我遇到的问题只发生在非常小的客户范围内,我想问一下你是否可以给我一个提示问题的提示。该计划适用于98%的客户。唉,我不可能与客户一起调试问题,因为他们对Windows和计算机的了解非常基础。我也不可能向他们发送多个版本的产品,因为他们甚至不知道如何安装软件(管理员会做所有的事情)。
首先,我即时翻译所有RT_STRING
资源,以便程序中的语言切换也会影响硬编码的内容,例如" Yes"," No& #34;,"取消"等,这只能通过编译2个EXE文件来实现。
代码(我试图尽可能多地留下不必要的东西,但由于我不知道问题出在哪里,我尽可能多地提供了bug的详细信息):

i: integer;
s: string;

const
FILE_ATTRIBUTE_NOT_CONTENT_INDEXED = $2000;
{$IFEND}
begin
// I copy all resources in a dummy DLL (without code), because
// 1) The resources are the only thing we need when changing the resource module
// 2) If the EXE code/debug sections are too long, BeginUpdateResource() will ruin the performance heavily
FTempFile := IncludeTrailingPathDelimiter(GetTempDirectory) + GetRandomString(8)+'.dll';
// Transfers all resources from ParamStr(0) into the dummy DLL at FTempFile
ReGenerateResourceFile(FTempFile);
// if necessary, remove readonly flag
SetFileAttributes(PChar(FTempFile), FILE_ATTRIBUTE_OFFLINE or
FILE_ATTRIBUTE_NOT_CONTENT_INDEXED or
FILE_ATTRIBUTE_TEMPORARY );
for i := 0 to Length(RTLResStringTranslationArray)-1 do
begin
s := Translate(RTLResStringTranslationArray[i].TranslationID);
if s <> '' then
begin
// Translate the string
UpdateResString(RTLResStringTranslationArray[i].ResStrDescriptor.Identifier, s);
end;
end;
LoadNewResourceModule(FTempFile):
end;
procedure ReGenerateResourceFile(OutputFile: string);
var
hUpd: Cardinal;
rs: TResourceStream;
fs: TFileStream;
begin
// As template we use a dummy DLL which contains no code.
// We will implement all resources from ParamStr(0) into it, before we translate the strings.
rs := TResourceStream.Create(HInstance, 'DUMMYDLL', 'DLL');
fs := TFileStream.Create(OutputFile, fmCreate or fmOpenWrite);
try
fs.CopyFrom(rs, rs.Size)
finally
rs.Free;
fs.Free;
end;
// Transfer resources from our EXE into the dummy DLL file
hUpd := BeginUpdateResource(PChar(OutputFile), true);
try
EnumResourceTypes(hInstance, @_enumResTypesProc, hUpd);
finally
EndUpdateResource(hUpd, false)
end;
end;

procedure UpdateResString(const AStringIdent: Integer; const ANewString: WideString);
var
ResData, TempData: TWordArray;
iSection, iIndexInSection: Integer;
i, iLen, iSkip, iPos: Integer;
begin
// Calculate the resource string area and the string index in that area

end;
// Put data behind strings into TempData
iSkip := 1{size} + ResData[iPos];
SetLength(TempData, Length(ResData) - (iPos + iSkip));
if Length(TempData) > 0 then
begin
CopyMemory(@TempData[0], @ResData[iPos + iSkip], Length(TempData)*SizeOf(TempData[0]));
end;
SetLength(ResData, iPos + (iLen + 1{size}) + Length(TempData));
// Overwrite string
ResData[iPos] := iLen;
Inc(iPos);
if iLen > 0 then
begin
CopyMemory(@ResData[iPos], @ANewString[1], iLen*SizeOf(ANewString[1]));
Inc(iPos, iLen);
end;
// Append TempData after our new string
if Length(TempData) > 0 then
begin

end;
CacheSet(iSection, ResData);
end;
type
TGlobalData = record
GlobalPtr: Pointer;
Length: integer;
end;
function LoadResourcePtr(hModule: HMODULE; restype, resname: PChar; wIDLanguage: WORD): TGlobalData;
var
hFind, hRes: THandle;
begin
result.GlobalPtr := nil;
result.Length := -1;
hFind := Windows.FindResourceEx(hModule, restype, resname, wIDLanguage);
if hFind = 0 then RaiseLastOSError;

if hres = 0 then RaiseLastOSError;

end;
function _enumResLangsProc(hmodule: HMODULE; restype, resname: PChar; wIDLanguage: WORD;
lParam: LongInt): BOOL; stdcall;
var
rs: TGlobalData;
begin
rs := LoadResourcePtr(hmodule, restype, resname, wIDLanguage);
UpdateResource(lParam, restype, resname, wIDLanguage, rs.GlobalPtr, rs.Length);
result := true;
end;
function _enumResNamesProc(hmodule: HMODULE; restype, resname: PChar;

lParam: LongInt): BOOL; stdcall;
begin
EnumResourceNames(hmodule, restype, @_enumResNamesProc, lParam);
result := true;
end;
{$R '..\dummydll\dummydll.RES'}
然后我使用等待表单:
unit Wait;
interface
uses
...
type
TWaitForm = class(TForm)
...
end;
var
WaitForm: TWaitForm;
implementation
{$R *.dfm}
...
end;
将通过动态显示表单来调用等待表单:
procedure ShowWaitForm;
begin
...
{ I use my own _CreateForm function because it solves many workarounds for
juicy stuff like half-modal windows (which can be hidden without user action),
miscellaneous deadlocks etc. and to allow the form to be shown in a shared PAS file
without the requirement to add it to every DPR file where the WaitForm API is used. }
WaitForm := _CreateForm(TWaitForm, {Application.MainForm}AParent) as TWaitForm;
WaitForm.Show;
...
end;
function _CreateForm(InstanceClass: TCustomFormClass; AParent: TCustomForm): TCustomForm;
var
LOwner: TComponent;
begin
if Assigned(AParent) then
begin
LOwner := AParent;
end
else if Assigned(Application) then
begin
LOwner := Application;
end
else
begin
LOwner := nil;
end;
result := InstanceClass.Create(LOwner);
end;
2%的客户的错误消息:
未找到资源TWaitForm
但是,其他形式正在发挥作用。
我能想到两种理论:
1)资源转换是否损坏了RCData
部分的DLL文件/部分? (可能是WinAPI的UpdateResource中的一个错误?)
2)等待表单的动态显示是否存在问题(因为显示了其他&#34;静态&#34;表单?)
