将Reg_SZ值转换为REG_EXPAND_SZ和REG_DWORD值 [英] Converting Reg_SZ values to REG_EXPAND_SZ and REG_DWORD values

问题描述

Hello Guys，



使用以下代码将值插入MSI数据库（注册表）

  private   void  button2_Click（对象发​​件人，EventArgs e）
 {
 字符串 Name1 = lblDName.Name; 
  String  Value1 = txtDName.Text; 
 
 字符串 Name2 = lblUnisntall.Name 
 字符串 Value2 = txtUninstall 。文本; 
 
  //  查询数据库 
 WindowsInstaller.View view = instDb.OpenView（  INSERT INTO Registry（Name，Value）VALUES（' + Name1 +  '，' + Value1 +  < span class =code-string>'））; 
 
 view.Execute（ null ）; 
} 
 
此代码正常工作，但在 MSI数据库中插入值后。 
创建了Value1和值  2   as  REG_SZ（ String ）
但 符合我的要求，
 Value1，应该是REG_EXPAND_SZ 
值 2 ，应该是REG_DWORD 
 
你能帮我吗在中将转换为我的代码，然后将插入 MSI数据库。 
 
干杯，

解决方案

也许你应该阅读文档 [ ^ ]在MSI的注册表中。

Quote：

值

此列是可本地化的注册表值。该字段为格式化。 如果该值附加到以下前缀之一（即＃％value），则按表中所述解释该值。请注意，每个前缀都以数字符号（＃）开头。如果值以两个或多个连续数字符号（＃）开头，则忽略第一个＃并解释值并将其存储为字符串。





前缀



含义



#x该值被解释并存储为十六进制值（REG_BINARY）。

＃％该值被解释并存储为可扩展字符串（REG_EXPAND_SZ）。

＃该值被解释并存储为整数（REG_DWORD）。

Hello Guys,

Am using the below code to INSERT values into MSI Database (Registry table)

private void button2_Click(object sender, EventArgs e)
        {            
            String Name1 = lblDName.Name;
            String Value1 = txtDName.Text;
            
            String Name2 = lblUnisntall.Name
            String Value2 = txtUninstall.Text;

            // query the database
            WindowsInstaller.View view = instDb.OpenView("INSERT INTO Registry (Name, Value) VALUES ('" + Name1 + "', '" + Value1 + "')");

            view.Execute(null);
        }

This code work properly, but after inserting values in MSI database. 
The Value1 and value 2 are created as REG_SZ (String)
but as per my requirement, 
Value1, should be REG_EXPAND_SZ 
Value 2, should be REG_DWORD 

Could you please help me in converting them in my code and then to insert into the MSI database.

Cheers,

解决方案

Maybe you should read the documentation[^] on the Registry table in an MSI.

Quote:

Value
This column is the localizable registry value. The field is Formatted. If the value is attached to one of the following prefixes (i.e. #%value) then the value is interpreted as described in the table. Note that each prefix begins with a number sign (#). If the value begins with two or more consecutive number signs (#), the first # is ignored and value is interpreted and stored as a string.


Prefix

Meaning

#x The value is interpreted and stored as a hexadecimal value (REG_BINARY).
#% The value is interpreted and stored as an expandable string (REG_EXPAND_SZ).
# The value is interpreted and stored as an integer (REG_DWORD).
