关于DLL组件问题。提示:Control '' has no parent window

tengjian1981 2005-06-02 04:07:57
我在DLL程序中写了一个过程:
procedure OpenForm(mainForm:TForm;DS:Tdataset);stdcall;
var
Form1: TForm;
ptr:PLongInt;
QuickRep1: TQuickRep;
begin
ptr:=@(Application.MainForm);
ptr^:=LongInt(mainForm);
Form1:=TForm.Create(mainForm);
QuickRep1:=TQuickRep.CreateParented();
QuickRep1:=TQuickRep.Create(Form1);
QuickRep1.DataSet:=DS;
QuickRep1.ReportTitle:='DLL';
QuickRep1.Zoom:=100;
QuickRep1.PreviewModal;
end;
但是在另外的程序中调用是提示“Control '' has no parent window”
而我把这个过程直接写在程序中,不用通过DLL来调用就不报错!

望高手来赐教,在线等

没看代码 看了错误信息,可以认为 你引用对象是继承来的,而你没有添加对象的父类

我是这样写的:
var
DS:TDataSet;
begin
DS:=DataSource1.DataSet;
OpenForm(Application.MainForm,DS);
主要是这个QuickRep1:=TQuickRep.Create(Form1);可能有问题

看你的写法程序应该是Mdi多文档的界面了
不知道你调用时怎样写的你如果传第Application.mainform 应该不会错,如果传self 或按牛所在的form1 肯定要错。

Download: Cheat Engine 6.5.1 Fixes: Fixed increased value by/decreased value by for float values Fixed disassembling/assembling some instructions (64-bit) Fixed the autoassembler tokenizing wrong words Fixed several bugs related to the structure dissect window (mainly shown when autodestroy was on) Fixed a small saving issue Groupscans now deal with alignment issues better Fixed java support for 32-bit Additions and changes: Signed with a sha256 signature as well (for OS'es that support it) Changed Ultimap to use an official way to get the perfmon interrupt instead of IDT hooking (less BSOD on win10 and 8) Individual hotkeys can now play sounds Now compiled with fpc 3.0/lazarus 1.6 (Previously 2.7/1.1) You can now search in the string list PEInfo now has a copy to clipboard Some places can now deal better with mistakes Lazarus .LFM files can now be loaded and saved lua: Fixed several incompatibilities between lua that popped up in 6.5 (due to the lua 5.1 to 5.3 change) Fixed the OnSelectionChange callback property in the memoryview object MemoryRecords now have an Collapsed property Added TCanResizeEvent to the splitter Fixed setBreakpoint not setting a proper trigger if not provided Fixed executeCode* parameter passing Fixed several memory leaks where unregistering hooks/addons didn't free the internal call object Some tableFile additions Fixed registerAssemble assembler commands Added kernelmode alloc and (un)mapping functionality Added an easy way to add auto assembler templates Added window related functions including sendMessage Added Xbox360 controller support functions Added more thread functions Post release fixes: Dealt with several gui issues like the mainform to front on modal dialogs, header resizing stuck with the cursor, treeview item selection/deletion being weird, etc... Added a disconnect to the client in pointerscans Fixed pointerscan issue with 32-bit aligned pointers in a 64-bit process Fixed a deadlock in threads when lua custom types where used Post release fixes: Dealt with several gui issues like the mainform to front on modal dialogs, header resizing stuck with the cursor, treeview item selection/deletion being weird, etc...

(symbols, scanspeed, threads, etc...) Fixed "going to" 64-bit registers. Fixed pointerstrings for 64-bit Fixed the addressparser in memview's hexview not handing static 64-bit addresses Fixed r8 and r9 looking broken in the memoryview window Fixed hotkeys that set a value as hexadecimal and the value is smaller than 0x10 Fixed multiline string editing for memory records Fixed dragging cheat tables into CE Fixed VEH debug for 'Modern' apps Fixed several translation issues lua: fixed getStructureCount, writeRegionToFile, readRegionFromFile, readInteger, ListColum.GetCount fixed memoryleak in MemoryStream Several fixes to DBVM: added support for Windows 10 support for more than 8 cpu's support for newer cpu's fixed issue where calling CPUID right after setting the TF flag wouldn't trigger a breakpoint after it Additions and changes: Array of Byte's can now deal with nibble's. (e.g: 9* *0 90 is now a valid input- and scanstring) The auto assembler can now deal with some mistakes like forgetting to declare a label Added support to use binutils as assembler and disassembler, and a special scripting language for it Added support for 64-bit mono, and script support for cases where mono.dll isn't called mono.dll Added an option to get a list of all recently accessed memory regions. This is useful for the pointerscanner The pointerscanner can now use multiple snapshots (pointermaps) to do a scan. This basically lets you do a rescan during the first scan, saving your harddisk Made the pointerscan network scanner a bit easier to use. You can now join and leave a pointerscan session You can now stop pointerscans and resume them at a later time Pointerscan files can get converted to and from sqlite database files The pointerscan configuration window now has an advanced and basic mode display The all type now has a setting that lets you define what under "all" falls Custom types now also have access to the address they're being used on Split up the "(de)activating this (de)activates children" into two seperate options (one for activate, one for deactivate) Added some basic Thumb disassembling The xmplayer has been replaced with mikmod which supports many different module types (in lua you still call it xmplayer) Rightlicking on "your system supports dbvm" will let you manually load DBVM for each cpu. This is usefull if for some reason your system crashes when it's done too quickly In "Find what addresses this instruction accesses" you can now open the structure dissect window of your choice in case there are others. It will also fill in the base address, so no need to recalculate yourself AA command GlobalAlloc now has an optional 3th parameter that lets you specify the prefered region Added an option to record and undo writes. (Off by default, can be enabled in settings. Memview ctrl+z will undo the last edit) Added aobscanregion(name,startaddress,stopaddress,aob) lua: switched from Lua 5.1 to 5.3 debug_setBreakpoint can now take an OnBreakpoint parameter that lets you set a specific function just for that breakpoint added dbk_getPhysicalAddress(int) added dbk_writesIgnoreWriteProtection(bool) added getWindowList() And a bunch of other lua functions. (check out main.lua) Post release fixes (max 7 days after initial release *or 30 if a HUGE bug): 1/6/2016:Fixed structure dissect from crashing when autodestroy is on 1/6/2016:Fixed window position loading on multi monitor systems 1/6/2016:Fixed the lua customtype and 1/6/2016:Several minor gui fixe

It makes the code much more readable and is a new standard for VB programmers that is consistent with the standard that nearly all other languages adopted long ago. 153_VBnet_TOC 8/16/01 1:12 PM Page xvii xviii Contents Chapter 5 .NET Programming Fundamentals 171 Introduction 172 Variables 173 Constants 175 Structures 176 Program Flow Control 178 If…Then…Else 178 Select Case 182 While Loops 184 For Loops 186 Arrays 187 Declaring an Array 188 Multidimensional Arrays 189 Dynamic Arrays 191 Functions 192 Object Oriented Programming 196 Inheritance 196 Polymorphism 197 Encapsulation 197 Classes 198 Adding Properties 198 Adding Methods 200 System.Object 201 Constructors 201 Overloading 202 Overriding 203 Shared Members 205 String Handling 206 Error Handling 210 Summary 213 Solutions Fast Track 214 Frequently Asked Questions 217 NOTE When porting Visual Basic applications to Visual Basic .NET, be careful of the lower bounds of arrays.

Collectionsare groups of like objects. Collections are similar to arrays, but they don’t have to be redimensioned. You can use the Addmethod to add objects to a collection. Collections take a little more code to create than arrays do, and sometimes accessing a collection can be a bit slower than an array, but they offer significant advantages because a collection is a group of objects whereby an array is a data type. 153_VBnet_TOC 8/16/01 1:12 PM Page xix xx Contents Displaying Modal Forms 288 Displaying Modeless Forms 289 Displaying Top-Most Forms 289 Changing the Borders of a Form 289 Resizing Forms 291 Setting Location of Forms 292 Form Events 294 Creating Multiple Document Interface Applications 297 Creating an MDI Parent Form 297 Creating MDI Child Forms 298 Exercise 7.1 Creating an MDI Child Form 298 Determining the Active MDI Child Form 299 Arranging MDI Child Forms 299 Adding Controls to Forms 300 Anchoring Controls on Forms 301 Docking Controls on Forms 303 Layering Objects on Forms 304 Positioning Controls on Forms 304 Dialog Boxes 305 Displaying Message Boxes 306 Common Dialog Boxes 306 The OpenFileDialog Control 306 The SaveFileDialog Control 309 The FontDialog Control 311 The ColorDialog Control 313 The PrintDialog Control 315 The PrintPreviewDialog Control 316 The PageSetupDialog Control 321 Creating Dialog Boxes 322 Creating and Working with Menus 323 Adding Menus to a Form 323 Exercise 7.2 Adding a Menu to a Form at Design Time 323 Creating Dialog Boxes 1.Create a form. 2.Set the BorderStyle property of the form to FixedDialog. 3.Set the ControlBox, MinimizeBox, and MaximizeBox properties of the form to False. 4.Customize the appearance of the form appropriately. 5.Customize event handlers in the Code window appropriately. 153_VBnet_TOC 8/16/01 1:12 PM Page xx Contents xxi Dynamically Creating Menus 326 Exercise 7.3 Adding a Menu to a Form at Design Time 326 Adding Status Bars to Forms 328 Adding Toolbars to Forms 330 Data Binding 332 Simple Data Binding 332 Complex Data Binding 333 Data Sources for Data Binding 333 Using the Data Form Wizard 334 Using the Windows Forms Class Viewer 338 Using the Windows Forms ActiveX Control Importer 338 Summary 340 Solutions Fast Track 340 Frequently Asked Questions 344 Chapter 8 Windows Forms Components and Controls 347 Introduction 348 Built-In Controls 348 Label Control 351 LinkLabel Control 354 TextBox Control 357 Button Control 361 CheckBox Control 364 RadioButton Control 365 RichTextBox Control 367 TreeView Control 369 ListBox Control 371 CheckedListBox Control 374 ListView Control 376 ComboBox Control 381 DomainUpDown Control 384 NumericUpDown Control 386 PictureBox Control 388 TrackBar Control 389 Adding Items to a Combo Box at Design-Time 1.Select the ComboBox control on the form. 2.If necessary, use the Viewmenu to open the Properties window. 3.In the Properties window, click the Itemsproperty, then click the ellipsis. 4.In String Collection Editor, type the first item, then press Enter. 5.Type the next items, pressing Enterafter each item. 6.Click OK. 153_VBnet_TOC 8/16/01 1:13 PM Page xxi xxii Contents DateTimePicker Control 391 Panel Control 394 GroupBox Control 396 TabControl Control 397 Creating Custom Windows Components 399 Exercise 8.1:Creating a Custom Windows Component 399 Creating Custom Windows Controls 403 Exercise 8.2:Creating a Custom Windows Control 404 Summary 407 Solutions Fast Track 407 Frequently Asked Questions 408 Chapter 9 Using ADO.NET 409 Introduction 410 Overview of XML 411 XML Documents 411 XSL 411 XDR 412 XPath 412 Understanding ADO.NET Architecture 412 Differences between ADO and ADO.NET 414 XML Support 414 ADO.NET Configuration 415 Remoting in ADO.NET 415 Maintaining State 415 Using the XML Schema Definition Tool 416 Connected Layer 417 DataProviders 418 Connection Strings 418 Exercise 9.1 Creating a Connection String 419 Command Objects 421 DataReader 425 DataSet 426 XML Documents XML documents are the heart of the XML standard.
