MsiGetSummaryInformation 始终返回无效参数错误
我正在尝试设置 模板摘要信息流中的属性,但无论我做什么,它都会失败。我可以从句柄读取该属性,但无法将其写回。
我想生成 MSI 的多语言副本,该副本是用英语构建的(烛光和灯光)。我能够替换所有表中所有相应的翻译数据;我唯一无法更改的是上面的 Template 属性。
我已经尝试了所有可以用来传递新字符串值的方法,但它总是说参数无效。 这是我用来执行相同操作的函数 (C#):
public Boolean ChangeTemplateSummaryProperty(String strLangID) {
IntPtr hSIHandle;
if (MsiError.Success == MsiInterop.MsiGetSummaryInformation(IntPtr.Zero, m_strMSIPath, 1, out hSIHandle))
{
VariantType vtType = VariantType.LPStr;
int iVal = 0;
FILETIME oFileTime;
oFileTime.HighDateTime = 0;
oFileTime.LowDateTime = 0;
int iValSz = 0;
MsiError err = MsiInterop.MsiSummaryInfoGetProperty(hSIHandle, (uint)(SummaryInformationStreamProperty.Template),
out vtType, out iVal, out oFileTime, String.Empty, ref iValSz);
String strValue = new String('l', ++iValSz);
if (err == MsiError.MoreData)
{
err = MsiInterop.MsiSummaryInfoGetProperty(hSIHandle, (uint)(SummaryInformationStreamProperty.Template),
out vtType, out iVal, out oFileTime, strValue, ref iValSz);
}
else
{
Logger.LogError("Failed to get SummaryInformationStreamProperty.Template... err = " + err);
}
//I get the correct value here. as ";1033\0"
Logger.LogInfo("SummaryInformationStreamProperty.Template: " + strValue);
char[] arrNV = new char[strLangID.Length+2];
arrNV[0] = ';';
for (int i = 1; i < strLangID.Length + 1; i++) {
arrNV[i] = strLangID[i-1];
}
arrNV[strLangID.Length+1] = '\0';
String strNewVal = new String(arrNV);
//tried this, but fails.
//string strNV = ";";
//string strNV2 = strNV.Insert(1, strLangID);
//strNV2 = strNV2.Insert(strLangID.Length + 1, "\0");
err = MsiInterop.MsiSummaryInfoSetProperty(hSIHandle, (uint)(SummaryInformationStreamProperty.Template),
vtType, iVal, oFileTime, strNewVal);
if (err != MsiError.NoError)
{
Logger.LogError("Failed to set SummaryInformationStreamProperty.Template... err = " + err);
MsiInterop.MsiSummaryInfoPersist(hSIHandle);
MsiInterop.MsiCloseHandle(hSIHandle);
return false;
}
MsiInterop.MsiSummaryInfoPersist(hSIHandle);
MsiInterop.MsiCloseHandle(hSIHandle);
}
else
{
Logger.LogError("Failed to MsiGetSummaryInformation...");
return false;
}
return true;
}
I am trying to set the Template property in the Summary Information Stram but whatever I do, it fails. I can read the property from the handle but can't write it back.
I want to generate multilingual copies of the MSI which is built (candled and light) in English. I am able to replace all the respective translated data in all the tables; the only thing I can not change is the Template property above.
I have tried all the ways I can use to pass the new String value, but it always says invalid parameter.
Here's the function I am using to do the same (C#):
public Boolean ChangeTemplateSummaryProperty(String strLangID) {
IntPtr hSIHandle;
if (MsiError.Success == MsiInterop.MsiGetSummaryInformation(IntPtr.Zero, m_strMSIPath, 1, out hSIHandle))
{
VariantType vtType = VariantType.LPStr;
int iVal = 0;
FILETIME oFileTime;
oFileTime.HighDateTime = 0;
oFileTime.LowDateTime = 0;
int iValSz = 0;
MsiError err = MsiInterop.MsiSummaryInfoGetProperty(hSIHandle, (uint)(SummaryInformationStreamProperty.Template),
out vtType, out iVal, out oFileTime, String.Empty, ref iValSz);
String strValue = new String('l', ++iValSz);
if (err == MsiError.MoreData)
{
err = MsiInterop.MsiSummaryInfoGetProperty(hSIHandle, (uint)(SummaryInformationStreamProperty.Template),
out vtType, out iVal, out oFileTime, strValue, ref iValSz);
}
else
{
Logger.LogError("Failed to get SummaryInformationStreamProperty.Template... err = " + err);
}
//I get the correct value here. as ";1033\0"
Logger.LogInfo("SummaryInformationStreamProperty.Template: " + strValue);
char[] arrNV = new char[strLangID.Length+2];
arrNV[0] = ';';
for (int i = 1; i < strLangID.Length + 1; i++) {
arrNV[i] = strLangID[i-1];
}
arrNV[strLangID.Length+1] = '\0';
String strNewVal = new String(arrNV);
//tried this, but fails.
//string strNV = ";";
//string strNV2 = strNV.Insert(1, strLangID);
//strNV2 = strNV2.Insert(strLangID.Length + 1, "\0");
err = MsiInterop.MsiSummaryInfoSetProperty(hSIHandle, (uint)(SummaryInformationStreamProperty.Template),
vtType, iVal, oFileTime, strNewVal);
if (err != MsiError.NoError)
{
Logger.LogError("Failed to set SummaryInformationStreamProperty.Template... err = " + err);
MsiInterop.MsiSummaryInfoPersist(hSIHandle);
MsiInterop.MsiCloseHandle(hSIHandle);
return false;
}
MsiInterop.MsiSummaryInfoPersist(hSIHandle);
MsiInterop.MsiCloseHandle(hSIHandle);
}
else
{
Logger.LogError("Failed to MsiGetSummaryInformation...");
return false;
}
return true;
}

摆脱您正在使用的 MsiInterop,并使用 WiX 的 DTF 中的互操作。 Microsoft.Deploymnet.WindowsInstaller 命名空间有一个 SummaryInformation 类,该类公开读/写字符串 Template 属性。更好的对象模型和互操作,无需担心当前互操作让您处理的所有 P/Invoke 细节。
我现在在家,所以这里有一个代码片段:
注意 using() 子句的使用。 Database 类实现 IDisposable 接口并自动处理(双关语)清理所有那些讨厌的非托管句柄。
Get rid of the MsiInterop that you are using and use the interop found in WiX's DTF. The Microsoft.Deploymnet.WindowsInstaller namespace has a SummaryInformation Class that exposes a read/write string Template property. Way better object model and interop without worrying about all the P/Invoke details that your current interop makes you deal with.
I'm home now so here's a code snippet:
Notice the use of the using() clause. The Database class implements the IDisposable interface and automatically handles ( pun intended ) cleaning up all those pesky unmanaged handles for you.
