仔细了解了下，InstallShield这几种定义的变量的用法：
1.String Tables里的变量：
Installation Information->General Information->String Tables 在设置的语言中:如Chinese(Simplified) 添加变量TestStr 并设置值。在Script中使用方法：
eg.
2.Property：
Behavior and Logic->Property Manager 添加变量如SoloProperty.在Script中使用语法：
eg.
function OnBegin()
STRING tempStr,tempStr2;
STRING svUsername[256];
NUMBER nBuffer;
begin
nBuffer = 256;
MsiGetProperty(ISMSI_HANDLE, "SoloProperty", svUsername, nBuffer);
MessageBox("SoloProperty Value is = " + svUsername, INFORMATION);
Exit;
end;
A useful function like this,:-):
Code:
prototype STRING GetValue(STRING);
prototype VOID SetValue(STRING, STRING);
function STRING GetValue(szName)
STRING szResult;
NUMBER nLength;
NUMBER nRetVal;
begin
nLength = 1024;
nRetVal = MsiGetProperty(ISMSI_HANDLE, szName, szResult, nLength);
if(nRetVal != ERROR_SUCCESS) then
MessageBox("Error retrieving value for: " + szName, WARNING);
endif;
return szResult;
end;
function VOID SetValue(szName, szValue)
NUMBER nRetVal;
begin
nRetVal = MsiSetProperty(ISMSI_HANDLE, szName, szValue);
if(nRetVal != ERROR_SUCCESS) then
MessageBox("Error setting value for: " + szName, WARNING);
endif;
end;
useage Code:
svMyValue = GetValue("SOME_PROPERTY");
SetValue("SOME_OTHER_PROPERTY", svMyValue);
3. Path variables:
Media->Path Variables
找到这句话：
Path variables used to represent source paths are not available at run time, only at build time.
