatchVersion() = 0;

virtual const sql::SQLString & getName() = 0;

virtual void setCallBack(sql::Fido_Callback &cb) = 0;

virtual void setCallBack(sql::Fido_Callback &&cb) = 0;

virtual void threadInit() = 0;

virtual void threadEnd() = 0;
};

And I found that the connection type(or class) of the connect defined in the connection.h file:

class CPPCONN_PUBLIC_FUNC Connection
{
/* Prevent use of these */
Connection(const Connection &);
void operator=(Connection &);
public:

Connection() {};

virtual ~Connection() {};

virtual void clearWarnings() = 0;

virtual Statement *createStatement() = 0;

virtual void close() = 0;

virtual void commit() = 0;

virtual bool getAutoCommit() = 0;

virtual sql::SQLString getCatalog() = 0;

virtual Driver *getDriver() = 0;

virtual sql::SQLString getSchema() = 0;

virtual sql::SQLString getClientInfo() = 0;

virtual void getClientOption(const sql::SQLString & optionName, void * optionValue) = 0;

virtual sql::SQLString getClientOption(const sql::SQLString & optionName) = 0;

virtual DatabaseMetaData * getMetaData() = 0;

virtual enum_transaction_isolation getTransactionIsolation() = 0;

virtual const SQLWarning * getWarnings() = 0;

virtual bool isClosed() = 0;

virtual bool isReadOnly() = 0;

virtual bool isValid() = 0;

virtual bool reconnect() = 0;

virtual sql::SQLString nativeSQL(const sql::SQLString& sql) = 0;

virtual PreparedStatement * prepareStatement(const sql::SQLString& sql) = 0;

virtual PreparedStatement * prepareStatement(const sql::SQLString& sql, int autoGeneratedKeys) = 0;

virtual PreparedStatement * prepareStatement(const sql::SQLString& sql, int* columnIndexes) = 0;

Yes, I have installed Connector C++ 8.0, in the link below it is explained that Conector C++ 8.0 supports "legacy C++ API based on the JDBC4", and there is an exemplified code where appear the "connect" statement, and I am not able to understand where is defined to see it's functions or more details. https://dev.mysql.com/doc/dev/connector-cpp/8.0/jdbc\_ref.html Thank you.

Hi, I want to work with a MYSQL database with jdbc using C++. I have started with connection and I saw in an example the following statement:

con = driver->connect("host", "usert", "password");

I found the connect declaration in the driver.h header as a connection type, but I don't know where to find the definition of the connect. Can anybody help me please with finding its definiton? Thank you,

Yes, My Listbox was empty and I was't observed that it was a Listbox. Thank you, see you soon with new topics.

Hmmm.... When I am creating a new empty project, when I choose to add a new .rc file, in this .rc file it's added automatically some code in that file, I was glad to see that, BUT!!! :mad:, it's appears that somewhere here was some problems or I wasn't pay attention on something, now I have copied exactly the content of the .rc file provided with the book, and now when I run the project, it's appearing an empty dialog box, it is emty, without the ListWiew, but it's a great start. I will put tomorrow the content of the file from the book because I am very tired now, and for shure we will see the critical diferences and for shure I will learn from that. Whoa, I am so glad, we will find and figure out what the clue is, thank you Richard for your patience. Thank you,

Can you please tell me where these adjustments were? So I can take a look at me? Teach me how to fix that problems, where to look. Because it can be from the dialog resource to not load properly the DialogBox and not to go to the Dialog procedure from that reason. Where can be the problem on me? ( I am using VS 2010 and I did't had problems with it until now). Thank you,

I would be grateful. Thank you,
