windows下Qt5.15调用Bartender打印报错

QAxObject btApp("BarTender.Application");
if (btApp.isNull()) {
setErr(err, "Cannot create COM object BarTender.Application (BarTender 2022 installed?)");
return false;
}

检查注册表

打开 regedit 搜索：

BarTender.Application
正常应该能在这些路径之一找到（取决于 32/64 位）：找到：HKEY_CLASSES_ROOT\BarTender.Application

但是使用PowerShell:执行

New-Object -ComObject BarTender.Application报错：

PS C:\Users\wangchen> New-Object -ComObject BarTender.Application
New-Object : 检索 COM 类工厂中 CLSID 为 {B9425246-4131-11D2-BE48-004005A04EDF} 的组件失败，原因是出现以下错误: 80040154
没有注册类 (异常来自 HRESULT:0x80040154 (REGDB_E_CLASSNOTREG))。

解决办法：

重新注册一下Bartender，使用管理员身份允许CMD

执行cd 安装目录；bartend.exe /Register后再次允许程序，运行成功。

导入模板，修改变量并打印流程：

const QString path = normalizePath(btwPath);
if (!QFileInfo::exists(path)) {
if (errorOut) *errorOut = "BTw not found: " + path;
return false;
}

QAxObject bt("BarTender.Application");
if (bt.isNull()) {
if (errorOut) *errorOut = "Failed to create BarTender.Application. Is BarTender 2022 installed?";
return false;
}
bt.setProperty("Visible", false);

QAxObject* formats = bt.querySubObject("Formats");
if (!formats) {
if (errorOut) *errorOut = "Failed to access BarTender.Application.Formats";
return false;
}

QAxObject* format = formats->querySubObject("Open(QString,bool,QString)", path, false, "");
if (!format) {
if (errorOut) *errorOut = "Failed to open format: " + path + " " + axLastError(formats);
return false;
}

if (!printerName.trimmed().isEmpty()) {
QAxObject* ps = format->querySubObject("PrintSetup");
if (!ps) {
if (errorOut) *errorOut = "Failed to access Format.PrintSetup";
format->dynamicCall("Close(bool)", false);
return false;
}
ps->setProperty("Printer", printerName.trimmed());
}

// Prefer NamedSubStrings (most common for variable placeholders).
bool anySet = false;
if (QAxObject* nss = format->querySubObject("NamedSubStrings")) {
for (auto it = namedValues.begin(); it != namedValues.end(); ++it) {
QAxObject* item = nss->querySubObject("Item(QString)", it.key());
if (item) {
format->dynamicCall("SetNamedSubStringValue(char *,char *)", it.key().toStdString().c_str(),it.value().toStdString().c_str());
anySet = true;
}
}
}
